150V wind turbine motor

I wonder if I can use a 150VDC PM wind turbine motor on 12V or 24V battery bank without harming the battery? Thanks for the feedback.

    You can... Assuming the battery is capable of absorbing the current (i.e., battery is around 8-20x the current output of the motor--I.e., a 10 amp motor * 10 would be a 100 AH battery bank) and you have a diversion/dump charge controller that turns on a dump load (typically a resistance heater) to keep the battery from over charging.

    One issue with running a high voltage PWM motor at 1/10th its output voltage is that you also get 1/10th the capable power of the motor (i.e., 10a*150v=1,500watts vs 10a*15v=150watts).

    If you want to make a DIY wind turbine, there is lots of information and a forum over here:

    I run 180 volt PMDC motors for 12 volt charging,these are 1725 rpm 8amp motors and do a good job.
