The invention provides an electric vehicle hybrid excitation hub motor which is composed of a shaft, a hub, rotor poles, stator poles, two sets of armature windings, stator iron cores, excitation windings, permanent magnets and a hub cap. The fan-shaped stator iron cores are fixed in the middle of the shaft in a back-to-back way. The two sides of the stator iron cores are provided with the protruding stator poles. The rotor poles are fixed on the internal walls of the two end surfaces of the hub. One permanent magnet is clamped between every two stator iron cores which are aligned in a circumferential direction. A groove is arranged between the two opposite stator iron cores and used for embedded arrangement of the excitation windings. Each stator pole is provided with the armature windings in a winding way. Integration of the hub and a driving motor is effectively realized by the technology so that the size and the weight of a driving system can be reduced; the rotor has no permanent magnet or excitation winding so that the possibility of demagnetization of the permanent magnets caused by impact can be reduced; a permanent magnetic field can be enhanced by an electric excitation magnetic field at low speed so that high-torque output can be realized; and the permanent magnetic field can also be weakened at high speed so that high-speed weak magnetic control can be realized.
