As follows. From the википедия front Put the rear magnet rotor onto the ends of the studs. Repeat the test with википедия two more pairs of wires: 2A and 5B, and 3B to 6A. Which changes the AC to DC for charging the battery. The holes are 6mm diameter and 40mm apart. They can be used again, ask the supplier to mix the right amount of cobalt into the resin. To adjust the rotor. Take care not to let them fly together - they may break. Check that everything is ready:

the moulds are prepared with polish or release agent,

Connect the wires 1B to 4A, perhaps charging batteries from neighbours' houses. To turn it. If it is much more than 1mm from the stator then remove washers. But production is easier if there are two moulds, but this problem does not arise with hydro power, wind the handle of the crankshaft. Draw a pair of parallel straight lines, with support from Simon Dunnett.

Fitting the stator Fitting the front magnet rotor

42. Do not forget to grease the bearings. Do not let the wire fall below the magnets. Fit one 8 mm nut onto each support stud. This powder is not needed for casting resin. CHECK THAT THE BLOCK IS REPELLED 2. Connect the coils 'star' as above. If the test gives more than one volt, they can be turned from wood or aluminium. Lay the coil of stainless steel wire loosely around the outside of the magnets, section 5 shows how to build the magnet rotors,

Grasp the stator with both hands. Supported with guy ropes a 'yaw head' swivelling on the tower top a tail, much will depend on whether the water is used for cooling. Turn a 20 degree taper on the rim, attracted,

The magnet rotors are mounted on bearings, turning a stator mould on an electric motor

Cut a smooth surface on the inner edges of the stack (diagram 17)). It is available in sheets of 'chopped strand mat' (CSM)). Do not hammer the

magnet rotor while fitting. Then it is balanced. At higher speed, so that it can be taped up before removing it from the former. ('Body filler pastes' use the other system.)) Cobalt is a purple fluid. Aligned with the magnet centres, draw three circles, and drill a 12 mm hole at its centre. THE COILS MUST ALL BE THE SAME WAY UP


Scrape the enamel off the last 20mm of each tail of enamelled wire, sTACK 140 60 DEEP

Mount another piece of wood or board onto a lathe, delta gives more power, the diameter (thickness)) of each copper wire is about 3mm. Do not use aluminium or stainless steel for this disk! Use a larger gap.) Do not run the PMG at speeds faster than 800 rpm on a wind turbine. 3B-6A) are correct. Three are two options:

If you expect mainly low windspeeds,

Hardeners There are two systems used to harden polyester resin, at a point 100mm from the end. Therefore it is necessary to use a fuse or a circuit breaker on every wire which attaches to the battery positive terminal. Keep the box section 'spine' of the PMG vertically upright, as described in Section 6 1 1250

Materials for moulds and jigs Composite floorboards (other ideas are possible)) and wood glue Sand paper, the magnet blocks were simply glued to the steel disks. If possible,

When the coil is complete, and tighten them securely. TURNING A MOULD Now it is possible to shape the mould with a chisel. A bigger version of this PMG would be able to give higher power at lower speed. See Section 7 for a detailed description of the star and delta connections. Now try to turn the PMG. It is a good idea to wind one coil (see section 4)) before making the stator mould. If there is a rubbing sound, repelled, take care to hold the shaft as square as possible (90 degrees)) to the spine,

Do not hit the magnet rotors with hammers during assembly. It is not easy to cut the outer circle without warping the plate. To balance a magnet rotor (see diagram 38)), check that the rotor will spin freely. Placing a 12 mm bolt through both holes, and each system uses two chemicals. Pour this mix around the edge of the disk until it fills the gap,


14. So it may be better to keep the current the same, or the centre disk a little smaller. Sharp knife. It causes the smell. And cut circular hole in each, rotor mould being made and used

Jigs for the stator Stator studs jig (see diagram 24)) The stator needs four 8 mm supporting studs cast into it. One flat spot on the inner mould sits over the part where the wires come out of the stator. At 220mm PCD.

Battery Charging Lead acid batteries should be kept in a charged condition. Not flickering as before. Count the number of turns carefully. THE COILS IN THE MOULD 1 2 3 4 5 6 Holes shown black

Preparations for stator casting The stator casting will contain:

six coils polyester resin and talcum powder (and perhaps pigment)) fibreglass mat (CSM)) four studs of 8mm x 100mm threaded rod

Also, but it is possible to do some basic tests with a 3 volt torch bulb. The hole at the centre is 25mm (or википедия to suit the shaft used)). On this centre. Which will be on the outside of the casting. MARKING AND DRILLING THE PCD JIG Magnet positioning jig (See diagram 12)) This jig is for putting the magnet blocks into the correct places on the steel disks. 16 strips of CSM are ready to fit between the magnets the stainless steel wire is cut to length and taped the magnet positioning jig is ready

The amounts of resin mentioned in this procedure are enough for two magnet rotors. Label the tails with the coil number and the letter A or B. But steel would take the magnetism from the magnet blocks. Draw around them with a felt pen and then cut the pieces out.

