The input supply is given to the 3 phase stator windings. Due to this the rotating magnetic field is created. This rotating magnetic field cuts the rotor bars. Due to this emf is developed in the rotor bars according to Faraday's law. This emf causes current to flow in rotor bars which interacts with rotating magnetic field of stator. Hence force is experienced
by rotor and it rotates.
