A Homemade Alternator in a Wooden Frame
You can constitute a clean Permanent Solenoid (PM) alternator with dispassionate a sporadic items. This is an estimable design for a student to memorize approximately electricity and motors. By later these picnic steps, you Testament own a working PM alternator that you can benefit to recharge batteries or drop dwarf electronics projects.
Instructions
1. Catch a coffee can lid and hint the rotor extent in the centre. Grasp the CD against the rotor perpendicular to the Engine and evaluation that you keep it directly centred. Bring about not attach the disc--lay it Apartment lodgings on your duty surface.
2. Receipts your magnets and arrange them on all sides of the CD quite evenly spaced apart. Nowadays turn the magnets so that the Perch of Everyone magnetite alternates with the Perch of its neighbour. Settle a inconsiderable Blop of glue on the metal CD near the border, and put your fundamental electromagnet. The wrinkle of your magnet should be flush with the wrinkle of the CD. Let the glue dry so the magnetite is firmly held in district.
Booty your shim information and experiment with many layers of shims until you are confident that provided you were to mastery the shims against the front magnetite you placed and then situate down the next magnet, that you could repeat that process until all Fourteen magnets are placed on the disc evenly spaced. When you are sure you have the right amount of shims to do this, glue remainder of the magnets around the edge of the rim. You can use a glue accelerator to speed the process. Make sure the poles remain in their alternating position.
3. Glue the disc to the rotor, or use several small, strong magnets to attach it. You can turn the motor on and test to see that the disc will remain attached to the rotor as the engine turns.
4. Take your small wood frame and mounting hardware and mount your motor to the center so the rotor can spin the magnet disc freely. Make sure you leave both ends of the wire free, and strip the covering off them--this will be how you connect the coils.Once you have your coils, drip superglue onto them and let this dry.6. Take your small block of wood and mount your first coil by gluing it flat to the wood.
Your frame should be large enough that you can place your wooden blocks near the spinning disc but not be touched by it. The frame can either lie flat, or you can make a stand to hold it upright.5. Using the hand-held coil winder, wind two coils of about Four hundred turns each of the magnetic wire.
Place the block onto your wood frame. You will want to make sure to test that your magnet wheel can spin freely over the coil; the most space you want between your magnet and coil is about 1/8 of an inch. When you are sure that it is positioned correctly, glue the block onto the frame.
Glue your second coil to a block of wood. Turn the magnet wheel so one of the magnets is centered directly over the first coil. Hold the wheel firmly in place and glue the second block into position so it is centered directly below a magnet. It does not matter where on the wheel you place your second coil.
7. Connect both coils together by taking one wire from each and splicing it together. You can attach the second wire to the object that will receive the electricity generated by your alternator. For now, take your multimeter and attach it to the free wires, get a reading of the voltage being generated and experiment with the placement of the coils until you are satisfied with their output.
