The stator and rotor comprise the 3-phase AC induction motors. During operation, a current is applied through the stator, which induces a magnetic field and leads to the rotation of the rotor. The rotational speed of the shaft and the applied torque depends on the operating frequency and the number of pole pairs in the motor's windings.

Asynchronous (induction) motors can be further categorized into two different types based on their construction: the squirrel cage induction motor and the wound rotor induction motor. Synchronous and asynchronous motors are both 3-phase motors, however, they operate on different principles. Images adapted and used …

The three phase induction motor works on the principle of electromagnetic induction. When a three-phase supply is given to three-phase winding of the motor, a magnetic field is produced which rotates at synchronous speed. The rotating flux passes through the air gap and cuts the rotor conductors which are at rest.
