Usually, in order to improve the torque density and efficiency of the motor, it is mainly to start with the optimization of the motor magnetic steel structure, the optimal design of the motor, the manufacturing process and equipment, the magnetic circuit structure, high-ranking electrical steel, and high-performance permanent magnet materials. However, due to the disc type Due to the limitation of the electromagnetic conversion principle of the motor and the performance of the material itself, it is impossible to achieve higher torque density and efficiency, and there is a certain gap with the performance of foreign disc motors.
