The invention discloses a middle motor for an electric moped. The middle motor is used for outputting torque to a driving wheel of the electric moped. The middle motor comprises a seat body; a statoris fixedly mounted on the seat body; a rotor shaft and a main shaft are rotatably mounted on the seat body; the rotor shaft is in transmission relationship with a power output unit; a rotor is arranged on the rotor shaft; a first one-way transmission unit is arranged between the rotor shaft and the rotor; the main shaft is connected with the power output unit through a second one-way transmissionunit. According to the middle motor for the electric moped, the first one-way transmission unit and the second one-way transmission unit are arranged, so that the actions of the rotor and the main shaft on the power output unit can be independent from each other, three power modes of an electric mode, a manpower mode and a power-assisted mode can be realized; electric energy loss or kinetic energyinput by a user in the electric mode and the manpower mode is small, and an energy conversion rate is high.

    本发明公开了一种电助力车用中置电机,用于向电助力车的驱动轮输出扭矩,其包括座体;所述座体上固定安装有定子,且所述座体上转动安装有转子轴与主轴;所述转子轴与动力输出单元具有传动关系,且所述转子轴上具备转子,所述转子轴与所述转子之间设置有第一单向传动单元;所述主轴通过第二单向传动单元连接所述动力输出单元。本发明的电助力车用中置电机通过设置第一单向传动单元与第二单向传动单元,可使得转子以及主轴两者对动力输出单元的作用相互独立,可实现电动模式、人力模式以及助力模式三种动力模式,且电动模式与人力模式下电能或用户输入的动能损耗小,能量转化率高。
