Description

technical field [0001] The invention relates to a permanent magnet motor with high power density and high torque density, belonging to the field of motors. Background technique [0002] Compared with electric excitation motors, permanent magnet motors, especially rare earth permanent magnet motors, have significant advantages such as simple structure, reliable operation, small size, light weight, low loss, and high efficiency; The scope is extremely wide, covering almost every field of aerospace, national defense, industrial and agricultural production and daily life. According to the permanent magnet magnetic circuit structure, the permanent magnet motor rotor structure is divided into surface mount type and magnetic accumulation type. The rotor adopts a magnetic-concentration structure. Compared with the surface-mounted rotor structure, the effective harmonic flux density in the air gap can be greatly improved, which can increase the power density of the motor and improve...
