The invention discloses a motor comprising a housing, a shaft, a stator component fixed inside the housing, and a rotor component synchronously rotating with the shaft. The stator component and the rotor component are in serial distribution along the axial direction. The housing is internally equipped with a magnetic modulation component which surrounds the stator component and the rotor component, and there is a gap between the magnetic modulation component and the stator component and a gap between the magnetic modulation component and the rotor component. The magnetic modulation component is used for modulating an armature magnetic field produced after the stator component is electrified and producing a harmonic magnetic field driving the shaft at the gap outside the rotor component. The invention further discloses an elevator tractor with the motor. Low speed and high torque are achieved by using the harmonic magnetic field to transmit energy based on the permanent-magnet gear magnetic field modulation principle. Meanwhile, by adoption of a double-permanent magnet excitation mode, the motor and the elevator tractor have the characteristics of high torque density and high efficiency.
