The invention relates to a composite excitation amorphous alloy axial reluctance motor, wherein the stator core is a ring-shaped modular amorphous alloy stator core composed of 6*n modules, n is a positive integer, and each module is composed of a permanent magnet on the circumferential side of a stator yoke part, a stator tooth part and a stator yoke part, and the polarities of adjacent permanentmagnets are opposite; The stator core has 6*n stator teeth on its side surface, 6*n open slots, 6*n permanent magnet poles, a rotor on the stator teeth side, 5*n ferromagnetic poles on the rotor yokepart close to the stator side, and windings wound on the stator teeth part; The stator and the rotor are located in the casing, the stator is fixed on the casing, and the rotor is fixed on the rotating shaft of the motor through the rotor bracket. The composite excitation amorphous alloy axial reluctance motor has the advantages of simple manufacture, low loss, high power density and wide range of weak magnetic field expansion speed.
