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.

Can u explain : how capacitor act when the supply is given is a.c and d.c. I know that when d.c supply is given then the capacitor charges and becomes open circuited. But please say about when a.c is given. I have seen that when a.c supply is given ,it charges and discharges, But when we plug in capacitor to our daily supply and take it out ,then we join those wires spark will appear,which seems charge is present ,but when a.c is given it should charge and discharge
