Hi,
I have some scrap motors, and want to use it as a wind generator to charge a 12V battery bank. It's a permanent magnet 3 phase AC motor.
In it's application it is driven by sinusoidal PWM with a 3 phase 12V inverter, and is rated for a current of about 100A.
It has the inverter mounted on the motor, and I wanted to use it as a 3 phase rectifier using the body diodes of the fets.
I don't know a great deal about motors, but other such projects I've seen, people are using all sorts of different motors.
Without trying it out with blades attached, how can I estimate how much power output I'll be able to get from it?
I've read that voltage generated is proportional to rpm, w, so V = kw. Can I say that the output power will be V^2 / R, where R is the resistance of a motor winding?
I'm a bit lost with motors...
