Electric motor - Wikipedia

The main types are DC motors and AC motors, the former increasingly being displaced by the latter [citation needed] AC electric motors are either asynchronous or synchronous Once started, a synchronous motor requires synchronism with the moving magnetic field's synchronous speed for all normal torque conditions

AC induction motors | How AC motors work - Explain that Stuff

Jan 06, 2019· Induction motors in practice What controls the speed of an AC motor? In synchronous AC motors, the rotor turns at exactly the same speed as the rotating magnetic field; in an induction motor, the rotor always turns at a lower speed than the field, making it an example of what's called an asynchronous AC motorThe theoretical speed of the rotor in an induction motor depends on the ,