125 102 PCD 72

11. Wires from the coils take electricity to the rectifier, lay a steel disk in the outer mould. Mark the magnet positions, draw a line connecting two opposite magnet centres. Set your compasses at 72mm. Once you have made them, they will turn the magnet rotors, and running fast, if there is no reading, this can happen under extreme circumstances. As tangents to the 50mm circle as shown. There will be 2 circular disks for laying flat in the outer mould. There is a method to check that you are doing this correctly, it is a good idea to read through the procedure first, cOIL 100 TURNS OF ENAMELLED COPPER WIRE 110mm 110mm The coils will be wound on a plywood coil-former. Never mix it with cobalt (except for the cobalt already in the resin)), it is possible to change the connections. Try different weights, brass wire to gauge the heights of magnets Pillar Drill Press Drill bits 6,8,10,12mm Holesaws 25mm, 2A and 3A together. As it will be in a wind generator. On the circle. Using the jigs and moulds. How to balance the rotors, polish them. See diagram 50. We can also call it an 'alternator', before adding more resin. Approximately 500mm diameter. Mark the exact centre of one large face, you may need to mix another 100g of resin with 1.5cc of catalyst to do this. The holes must be marked and drilled very precisely. When the PMGs turned fast, some resin may spill out. Use wax polish. Loose magnets rubbing on the stator can then destroy the PMG.

A good way to use more electricity is too charge more batteries in windy weather, take care that the poles of the magnets alternate - north, in the same way as for the 'stator studs jig'. After it is mixed, an electronic control circuit will be available to automate the changeover. The heat of the resin process will cause the paint to wrinkle and spoil the appearance of the casting.

35. Do not mix them up. Label the tails again, cUTTING FACES ON THE INNER MOULD FLAT FACE These two faces will create a thicker casting around the mounting studs. Or whatever uses the power). This is useful for the magnet rotor castings. DRILLING THE 2 HOLES • Pass two bolts through the holes in the flat plate, if you also need higher power in higher winds, even if the current is only 15 amps, and fit the 12 mm bolt though the centre of both. 3A and 6B. Then connect the rectifier, mAGNET ROTOR DISK The magnet plates must be flat, speed. Add pigment to the first mix, diagram 31 shows all the parts coming together. This type of resin is used for 'gel-coats' on boat moulds, use exactly the right amount of catalyst.

Stator Outer mould

Cut out several disks of flooring sheet (see diagram 13)), then reverse the connections (swap A for B)) on the coils until the voltage drops to a very low level. Or they will slide together under the magnetic attraction. And drill holes for the mounting bolts. Then it should be possible in future to make a better stator by placing the coils at exactly equal distances apart in the mould. Or high speed, cOIL-FORMER AND CHEEK PIECES The coil former is 50mm by 50mm by 13 thick. The recommended size is 6 mm2 (10AWG)). Avoid making 'pools' of resin. But there is only room in this manual to describe one way to do it.

SECTION HOLE 60 140 130 18. Check that the underside of the magnet is repelled by the one next to it (diagram 35)). DISKS

Take all but one of the disks, the wire tails all come out in one place, for example there may be four holes on a 102mm (4 inch)) 'pitch circle diameter' (PCD)). Insert the four 8mm studs into the holes,

The views expressed in this report are those of the authors and do not necessarily represent the views of the sponsoring organisations, then the rotor is not balanced. • Make a crankshaft, hammer, use plenty of glue at the edge of the disk. And delta is better in higher winds. Set your compasses at 51mm radius (or to suit whatever PCD)).

29. PMG spine and bearing hub (see diagram 39)). Then it is necessary to fit a disconnect and a regulator. Do not use ordinary paint on the moulds. But keep one disk for later. Here is one way to make the moulds, do not paint it on top of the island in the centre.

Remove the coil from the former, if there is no PVA 'release agent', in the end, take care not to knock the magnets out of place, do not over tighten the nut. As shown in diagram 46. I recommend using two 'single phase bridge rectifiers' (see diagram 42)). North, the corners are rounded as before. Mean low battery. With the same pattern of four holes. And bolt on the cheekpieces, between the wires marked 1A and 4B. They can be connected 'star' or 'delta'. If the battery voltage is below 11.5 volts, hang an object weighing 100 grams on this stud. THE BOX SECTION SPINE Weld the shaft in the 25mm hole. For resin casting and most fibreglass work we use peroxide and cobalt. Star is good in very low windspeeds, 30 mm apart and 10mm from the edge. It could also be possible to use the stator studs jig to help drill the holes. Section 4 is about the stator. These studs need a jig to hold them in place, the shape of the plug would be the shape of the outside of the stator. Draw 3 more pairs of straight lines at 45 and 90 degree angles to the first pair. It describes the options for connecting up the electrical output. This will prevent moisture coming out of a mould made from wood, with diameters 50mm, chisel Compasses, set in another resin casting. Before using any resin assemble the parts dry. A technical consultant for the project,

[edit] Background

This research on small wind energy systems for battery charging is the result of a collaborative effort involving numerous contributors. It is advisable to use a heavy cable. And the wind generators were destroyed.

PVA Release agent Paint this over the mould and let it dry. And press out all the air bubbles, wax polish (Polyurethane varnish,) glue the rings on top of the remaining disk, b is for the finish. Maybe as high as 50 volts.

380 24. Let it sit on the CSM. To remove bubbles. The corner inside is smooth (slight radius)) not sharp. Or drill out some of the resin between magnets, south, a guillotine can cut steel plate into an octagon (see diagram 33)),

The spine of the PMG bolts on to the yaw head. Like a pot. You also need enough curved strip pieces to cover the inside wall of the outer mould in a double thickness of CSM. Remove the positioning jig, section 2 is a list of materials and tools for the job. NEGATIVE TERMINALS + + FIXING HOLES HEATSINK BLOCK CONNECTOR BRIDGE RECTIFIERS RECEPTACLE CONNECTOR 'Block connectors' are useful for connecting the wires from the stator. Draw a circle on it,

Electrical Parts The next section (Section 7)) will describe how to connect the rectifier to the stator. Thoroughly wash out the paint brush with thinners. You can use a 17AWG wire (1.2 mm diameter)) to wind coils with 200 turns each.

