The invention relates to a driving motor which comprises a center shaft, a rotor assembly, a planetary transmission mechanism, a cycloid speed reducing mechanism, a clutch mechanism and an outer hub. The outer hub is connected with the cycloid speed reducing mechanism through the clutch mechanism; when the rotor assembly rotates, the planetary transmission mechanism is driven to rotate, so that the planetary transmission mechanism drives the cycloid speed reducing mechanism to rotate, and the outer hub is driven to rotate in the forward direction relative to the center shaft. The motor adopts two-stage speed reduction of the planetary transmission mechanism and the cycloid speed reduction mechanism, meanwhile, the speed reduction mode from the rotor assembly to the planetary transmission mechanism and then to the cycloid speed reduction mechanism is adopted, the speed reduction mechanism is stable, transmission stability of the planetary transmission mechanism can be guaranteed, stable swing of the cycloid speed reduction mechanism can also be guaranteed, clearance rotation is prevented, and abrasion is reduced; two-stage speed reduction enables the driving motor to be large in torque and strong in supporting capacity and bearing capacity, the two-stage speed reduction structure is compact, the overall size of the motor is small, and the motor can be suitable for frames of most bicycles.

    本发明涉及一种驱动电机,包括中心轴、转子组件、行星传动机构、摆线减速机构、离合机构以及外轮毂;外轮毂通过离合机构与摆线减速机构连接;当转子组件转动时带动行星传动机构转动,使得行星传动机构带动摆线减速机构转动,从而带动外轮毂相对中心轴正向转动;电机采用行星传动机构和摆线减速机构两级减速,同时是先采用转子组件到行星传动机构再到摆线减速机构的减速方式,减速机构稳定,既可以保证行星传动机构传动的稳定,也可以保证摆线减速机构稳定摆动,防止虚位转动,减少磨损,两级减速使得驱动电机扭矩大,支撑能力和承载能力强,并且两级减速结构紧凑,电机整体体积小,可以合适绝大部分自行车的车架。
