What is the principle of 3 phase induction motor? Quora

Three phase induction motor works on Faraday's law of electromagnetic induction. the secondary winding goes on the rotor, which can either be wound with wire, or have metal conductor bars. If a bar construction is used, it is called a squirrel cage, and if it is wound, it is called a wound induction motor. 3-phase induction motors are
