The invention provides a centrally-mounted motor used for a power-assisted electric bicycle system, the centrally-mounted motor can refit a common bicycle into an electric power-assisted bicycle, the centrally-mounted motor comprises an electric power-assisted system composed of a motor, a primary reduction gear, a controller, a torque sensor, a pedaling frequency sensor, an instrument, a battery and the like, and a traditional bicycle is changed into the electric power-assisted bicycle. Wherein the speed reduction system of the middle motor only has one stage, and is integrated with a pedaling frequency sensor, a torque sensor and a controller. A center motor is installed through a bottom bracket (305) of a bicycle, a center shaft (101) is installed in a tubular bearing chamber on a center motor shell (205), a torque sensor, a pedaling frequency sensor, a clutch and a primary gear driven wheel are installed on one side of the center shaft, and the motor (306) transmits torque through a rotor gear shaft.

    本发明提供了一种中置电机,用于助力电动自行车系统,该中置电机是可以将普通自行车改装为电助力自行车,其包括电机,一级减速齿轮,控制器,力矩传感器,踏频传感器、仪表、电池等组成电助力系统,使传统自行车变身为电助力自行车。其中,所述的中置电机的减速系统只有一级,并且集成踏频传感器,力矩传感器,控制器。本发明利用自行车的五通(305)安装中置电机,中置电机机壳(205)上的一个管状轴承室内安装中轴(101),中轴的一侧安装有力矩传感器,踏频传感器、离合器及一级齿轮被动轮,电机(306)通过转子齿轮轴传递扭矩。
