Problems solved by technology

[0003] In order to pursue the high power torque density, high efficiency and controllable effect of the magnetic field of the motor, many researchers have proposed different types of topological structures in the form of mixed excitation to solve the problem that the magnetic field of the traditional permanent magnet synchronous motor is difficult to adjust and is not conducive to the weakening of the magnetic field. and other issues, but there are still defects in varying degrees:
However, its permanent magnet is located in the stator, and the assembled stator core increases the difficulty of process and assembly, and the electric excitation magnetic circuit passes through the permanent magnet, which increases the copper loss of the excitatio

Description

technical field [0001] The invention belongs to the field of axial flux motors, and mainly relates to a composite excitation amorphous alloy axial reluctance motor. Background technique [0002] As a new type of soft magnetic material, amorphous alloy strip has excellent magnetic properties, corrosion resistance, wear resistance, high strength, high hardness and high resistivity, and its thickness is only 0.025mm. Compared with the traditional silicon steel sheet, the amorphous alloy has very small core loss especially in the high frequency range, so the amorphous alloy strip is very suitable for high-speed high-frequency motors. The traditional amorphous alloy axial flux permanent magnet synchronous motor adopts the permanent magnet structure of double rotor and single stator. The surface of the motor rotor with this structure is covered with permanent magnets, and the stator is covered with armature windings on both sides, which has high power density. , high torque densi...
