The utility model relates to a harmonic reducer hub motor, which comprises a hub shell, a two-pole outer rotor brushless permanent magnet direct current motor, a pulley type harmonic generator, a flexible gear ring, a rigid gear ring, a hub end cover, a hub shaft, a coupling disc and a coupling support, wherein square waveform teeth at the right and left sides of the flexible gear ring are meshedwith the square waveform outer teeth of the right and left coupling plates, the flexible gear right is made to be non-rotatable movable stator, the two-pole outer rotor brushless permanent magnet direct current motor drives the pulley type harmonic generator to rotate, so that the oval flexible gear ring is subjected to fluctuation deformation, the flexible gear ring is in a thin cylinder shape, resistance generated during fluctuation deformation is small, and the reduction ratio of the harmonic reducer hub motor is very large, so the low speed torque of the rigid gear ring is made to increase. The two-pole outer rotor brushless permanent magnet direct-current motor is high in rotating speed and high in power density, and the mechatronics harmonic speed reducer hub motor is small in size,light in weight, high in efficiency, simple in structure, small in number of overall parts and capable of being applied to power of a robot.
