When a circuit is connected then current in the coils creates magnetic forces that interact with the magnets to oppose the motion of the blades. Current manifests itself as torque (resistance to turning). Voltage is proportional to speed. Voltage combined with current amounts to electrical energy being produced. "ith torque are the ingredients of the mechanical power you need to put in (using the blades) so as to get electrical power out. In both cases, power is measured in watts, and if sustained it will deliver energy in Watt-hours or kilowatt-hours.
The blades produce mechanical energy that is converted to electricity by the alternator. A powerful alternator will not help ifthere is not enough mechanical power. '- - I- - f- ~ ~ '- Voltage alone is not the same as power. If there is no external circuit connected to the coils, or if the voltage is too low for battery charging, the magnet rotors spin freely, because no energy is being converted. Under these conditions the blades can become noisy due to running faster than they are designed to run.
Build up the stack of nuts in the correct position before you assemble the alternator. J, nuts evenly against each other so that each slack is the same size. It is bard to do this when they are between magnet rotors because the magnets ",;11 grab the tools. to cases where the back of the hub is not nat then it may be necessary to grind off the corners of the nuts so that they do not put a bending load on the studs. SHAFt It is generally easier to build the allemator if the front magnet rotor is on NUT the front of the hub nange and can be mounted after the hub is on its bearings, but you can even put both disks on the back.
