2018622 · It presents the most elementary principles of operation of synchronous machines. The chapter describes the following three important laws of electromagnetism: Faraday's law of electromagnetic induction; Ampere-Biot-Savart's law of electromagnetic-induced forces; and Lenz's Law of action and reaction.

view moreThe permanent magnet synchronous motor working principle is similar to the synchronous motor. It depends on the rotating magnetic field that generates electromotive force at synchronous speed. When the stator winding is energized by giving the 3-phase supply, a rotating magnetic field is created in between the air gaps.
