A synchronous motor is an AC motor in which the rotation of the rotor is synchronized with the frequency of the supply current. That is, the period of rotation of the rotor is equal to the rotating magnetic field of the machine in which it is placed. In this article, we will introduce synchronous motor working principle. The working principle of synchronous motor is magnetic lock. When two different magnetic poles meet, a huge pull-off force is created between the two magnetic poles.
