The invention discloses a shade pole type single-phase alternating current asynchronous motor with low vibration torque, and particularly relates to a shade pole type composite single-phase alternating current asynchronous motor. The shade pole type single-phase alternating current asynchronous motor with low vibration torque comprises a rear end cover, a rear bearing, a machine seat, a 1# stator core, a 1# rotor core, a 1# stator winding, a 2# stator winding, a 2# stator core, a 2# rotor core, a 2# stator winding, a front end cover, a front bearing, a rotation shaft, a 1# rotor winding, a 2# rotor winding and a phase-shift capacitor. The shade pole type composite single-phase alternating current asynchronous motor enables the vibration torque generated by two sets of shade pole type motors to right differ by an electrical angle of 180 degrees, and achieves the purpose of restraining the vibration torque through mutual compensation of positive and negative components of the vibration torque. If two generated vibration torque amplitude values are the same, the vibration torque is completely restrained. Besides, due to the fact that a branch circuit and a home circuit of a 2# motor with a series capacitor are capacitive, the power factor of the formed composite motor is higher than the power factors of the two original motors.
