What is the principle of operation of three phase squirrel cage induction motar?

three phase induction motor is like a rotating transformer, works on the principle of faraday's law of electromagnetic induction. when ever three phase supply is given rotating magnetic field is produced (rotating magnetic field is produced because current flowing through each phase is delayed 6.66mSec) and the stationary conductor (rotor) is cut by the rotating magnatic field so emf is induced in the conductor (rotor) since rotor is short circuited current flows and this current produces magnatic field. magnatic field produced by the rotor interacts with the rotating magnatic field. this interaction of fields produces movement in the conductor(rotor)(since it is allowed to rotate).
