The invention provides an electric motorcycle power system which comprises a motor shell and a controller shell, the controller shell is located on one side of the motor shell, an output shaft is arranged at one end of the motor shell, and the other end of the motor shell and the end face of the controller shell are coplanar and form an air cooling outer vertical plate. A sensor mounting cavity is formed in the end, located on the air-cooling outer vertical plate, of the motor shell and located between the air-cooling outer vertical plate and a stator cavity formed in the motor shell. Therefore, the air-cooling outer vertical plate can cool the motor and the controller and also can cool the sensor assembly in the sensor mounting cavity, so that normal operation of the sensor assembly is effectively ensured, and the normal operation of the sensor assembly is prevented from being affected by heat generated during large-load operation of the motor.
本发明提供一种电摩动力系统,包括电机壳体和控制器壳体,所述控制器壳体位于所述电机壳体的一侧,所述电机壳体的一端设置有输出轴,所述电机壳体的另一端与所述控制器壳体的端面共面并形成风冷外立板,所述电机壳体位于所述风冷外立板的一端设有传感器安装腔,所述传感器安装腔位于所述风冷外立板和所述电机壳体内部形成的定子腔之间。这使得风冷外立板在对电机和控制器冷却的同时还可以对传感器安装腔内的传感器组件进行散热,从而有效确保传感器组件的正常运行,避免电机大负载运行时产生的热量影响传感器组件的正常运行。
