An induction motor is an electric motor that uses alternating current (AC) to produce rotational motion. It consists of a stator, which is a stationary outer shell, and a rotor, which is a rotating inner shell. The stator has a winding of conductors that carries alternating current, which creates a magnetic field. The rotor has a winding of conductors or a cage of conductive material that is short-circuited at the ends.
