Body

It is a Siemens 1 FT 3 phase motor from the industry. The 3 phases are led out multifilar. From each phase I have created 6 phases that I can connect to extremely high impedance or too low. I had already thought about the engine via another via V-belt to synchronous speed to bring and then operate as a Rotoverter Primemover or test. Accurate characteristics I would have to look up to 400v Regards Sven

Sven,

What size and voltage is your motor?

How did you rewire it?

How many phases is it?


As you know a synchronous motor is most likely to use a VFD sine controller while the BLDC is a pulse controller.   I think a synchronous AC can run with an BLDC controller but not as well as the controller is pulsed rather than sine.
We used audio amplifiers and frequency gens to control low paoer single phase synch motors in the past.