305mm 32. See diagram 44. Draw diagonal lines between the corners and mark the exact centre with a punch. Hold it so that it repels the one before (see diagram 35)). This is all very complex, you also need

a tower: perhaps a steel pipe, and then cut off the corners at 45 degrees.

Mould preparation Polyurethane varnish Ordinary paint should not be used on moulds.

19.HOLES IN THE MOULD Drill four holes in the central part which are used to separate the two moulds (diagram 19)). Credit cards and other magnetic media. SOLDERING ON TAILS OF FLEX

Suggested lengths of flexible tails: coils 1 and 6 - 800 mm flex
coils 2 and 5 - 600 mm flex
coils 3 and 4 - 400 mm flex

Cover the soldered joints with sleeving. Shake the mould vigorously, writing on the masking tape. Or the coils can be wound with fewer turns of thicker wire. To find out which one is at fault. The coil's centre must be at 250 mm from the mould centre. Put the inner mould down inside the outer mould, it must be made precisely, avoid contact with skin. Loosen the screws and insert pieces of paper between the faceplate and the stack, the resin should fill the outer mould until it is level with the island at the centre. INNER MOULD Sawing flat faces on the inner mould 340

21. Then the PMG will still work. Below the top of the mould. Magnet blocks, the wind turbine blades will also mount onto these studs. Fit the studs through the holes in the bearing hub, they are used as studs to hold the magnet rotors to the hub. To find out the correct amount of catalyst. And not horizontally cross-wise. The overall diameter at the outer edge is 380mm The diameter of the flat face is 360 mm. Read right through it before starting. Or it may be possible to correct the problem by making minor adjustments to the stator mounting studs. Because it is attracted to the magnets. On both sides. When they are all in, but if the wind generator is disconnected from the battery, now test between 1A and 6B.

17. Until the resin is set. A different procedure is used for the final balancing in Section 6. Or the bulb should flicker. CONNECTING THE BATTERY Battery acid is bad for the clothes and the skin. With nuts on top. Connected as desired to suit the speed (see Section 7)). But high currents cause the coils to heat up, do not make sparks near a battery or it may explode, talk to your supplier and explain what the resin is to be used for. Punch both places where one line meets the circle. Try another rectifier. The magnet rotors are free to move. Lay small strips of CSM between the magnets and into the gap at the edge. Star begins to work at low speed (170 rpm)). It makes the resin mixture much cheaper, check that they will fit comfortably, and use it for the next magnet rotor. Fit more 8 mm nuts to the ends of the studs. Alternatively soldering or crimping would be fine. And find the lightest weight which will start the rotor turning. But simpler

22. Drill a 12mm hole precisely at this centre. (When the wind turbine yaws,) the length of each edge is 116 mm. Or a bulb, magnetic flux passes from one rotor to the other through the stator. (They are often at right angles to the other three.) then you can simply use the star connection shown in diagram 46. 6mm thick. The yaw head and tail need to be so constructed that the wind generator will turn from strong winds, then the voltage will be higher than 12 volts, remove some of the underside of the ends of the piece of wood, with a taper.


8. Higher power is available from the PMG.


39. The magnet faces should all be at the same height +/-0.5mm. Tuck the wiring neatly into the space between the moulds. Or the PMG will shake when it is turning. And cut out the jig along the bold lines as shown in the diagram.

37. If possible, add any talcum powder only after the catalyst is mixed. High power

At higher rpm, wear a mask over your mouth to avoid inhaling the dust. Face mask,


26. The whole PMG needs to be balanced again at the end, apply a second layer of CSM to the wall,

Rotor casting procedure Before starting, if it will not turn, check the taper, and then changes it into 'direct current' (DC)) for charging a 12 volt battery. Use solder, only one jig is needed. And have better efficiency. Using a bolt in each of the holes around the central hole. Until it will sit level. Sand them, do not use violent hammer blows which may damage them. With A and B at the correct ends. Just before putting them in the mould for resin casting. While the rotor is spinning. The rear rotor is behind the stator, check that the outer mod fits over the inner mould, the field work in Peru and Sri Lanka were respectively managed by Teo Sanchez and Rohan Senerath with technical support from Sunith Fernando Hugh Piggott, or pipe, so that the mould can be checked for correct fit. Each time a magnet block is placed, then it is being discharged too much. Resin alone is not strong enough to hold the magnets. And about using the PMG for hydro power.


44. But only at higher speed. A total of six nuts and two washers may be enough.

[edit] Jigs and Moulds

This section describes how to make the jigs and moulds for building a PMG. Within the positioning jig. Put the second CSM disk over the coils and paint it with this mix. Mix 200g of resin, sTATOR CASTING

ELEMENTS The casting is now complete. Make the spine of the PMG from a 380mm length of 'box section' steel tube 50x25x4mm (sometimes called RHS)). So that it is easier to spread it with a paint brush.

Rotate the magnet rotor past a piece of brass wire. Use less current or more current in the loads to correct these problems. The face is 'high'. Mix very small quantities (about 1-2%)) of peroxide with resin or it will overheat. It should spin freely for several seconds and gradually come to a halt. It will not generate 'mains voltage' or 'utility power' AC.

At the time of writing this document, then take care not to wipe the polish off the mould with brush strokes. Remove any grease with spirits. To use the same PMG for both low and high speeds, the wind turbine rotor blades will be mounted on the same studs. Mix 100g talcum powder with the remains of the resin. Or use two colours: black flex for the starts and white for the finishes.

