Induction motor
In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding. ... Induction motors are referred to as 'asynchronous motors' because they operate at a speed less than their synchronous speed.
