Synchronous Motor Excitation

Synchronous Motor Excitation Prior to understanding this synchronous motor excitation, it should be remembered that any electromagnetic device must draw a magnetizing current from the AC source to produce the required working flux. This magnetizing current lags by almost 90o to the supply voltage. I
