Your getting there slowly but surely. You say that your going with a PMA. Is that what you guys find works best for low speed applications. I see on some wind generator sites they speak highly of servo motors as generators. Have you any experience with them you could share.

Hi I will be test two PMAs. A hoverboard motor and a F&P washing machine motor. Both are three phase. At 600 RPM the hoverboard will produce about 10 amps at 12 volts and the F&P will produce about 50 watts at about 180 RPM. I will use a PWM circuit to limit the back EMF, copper loss, (I squared R) loss. Thanks for another option.
