The invention discloses a three-speed centrally-mounted motor capable of automatically shifting gears, and relates to the field of centrally-mounted motors. The technical scheme comprises a center-shaft mechanism and a power-assisted driving mechanism; the center-shaft mechanism comprises a center shaft, and an input transmission assembly, a first one-way clutch assembly, a centrifugal clutch assembly and an output transmission assembly are arranged on the center shaft. The input transmission assembly comprises a pedal power input unit which is connected with the middle shaft to receive pedal input rotating speed, and a power-assisted input unit which is connected with the power-assisted driving mechanism to receive power-assisted input rotating speed; the center-shaft mechanism comprises the following transmission paths from an input transmission assembly and a first one-way clutch assembly to an output transmission assembly. And the input transmission assembly, the centrifugal clutch assembly and the output transmission assembly are connected. Automatic gear shifting can be achieved according to the rotating speed, the riding experience and comfort can be improved, the overall size of the motor can be reduced, and whole vehicle installation is facilitated.
