A Synchronous Motor is an AC electric motor in which the speed of the rotor is the same as that of the revolving field in the machine. The synchronous motor runs at synchronous speed (i.e, Ns= 120f/P). It is to be noted, that the synchronous motor is a 3-phase motor and its frequency remains constant due to which it obtain …
