I see. Its a 120 volt 60 Hz single phase input that feeds a a small inverter unit that drive the motor. Its a mix and match label. Its single phase feed but an actual three phase motor that runs on 120 volt three phase power produced by the little variable frequency drive unit.
I have something similar that came out an odd tread mill. Its a three phase motor, non PM type, but the original mill it came from labels it as a single phase powered motor system.
As far as using it as a PM alternator for a wind generator it should work just fine but your total amps output still cant be ran continuously over the single phase input rating the unit originally had so 10 amps is about all you are going to see from it at best without burning it out. Short overloads will be fine but not extended runs.
