They are pulsing the power with switching relays , so not 3 cycles just pulses at certain intervals to control the speed of the rotor , still using 3 windings in the motor some may have 3/6/9/12 poles ina stator to achieve the power outputThis is probably my ignorance but how can you have multi-phase DC? I thought the "phase" part required the wave effect of AC.
