Body

Hello Mick and Interested,

I mechanically coupled an asynchronous motor with a 3-phase frequency inverter to the synchronous BLDC to bring it to synchronous speed and simultaneously operate the BLDC in a Rotoverterm mode via a Variac. As the BLDC immediately acts as a generator, the power increases immensely.

In a 1-phase inverter I have freewheeling diodes which redirect the energy in the DC link.

I have to admit the line resistance is very very low even with a wire of the multi-filament winding. I try again to wire all in series to maximum impedance.

Incidentally, only 4 separate windings per phase, I have always led out 2 wires together to one at that time.

regards

Sven
