External stator magnetic pole block form mixed excitation compound machine

External stator magnetic pole block form mixed excitation compound machine relates to mixed excitation compound machine field. The problem of traditional mixed excitation motor output torque little is solved. In the motor, the magnet adjustment ring rotor lies in between internal stator and the external stator, fixes through the support and serves at one of magnet adjustment ring rotor output shaft, all separates through radial air gap between magnet adjustment ring rotor and internal stator and the external stator, the internal stator is fixed on the internal stator output shaft, and the support of the one end of internal stator output shaft and magnet adjustment ring rotor passes through the bearing and rotates and be connected, the winding has armature winding on the internal stator, and permanent magnetism external stator and electric excitation external stator are fixed side by side on motor shell's interior round surface, and separate through the axial air gap between permanent magnetism external stator and the electric excitation external stator, stator core's interior circle surface along a circumferencial direction equipartition n permanent magnet outside the permanent magnetism, and the interior round surface of electric excitation external stator is provided with a 2n stator tooth, and it has an excitation winding all to twine on stator tooth at the every interval, realizes big torque output.
