Abstract
An AC motor with a reduction mechanism is disclosed. The AC motor has a stator unit, a rotor unit, and a reduction transmission unit. An axial space of the AC motor can be substantially reduced by providing the reduction transmission unit directly built in the AC motor, and a path of the power transmission between the rotor unit and an output shaft can be reduced, so that the loss of the mechanical energy can be lowered.
