Synchronous motor: Stator poles rotate at the synchronous speed (Ns) when fed with a three phase supply.The rotor is fed with a DC supply. The rotor needs to be rotated at a speed near to the synchronous speed during starting. If done so, the rotor poles get magnetically coupled with the rotating stator poles, and thus the rotor starts rotating at the synchronous speed.
