A typical AC motor consists of two parts:An outside stationary stator having coils supplied with AC current to produce a rotating magnetic field, and;An inside rotor attached to the output shaft that is given a torque by the rotating field.There are two fundamental types of AC motor, depending on the type of rotor used:The synchronous motor, which rotates exactly at the supply frequency or a sub -multiple of the supply frequency, and;The induction motor, which turns slightly slower, and typically (though not necessarily always) takes the form of the squirrel cage motor
