Motor/generator Question

post #1 of 2
Thread Starter 

Hi, I'm very new to all of this. My goal is to make a wind generator. From the little reading I've done, it sounds like a permanent magnet motor is a good power source. I plan to use the motor off of an old tread mill. The motor I have is a United Technologies Automotive permanent magnet DC motor, model 68616.  It's 2.5 HP, 130VDC, 17.2 amps             7099 RPM.    My first question is if this is a good choice for a small wind turbine. My second question is, how do I check to see if this motor is still good? When I spin it by hand I can get about 4 volts and 1 amp.  The tread mill I got it out of was discarded because it didn't work. Thanks, Smitty

This sounds like such a cool project Smitty!  I seem to recall some kind of publication, I think it was called Lindsay, I haven't seen it for some time.  Lot's of good home-built info.  Would you need some kind of power transmission gear ratio too? 

 

I remember when i was a kid i would tinker with generation with DC motors.  Once made a dc motor mount to my bike so the rubber would spin the motor.  Not a real bright light, but it worked!