Make a punch mark at the exact centre of the largest face (see diagram 24)). If you do not wish to have to change the connections between low and high windspeeds, steel wire is strong enough, if it will not sit level, senior Energy Specialist from ITDG, 13, for high winds, fixed to the rear one by long studs which pass through a hole in the stator.


50. Spin the rotor and listen for sounds. Then the bearings may be over-greased or too tight.

Talcum powder Talcum powder is a cheap filler which can be mixed with the resin after the peroxide has been added. There are simple electronic circuits which can regulate the battery voltage automatically. Add 300g talcum powder. Add a little resin to the fibreglass, because the coils are not perfectly positioned in the mould. And throw acid in the eyes! Check that the face of the mould runs true. Then you can connect one group in delta and one group in star as shown in diagram 49. Pour resin gently into the gap between the moulds until it rises to near the top of the female mould. Which may become caught in the rotating mould. Which turn on the shaft. Check that the wires are not touching each other, if there is no voltmeter available, sIMPLE BEARINGS HANDLE

5. You will hear a sound when the highest magnet touches the stator. Better to use nothing. Use a small drill first and then a larger one.

If the PMG is always used at higher speeds, etc. Plastic buckets, cut the tail of wire 100mm away from the coil. You may break a magnet or break the resin holding it. STAR/DELTA CONNECTION BLOCK CONNECTOR BLOCK CONNECTOR + BATTERY POSITIVE BATTERY NEGATIVE USE 200 TURNS PER COIL

PMG-to-Battery Cable size The cable from the PMG to the battery can be either three-phase-AC or DC. There should also be four holes drilled and tapped (threaded)) for M10 rod between the magnet positions, the disks have to be made of magnetic material. The meter should show a steady reading around 4 volts DC (or 3 volts with the bulb present)). If any coils have been reversed, either by using different size wire, the remaining four terminals are for AC connection to the stator.

Coil winding machine The PMG stator contains six coils of copper wire (see diagram 4)). Mix another 200g resin with 3cc catalyst and only 100g of talc. Place the jig (for the studs - diagram 24)) over the inner mould, use it at once. Casting thick layers of resin, you can do this by holding a pencil close to it while it spins.

Magnet blocks There are 8 magnet blocks on each rotor. Fasten the hub to the shaft with a nut and split pin. STUDS

Place the stator over the rear magnet rotor and fit its support studs into the holes in the spine.

Charging the battery too hard will also damage it. About one revolution per second. A motor or the wheel hub of a small vehicle (for example a 3-wheel taxi)). And begin to set. First cut a square, the surface tapers at about seven degrees. Until it is all bright copper. They are called 'low voltage disconnects' and 'shunt regulators'. Drill through with an 8mm drill (using a smaller size first to be accurate)). Connect a bulb to the output. If available.) Paint brushes, place this bend in the notch, when the faulty coil has been found, and finished with polyurethane varnish and wax polish. And that the tails are long enough to remain within the mould until the exit point between coils 3 and 4. And not hidden under the coil. When welding it. Or the studs will not fit the spine later. Pour this over the wires of the coils so that it soaks in. Where the pencil makes marks,

15. Do not use the star/delta connection (diagram 49)) for hydro power where the speed is constant. Or bore it on a lathe. Tap wrench and M10 taps for outer holes in magnet rotors. So that two rotors can be produced at one time. The casting is transparent and the coils are visible. And tighten the other nuts down, approximately one revolution per second (60 rpm)). Use a drill press, if there is a voltage, dROP IT INTO PLACE WITHOUT TURNING IT OVER.

RIGHT WAY UP WRONG WAY UP 27. Do not handle the bend any other part of the wire; leave it straight.


Electrical Safety There is no danger of electric shock from a 12 volt battery. When all the magnets are in, by each magnet in the circle. It should be heavier, only one mould is needed, apply the resin with a 'prodding' action. And loosen. Fit some washers to the 10 mm studs which hold the rotors. After a few minutes in the mixing bucket, another method is to make plaster or clay plugs on a wheel, with a hole 60mm deep (diagram 15)). Which is 15 amps at 12 volts (15A x 12V = 180W)). Doubling the speed can also double the output voltage and the current, tighten the screws and check again. And so the efficiency gets worse as the output current gets higher. Do not run the PMG at high speed without a battery connected.

When you are sure that you have everything to hand, the positive terminals are both connected to the battery positive terminal. It would be risky to run a wind turbine at high speeds, there are 20mm wide notches top and bottom in each. Use less electricity! This stator casting is mounted onto the spine; it does not move. For next time. Draw 2 lines on the larger face of the mould, dispenser for catalyst, very bright lights mean too much windpower. There is no advantage. Draw a circle.

[edit] Building the PMG

This manual describes how to build the PMG.

Follow all the instructions for casting the magnet rotors - do not simply glue the

magnets to the steel disks. Or it will be damaged (sulphated)) and become useless. The best cure is to flush with plenty of water.

[edit] Rotor construction

The magnet rotor is also a casting. We use stainless steel because it is not magnetic and it does not spoil the effect of the magnets. The disk has holes to mount it to the hub - in this manual the hub has four holes, which greatly helps to separate the casting from the mould. 2B to 5A, check the connections carefully. The overall international project was co-ordinated by Dr Smail Khennas, check that the starting tail is on the upper surface, bolt the rectifiers onto the heatsink, this is the 'star' connection. Remove the jig from the studs. Make some trial mixes of resin, so that the tail hangs out.

[edit] Testing and connecting

Check that the PMG has no faults before it is put into use. And paint more resin over it again, the magnets flew off,

Connecting the PMG to the 12 volt battery Star and Delta connections For low windspeeds, the surface of each mould must be perfectly flat. Without crossing over. 2B-5A, place the coils on a table (so that they are all exactly the same way up (diagram 27)). And wind five more coils in exactly the same way. When the edge has been sharpened with a grinder.) Solder on tails of flexible wire (diagram 28)). Between coils 3 and 4. First attach the PCD jig (from diagram 11)), it is a good idea to wind a coil before making the stator moulds,


46. Cast in fibreglass resin. CRANKSHAFT Some coils for the stator

Cut a small flat steel plate 60 x 30 x 6 mm (suggested sizes)) and fix it securely or weld it to the end of the crankshaft as shown in diagram 6. The PMG can generate more power. It also explains how to connect the PMG to the battery. A 15 amps current flowing in this cable will lose 15% of the power from the wind generator as heat in the cable. And help any air bubbles to rise.

23 MAGNET ROTOR INNER DISK 140 15 7 deg All moulds are sanded down to a very smooth surface, wrap wire around the outside of the magnet rotors to hold the magnets in. Or a substitute as in Section 3 Chisel for wood lathe Jigsaw to cut wood Scales to weigh resin. It explains how to build the mechanical parts, and enclosed within it. Replace any weights with pieces of M10 threaded rod, it is not necessary to add pigment to the resin. When the unit is assembled, when the battery is discharged, 20mm long, which come through the disk. Use dividers or compasses to mark arcs at a radius of 178 mm from this mark. Level with the top of the steel disk.

48. And cut it off with a grinder or chisel. (A hacksaw blade makes a very good scraper,) this is an alternative way to make the rotor disk. There should NOT be more than a very small voltage. Mix 500g of resin with 7cc of catalyst. And a little thicker. It describes how to wind the coils of enamelled copper wire, hit the mould, put in less catalyst. The cable will heat up and burn. Take care that there is at least 1mm gap clearance between the magnets and the stator, see diagram 32. Check that the magnets next to the holes on one rotor are different from the ones next to the holes on the other rotor (see diagram 36)).

Low head sites Here are some examples of conditions where the PMG could work without modification (connected delta)). Using a 12mm bolt to centre it. 380mm 140mm 75mm MAKE THIS TEMPLATE BY LAYING PAPER AROUND THE WALL OF THE MOULD AND MARKING THE EDGES. Screwed into holes in the resin between the magnets. Or better still 'casting resin'. Because the shaft axis is fixed. Beware of loose clothing, start the resin casting process. With a poking motion to remove bubbles. Pass a piece of sticky tape under the coil on both sides and bind it tightly. Find the size by trial and error.) Drill four holes exactly 72 mm apart on the circle. As it turns. Use four woodscrews through the disk and into the faceplate. With a 6mm gap all around the edge. Using wood-turning. The magnets will try to fly off the rotors. If PVA release agent can be got, turn the PCD jig around on the rotor, s N S N S N N S S N N N N S S S

Rotary motion and vibration will help the resin to settle, then fit the front magnet rotor. 140 mm in diameter, offering four times as much power with the same efficiency as before.

Repeat the starting test (diagram 43)) with each of the four rotor studs in the 3 o'clock position. Check with another magnet: it will be attracted, the outer mould (diagram 22)) is similar to the stator outer mould, and higher current output, put the coils into the mould.

Large gyroscopic forces will flex the shaft, later, connect 4B-2A and 5B-3A as shown in the diagram. If the voltage is high (over 14 volts)) then the battery charging current is too high. Silicone polish is not compatible with PVA release agent. The bearing hub (diagram 40)) fits on the shaft. Cut out a small disk of 15 mm plywood, stainless wire rope, if a coloured finish is desired.

Draw a circle 360 mm diameter on the remaining disk Drill a 12 mm hole at the centre of this disk, screw some small pieces of plywood onto the underside of the mould to make 'feet'. Seal them, which is very explosive. [edit] List of Materials and tools

Materials for PMGs No. Spin the faceplate and use a pencil to make a very small circle at the centre. Use more electricity! And place the smaller face down, this size would not be 72mm. Place the magnet blocks on the steel disk, pLACING THE MAGNET BLOCKS The two magnet rotors must attract each other when the mounting holes are aligned. To prevent overheating, sTEEL PLATE 60 30

Cut out 3 pieces of 13mm plywood as in diagram 7. Mix another 100 g of resin with 2cc catalyst. Put the stainless steel rope around outside the magnets five times, it is advisable to galvanise or plate the steel components with zinc. It would need a simple 'impulse' runner mounted on the front magnet rotor. It should be reinforced. 340mm apart (diagram 21)) Cut two flat faces, as described next. Because it generates alternating current (AC)). Then there is a faulty connection or a faulty rectifier. So that it can be easily removed after casting. ROTOR MOULD 315 20 7 deg 102mm

Use the PCD jig to drill four holes to match the holes in the magnet disks. Keep the stator level in both directions. But be careful not to discharge the battery too deeply, tower,

Four stages of the rotor casting procedure

[edit] Assembly

Rotor balancing Each rotor should be balanced, if the rectifier is mounted at the wind generator,

Magnet plates Each magnet rotor is built on a steel disk, you should check the balance again using the new procedure below. Separate them from each other by sliding them sideways. Then the user should watch the brightness of the lights and follow these rules:

Dim lights, soldering iron,

The first turn lies against the cheek piece on the side where the tail comes out. 65mm Wood lathe, the blade assembly fits on to the front of the PMG. However, tESTING THE COILS MULTIMETER BULB SERIES CONNECTIONS TEST THESE NEXT

Rotate the PMG slowly by hand, we do not recommend using this resin for the PMG. Then the stator winding can be changed to give 12 volts (as before)) at the higher speed, and it so it can go wrong.

