I have just acquired a DC motor from a treadmill. The specs on this motor are: 3200RPM 32.5amps 90VDC I'm wondering how good this motor will be for a wind generator. I'm new to the boards and building wind generators and would greatly appreciate some input from people who know what they are doing. One of my questions is how do you keep the voltage constant while still getting more Watt's from it. Also wonder what sort of wattage I can expect out of this motor at different RPM's. Also wonder what wind speeds would be required to push this motor to sufficient rpms to generate at least 12volts.
