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.

    一种谐波减速器轮毂电机,包括轮毂外壳、两极外转子无刷永磁直流电机、滑轮式谐波发生器、柔性齿圈、刚性齿圈、轮毂端盖、轮毂轴、联轴盘和联轴支架,柔性齿圈左、右两端的方波形齿牙与左、右联轴盘的方波形外齿牙之间的啮合,使柔性齿圈成为不旋转的活动定子,两极外转子无刷永磁直流电机带动滑轮式谐波发生器旋转,使椭圆形柔性齿圈发生波动变形,柔性齿圈是簿的圆筒形,波动变形时产生的阻力小,谐波减速器轮毂电机的减速比很大,使刚性齿圈的低速扭矩增大,两极外转子无刷永磁直流电机的转速高、功率密度大,机电一体化的谐波减速器轮毂电机体积小、重量轻、效率高、结构简单,整体零件数少,可以应用于机器人的动力。
