A magnetic flux switching hub motor having a permanent magnet rotor, includes: a wheel rim, a stator core, an armature winding which is wound on the stator core, and a plurality of rotor units, wherein rotor units are fixed inside the wheel rim, and a rotor unit comprises a permanent magnet and rotor cores which are arranged on two sides of the permanent magnet, the magnetization direction of the permanent magnet being tangential magnetization, and a magnetization direction of each permanent magnet being the same. The motor has the advantages of being high power, and having strong saturation and overload resistance, high reluctance torque, good flux-weakening performance, a broad speed regulation range, a high degree of manufacturing integration, suitability for modular manufacturing processes, and the like.