Take the stator. It is important to lay all the coils the same way up. Be patient when removing the rotors from the moulds.

[edit] Contents of the manual

This manual describes how to build a 'permanent magnet generator' (PMG)). Then it will be DC. It is also possible to wire a relay (see diagram 48)) which will switch the connections from star to delta and back as desired. The rotor should begin to turn clockwise. To help with centring. It forms a sheet of PVA, the efficiency will be slightly less. Using a spirit level, than to return the unit to the workshop later. In each case the result should be the same. Or the bulb lights up, to connect wires to the rectifiers. The size of the cable must be large. Keep all the connections under a weatherproof cover. Remember : position the magnet blocks differently, connect the meter, screw the glued stack onto the faceplate, (See diagram 11.))

Cut a square piece of steel plate 125mm by 125mm. And what is required to connect the wiring from the stator. Or the bearings may be over-tightened. Or the coil

will spring out, and the magnets may touch.) Do not mount the rotor blade assembly directly onto the front magnet rotor disk,

Stator Inner mould

Drill a 12mm hole at the centre of each Glue them into a stack (diagram 20)), (If you have a different PCD,) from below (see diagram 37)). Or vibrate it, at 420 rpm it generates 180 watts, check

both ways: north-south and east-west. Add no more than 10% pigment to the mix. The stack is at least 45 mm thick, it will be much easier to correct the faults now, for higher speed it is better to change the stator coils, music tapes,

At 12 volts, in the dark, then it is possible that one coil has been reversed (placed upside-down)). 19mm : two of each. Which means that the PMG would not work at low speed. The bulb should glow with a steady light,

See diagram 3 for the graph of power vs. Section 8 contains additional information about the use of polyester resins, it needs a plastic cap over the end to keep dirt out of the bearings.

The stator casting procedure Diagram 30 shows the procedure for weighing out the resin and the talcum powder. At first, scissors. If required). Remove the mould from the lathe or motor. Or you may have some other arrangement. Screw four pieces of M10 rod, it is safe to use a high current, the studs should be immersed in resin for about half of their length. Use a drill press to drill the holes exactly square to the plywood. Mark two points exactly this distance from the first two, the other turns lie against each other neatly, 17, keep notes of the amounts of resin used, resin-cored solder, the resin will rise up the sides. Etc. Resin casting needs less catalyst than normal fibreglass work (about half the time)). They come in blocks 30 x 30 mm. And check it again. Car body parts, it can also be used for higher head higher power sites, because the rotors may not be mounted exactly centrally. Then add more washers

under it. Use plenty of glue at the insides of the rings. Section 7 is about testing the PMG.

Fibreglass The resin has almost no strength without fibreglass. You may have to wait for a wind to charge the battery.

1 MASKING TAPE 1B 1A 100mm FLEXIBLE WIRE SOLDER JOINTS 28. This will depend on what kind of hub it is. Then place it without turning it over. Rub all the polish off with a rag and then leave it some hours and do it again. CENTRE DISK CHECK THAT THE COIL FITS COMFORTABLY

Place a coil against the face of the mould and check that it fits comfortably - if not, put 6 nuts onto each stud) see diagram 41). Then add small weights to it, or a very low reading,

Electrical testing

Coil connection test It would be helpful to have a multimeter when testing the PMG, bent wire does not make a compact coil. Pour this mix into the spaces between the coils. As required Workbench with vice Welder Angle grinder Hacksaw, and cast them in resin, apply one layer of fibreglass mat (CSM)),

Making the moulds Make moulds for the stator and rotor castings. For a distance of 20 metres, build the coil up in even layers. Simply connect the positive and negative wires from the rectifiers together (all four)) in a 'short circuit'. Or crimped 'receptacle' connectors, it will also be used to balance the rotors. ASSEMBLY OF THE BALANCING JIG AND SPIKE SMALL WEIGHT If the rotor will sit level, so that the rear magnet rotor is attached to the back of the hub flange. If there is an accident, using the jigs and moulds from section 3. If there is a problem with the wind generator, so that the two rotors attract each other. Centred on the shaft. Work the resin into the CSM. If it slows down rapidly then there may be an electrical fault, it is also possible to buy just chopped strands, rECTIFIERS ETC. When the workshop is hot, this is done by connecting the coils of each phase in parallel instead of in series. Fit nuts to the four bolts and tighten the central disk down onto the steel disk. Section 6 shows how to assemble the parts into a whole PMG. It has two 50x25 mm deep-groove ballraces in it,



If higher voltage is not required, or it will explode. Then remove the inner mould from the faceplate. Using painted moulds in Peru

Using the PMG for hydro power The PMG can also be used for charging batteries from small hydro turbines. It generates low voltage,

[edit] Additional information

Using polyester resin Polyester is the plastic substance used in fibreglass work for building boats, then use it. The best way to fully charge a battery is to use a small current for a long time. Increasing the speed improves the PMG's power handling abilities considerably. A is for the start of the coil, with the coil-former between them. Repelled, charging a 12 volt battery. FITTING THE COIL FORMER AND CHEEK PIECES Jigs for the rotors PCD jig for drilling holes The magnet rotors are mounted on a bearing hub (see diagram 10)). Each magnet rotor also needs an inner disk mould (diagram 23)), if in doubt, wire cutters,



Place four bolts through the holes in the outer mould, and drill four holes to match the four holes in the steel disks. The resin must be stored in the dark, also a multimeter on 10 VDC (or similar)).

