The invention discloses a hub motor with a heat dissipation device. The hub motor solves the problems that a heat exchange motor on an existing electric vehicle is relatively complex in structure and inconvenient to assemble and arrange. According to the hub motor, the heat dissipation device structurally comprises a fan rotationally arranged in a hub, the fan is located on one end side of a rotor in a mounting cavity, the fan is provided with an air pushing part and a coupling part, the air pushing part is arranged on the periphery of the coupling part, and the coupling part rotates in the circumferential direction and is axially and fixedly connected to a motor shaft in a sleeving mode; a plurality of starting magnets are arranged at one end part of the rotor, the starting magnets are uniformly distributed along the circumferential direction of the rotor, and the end parts at the same side of two adjacent starting magnets are arranged in a manner of opposite polarities; a plurality of driving magnets are arranged on the coupling part, the driving magnets are uniformly distributed along the circumferential direction of the rotor, and the end parts on the same side of every two adjacent driving magnets are arranged in a manner of opposite polarities; and the driving magnets and the starting magnets are spaced in the axial direction of the rotor, and the number of the driving magnets is smaller than that of the starting magnets.
本发明公开了一种带散热装置的轮毂电机，解决了现有电动车上换热电机结构相对较为复杂、不便装配设置的问题。本轮毂电机中，散热装置的结构包括在轮毂内转动地设有风扇，风扇在安装腔内位于转子的一端侧，风扇具有推风部和轴联部，推风部设置在轴联部的外周，轴联部周向转动轴向固定地套接在电机轴上；在转子一端部设有若干启动磁铁，这些启动磁铁沿转子周向均布，相邻两启动磁铁的同侧端部以极性相反的方式布置；在轴联部上设有若干驱动磁铁，这些驱动磁铁沿转子周向均布，相邻两驱动磁铁的同侧端部以极性相反的方式布置；驱动磁铁和启动磁铁在转子轴向上具有间隔，驱动磁铁的数量少于启动磁铁的数量。
