How does the field winding receive current
WebApr 4, 2024 · The large current through the winding produces a strong magnetic field. This strong magnetic field gives high torque to the armature shaft, thus exerting the spinning action of the armature. Hence the motor starts rotating at its … WebJan 11, 2024 · The stator windings also connect to the ac power as in an induction motor. The stator magnetic field rotates in sync with the line frequency. The rotor winding in a synchronous motor may receive current in a variety of ways, but usually not by induction (except in some designs, only to provide start-up torque).