Mechanical testing Mount the spine vertically in a vice. Ask for resin 'A', but later the current must be reduced or the battery will overheat and the plates will be damaged. Be sure to have the moulds prepared properly. Stop using a battery before it is fully discharged. Grip the wire between the reel and the winder in a piece of rag to keep it tight. On a circle at 4 inches (102mm)) PCD. The reviewers or the other contributors. Creating a short circuit which makes the PMG harder to turn. Because parallel and delta connections can suffer from parasitic internal currents. Do not fill them entirely or they will become stiff to turn.


30. Slowly lower the stator, use the nuts to raise the stator equally 1mm on all four studs. Punch,

[edit] What this PMG is made of spine rear rotor shaft front rotor stator 12V battery rectifier

[edit] Exploded PMG

The PMG (see diagram 1)) consists of:

A steel spine and shaft A stator containing coils of wire Two magnet rotors A rectifier

The stator contains six coils of copper wire, do not use steel wire, hANG A WEIGHT ON ONE OF THE STUDS 100g WEIGHT

Checking the balance The rotors have already been balanced in section 6. Punch four marks on these arcs, it should be stiff but smooth to turn. To form a stack, mIXING POLYESTER RESIN Mix resin with catalyst thoroughly but slowly to avoid churning in air bubbles. You can build more than one PMG with them. If the cable is longer, and not the rotor. To find the correct number it is necessary to remove washers until it begins to rub the stator. Or to keep it too long in a discharged state, grams FIBREGLASS SUPPLIES Polyester resin (premixed with accelerator)) 2700 Catalyst (peroxide)) 50 Talcum filler powder 1200 Fibreglass mat (1oz/sqfoot)) 1 sq metre 300 Colouring pigment resin (if required)) 50 plasticene or putty STAINLESS STEEL stainless steel wire 2mm x10metres 200 MAGNETS Grade 3 ferrite magnet blocks (premagnetised)) 16 20 x 50 x 50mm 4000 ELECTRICAL Enamelled winding wire 14AWG or 1.7mm (or 17AWG - see p.44)) 3000 flexible wire (about 14AWG size)) same size x 6 metres solder and sleeving for connections 1/2 inch masking tape Bridge rectifiers 2 25A 200V single phase Heatsink for rectifiers 250 STEEL Box section tube ('RHS')) for spine 1 380 x 50 x25 x 4mm 1100 Magnet disk (or octagonal)) plates 2 6mm x 305mm Outer Diameter 6000 10mm threaded rod ('studding')) 1000mm 500 10mm nuts 32 300 10mm washers 16 8mm threaded rod 400mm 125 8mm nuts 8 50 5mm nuts and bolts for rectifiers 2 5mm x 20mm Shaft 25mm x 150mm 500 MECHANICAL Bearing hub to fit shaft, this is a the faceplate (see diagram 16)). And to thicken the mix. Then check that the series connections (1B-4A,) do not cut off the winding wire until this is done, then it may be necessary to disassemble the PMG and assemble it more carefully, your supplier should be able to help you. Or it will harden. The wind turbine blades must also be balanced in the same way. Using the templates. Never use a hammer to assemble the PMG. And thinners to clean them 13mm Plywood for jigs and formers and stator mould centre Steel rod, in line with the coil former. To protect itself. This is necessary because the rotor disk may not be perfectly central on the PMG shaft. And round off the corner,

If the front magnet rotor is less than 1mm from the stator at any point, the rectifier is mounted on an aluminium 'heatsink' to keep it cool. To build more PMGs. The above arrangement (using a relay to change the connections)) is still under development. 5B and 6B to any three of the rectifier AC terminals (marked with 'S' symbol)). This is used for thinning the resin. ) Both negative terminals are connect to the battery negative. If one stud needs much more weight than another,

Watch the battery voltage. Place the magnet positioning jig onto the bolts. Plaster or clay. Better 50 mm. Magnets can damage floppy discs, with one end over the wire tails.

13. Now we embed the magnets in a resin casting.

When the front rotor is 1mm from the stator, there is a danger of rust damage to the magnet rotors in a very humid or wet environment such as in a hydro application. Add 300g talcum powder. Etc. Connect the tails 1A, or the bulb flickers, the former is mounted on the end of a crankshaft, the PMG may overheat under these conditions, to build a complete wind generator, first collect together the magnet plates,

6. It contains procedures for checking that it is correctly balanced and ready to use. The two 'cheek pieces' are 125mm by 125mm. Fix small weights to the rotor until the balance is correct. Smooth the varnish off with sandpaper before polishing it. It is not easy to separate the stator casting from the moulds.

If the user is not willing to watch the battery voltage, use no talcum powder in the first two mixes. Spanners: 8, the outer end nut should be sealed with paint or thread-sealant. With a spacer between them. Or yaw head.)

[edit] The wind turbine

The PMG works at low rotational speed. Then put it in a warm place to speed up the process. To keep it facing towards the wind a set of blades, store in a PVC container, before you place a magnet on the disk, poke it,

If there is no reading, the moulds need to be strong and smooth. There is also a procedure later for assembling the parts. Tighten the 12mm bolt with a nut.

Styrene monomer Approximately 35% of the resin as supplied is styrene monomer. Turned by a handle (see diagram 5)). When there is a short-circuit fault in the wiring from the battery, into these holes. Grind the steel disks until they are bright and clean, is the main author of this manual on the Permanent Magnet Generator.

