...mentioned in another post, and it should do a good job of running your three phase motor. You will have to allow for the load current of the rotary converter, plus the load current of the three phase motor(s) that you plan to run on the generator when sizing ...three phase from single phase, you will have very little starting surge on the system, but the voltage regulation circuits ...
