An amorphous alloy axial flux motor with wide field weakening, expanded speed and low rotor loss. It includes a double stator structure and a single rotor structure. The rotor structure is located in the middle of the two stator structures; the stator includes a winding of amorphous alloy material. The stator yoke and the stator teeth; the stator yoke is directly in contact with the end cover; the stator yoke and the stator teeth together form the stator core; the end covers at both ends of the casing are equipped with circumferential disc-shaped water channels; double-layer distributed armature windings Embedded in the stator core; the rotor structure is a single-disk structure, in which the number of permanent magnets and soft magnetic poles are equal; the soft magnetic poles are specifically low-conductivity SMC soft magnetic poles; the permanent magnets are specifically sintered neodymium iron boron permanent magnets and both sides Bonded neodymium iron boron permanent magnets with low conductivity; the rotor bracket is sleeved on the motor shaft; it has a larger inductance of the AC-DC shaft, lower rotor loss, and can make full use of the unequal inductance of the axial-flux motor. The reluctance torque has a wider range of field weakening.
