The invention discloses a centrally-mounted motor and an electric bicycle, the centrally-mounted motor comprises a shell, a torque sensing pedal spindle, a power output part, a motor and a multi-stage planetary reducing mechanism, and the torque sensing pedal spindle is rotatably connected to the shell; the torque sensing pedal spindle is connected to the power output piece through a first overrun clutch; the motor is mounted on the shell; the multi-stage planetary speed reducing mechanism is connected to the output end of the motor and connected to the power output piece through a second overrun clutch. By adopting the multi-stage planetary reducing mechanism, the shape of the middle motor is regular, the whole appearance is centrosymmetric about the moment sensing pedal spindle, the structure is compact, the reduction ratio is large, and the appearance requirement of the whole vehicle is met. And the torque sensing pedal spindle and the multi-stage planetary speed reducing mechanism are connected to the power output part through the first overrun clutch and the second overrun clutch respectively, so that manpower and motor power can be input at the same time and do not influence each other when being input independently.

    本发明公开了一种中置电机和电动自行车,其中中置电机,包括外壳、力矩感应脚踏轴、动力输出件、电机和多级行星减速机构,所述力矩感应脚踏轴转动连接于所述外壳;所述力矩感应脚踏轴通过第一超越离合器连接于所述动力输出件;所述电机安装于所述外壳;所述多级行星减速机构连接于所述电机的输出端,并通过第二超越离合器连接于所述动力输出件。通过采用多级行星减速机构,使得中置电机形状规则,外观整体以力矩感应脚踏轴中心对称,结构紧凑,减速比大,满足整车外观需求。并且力矩感应脚踏轴和多级行星减速机构分别通过第一超越离合器和第二超越离合器连接于动力输出件,使得人力和电机动力可同时输入,独立分别输入时相互也没有影响。
