Introduction of Induction Motor The most basic feature of an Induction motor is its self starting mechanism. Due to the rotating magnetic field, an emf is induced in the rotor, because of which current starts flowing in the rotor. As per the Lenz law, the rotor will start rotating in a direction so as to … Read more
