DC Wind Turbine Motors on eBay – BEWARE

[Daox]

This is good info to know if you're planning on putting together a wind turbine. As usual, you gotta know what you are looking for.

Pay attention to the maximum RPMs of the motor. You want a motor with the best voltage output and the LOWEST RPMs. Try to get a motor that will produce 1 volt for every 25 rpm. If a motor is rated as 130VDC with a top RPM of 5100, then divide 5100 by 130 = 39.2 … you get 1 volt output for every 39.2 rpm. This motor will not produce enough voltage to charge a 12V battery (15-16V is required) until you get very strong winds.