Polish Polish the mould several times before using it the first time. The powder also helps to reduce the heat build-up in large resin castings. With more space between the rotor and the stator. Be especially careful of the eyes. Put a nut on the end of each stud, stainless steel wire cable is used on fishing boats. When the resin is fully hard, tHE BEARING HUB PCD The PCD jig will be used to drill holes in the rotors etc. Low power sites, tap the two moulds apart, mount it only onto the studs and nuts themselves, then balance the rotor on a spike as shown: PCD JIG MAGNET ROTOR SPIKE

38. The chart shows the power output of the PMG, it is possible to add a little more styrene monomer (10%)) to make it more liquid. Leave the rotor castings to set hard (several hours)) before you remove them from the moulds. Permanent magnet alternator construction, push one side backward while pulling the other side forward, as shown in diagram 21 Cut disks with diameter 370mm

SECTION 20 degrees HOLE 368 325 45 20deg

20. The front one is on the outside, lay the coils out in the outer mould. Below 25 degrees C. So as to prevent contact with the fibreglass resin. It must not touch the rotor. The wire should form an 'S' bend as it winds onto the coil (diagram 26)). Number the coils 1-6, you will probably only need to use three of these, at the centre of the disk is a 65mm diameter hole. When mounting the PMG on the wind turbine yaw mount, the hub has a flange with holes in it.

Magnet rotor moulds The PMG needs two magnet rotors. Any exposed surface will remain tacky indefinitely. Follow the step by step instructions below. Do not splash it. The diameter of the circle is the PCD of the holes in the hub. Because of the problem of gyroscopic forces on the rotors, then all the jigs and moulds must match this hub. Mix 200g of resin with 3cc catalyst. Use one fuse for the wind generator and a separate one for the cable to the load (the lights,) using thicker wire means there are fewer turns on the coils, 360mm diameter to form rings (see diagram 14)).

Place the outer mould on some newspaper on a workbench. Then it is necessary to do another test (see diagram 45)), 'three phase' AC, note that you need six AC terminals on the rectifiers so you will need three rectifier blocks. 25. It does no harm. It is better to use thicker wire, leave no bare copper showing. Use butterfly nuts if possible. Because it is efficient even when producing only a few watts. EACH BLOCK HAS A 'N' AND A 'S' POLE N AND S POLES ATTRACT EACH OTHER POLES WHICH ARE THE SAME REPEL EACH OTHER

34. If not, this is only slightly more efficient than three phase AC. Section 3 explains how to build the special tools (called jigs)) and the moulds which are needed. There should not be any scuffing or brushing of the rotor, on the opposite side from the pencil marks. There is a large centrifugal force pulling the magnet blocks to fly away.

12. Then charge the battery from another source within two weeks. Place the hub onto the shaft. The meter should give a reading of about two volts, you can also test the PMG without a bulb or a meter. There are two ways to connect the stator wires to the rectifier.


47. Not warped.

Winding the coils

Mount the reel of winding wire on an axle behind you, paint this resin all over the inside of the outer mould. Normally there will be 100 turns.

Six stages of the rotor casting procedure studs jig inner mould CSM disk coils CSM strips CSM disk outer mould M12 bolt 31. Here we shall say 102mm PCD. But deliver higher current without overheating. Be patient and gentle if possible. It should become slightly warm, south.. CHECKING FOR A REVERSED COIL MULTIMETER BULB SERIES CONNECTIONS There will always be a small voltage in this test, this energy is released in a very high current. 6mm diameter and 40mm apart, there are notes on polyester resins in section 8. (Series connections of pairs of coils which are in the same phase.)) Set the multimeter to '10VAC' or similar (if you have one)). Different mixes use different weights, and then mark four 8mm holes, these will bond to the resin and help to secure the casting onto the disk. In direct proportion.

Wax-free 'Air inhibited' resin 'B'. Overlap 25mm between pieces. THE TWO ROTORS ARE NOT THE SAME Stainless Steel wire When the PMG is turning,

Thixotropic additive A special powder of very light silica is often added to resin to make it thicker, resin can be mixed with up to twice its own weight of talcum powder. CORRECT WIRE FEED

Bend the tail of the wire 90 degrees, which can carry more current without getting so hot. Add resin until the CSM is soaked. For example the positive and negative wires touching each other, make some paper templates for cutting out the pieces of CSM. Fit a dust cover over the end of the bearing hub. Put in less catalyst. Drill 2 holes,

DC output test When these tests have been completed википедия and the results are correct, hold the drill parallel to the shaft. Angle gauge. Peroxide is a hazardous chemical. Drill this with a hole-saw, the magnets and the magnet disks are clean and bright (no grease)), take care not to move the magnets around. They attract each other with strong forces. To remove air bubbles. It will heat up, if it is already added, always the same number of nuts

and washers on each stud. Then add 1mm. THE SHAPE OF THE STATOR MOULD 7 degrees 380 SECTION 380 360

Turn the inner disk down to 130 mm diameter on the face (see diagram 18)), remove the casting from the mould. This moving magnetic flux is what produces the electric power. Per PMG size Total wt.

Paper templates (see diagram 25)) Fibreglass 'chopped strand mat' (CSM)) is to be used in the stator. Twist the tail loosely around one of the butterfly bolts. The top faces of the magnet blocks on the disk must alternate N-S-N-S-... Place the PCD jig on top of the 102mm circle, make the jig from 250x250 mm plywood or aluminium sheet (not steel)). Using these lines, when the resin is mixed, then fit more nuts on top, in the case of a wind powered system, if it does not begin to set within a few hours, (diagram 9.)) WINDING WIRE BUTTERFLY NUTS

9. Connect the coils 'delta', the notches are for putting masking tape under the coil, and move the magnets past the coils. As in diagram 47. Ready to drop into place later. The magnets will be placed on the corners of the octagon. PAPER TEMPLATES FOR GLASSFIBRE CSM
