One idea I heard was to make windmills with the rotor stator on the rim rather than have the generator at the centre. (As explained to me) the trade off is as follows: the bigger the windmill, the greater the structureal efficiency (more power per structure, the lower the required wind speed t

in order to maintain 60 hz at multiple rpm's, you need to generate dc, and use an inverter to get ac. not many types of ac motors can be used for ac generators. asynchronous motors can be IIRC. dc permanent magnet motors are interchangeable. Steve Spence Subscribe to the Renewable Energy Newsle

My understanding is that the some of the windings have to be "excited" before the other winding will incite a current. However, this is where my confusion comes in. I am interested to know how one wires up a motor to act like a generator. I'll do some "googling" Darryl McMahon wrote: >Martin,

Martin, my understanding is that any AC motor will generate if turned mechanically and the electrical circuit is made. However, I believe the frequency (e.g. 60 Hz) is very dependent on maintaining the rpm of the motor (now alternator) at the correct speed. Darryl McMahon To:
