Abstract

The invention discloses a novel dual-stator Halbach alternating pole permanent magnet vernier motor, comprising a first stator structure, a second stator structure and a rotor structure, wherein the rotor structure is arranged on the first stator structure and the second stator structure In the middle; the first stator structure and the second stator structure are stator structures with the same structure, and both include a stator core, and the stator core is provided with stator slots and stator teeth at uniform intervals in the circumferential direction, and the stator slots are embedded in the There is an armature winding, the tooth end of the stator is split into two modulation poles, and a Halbach permanent magnet array is arranged between the modulation poles; the rotor structure includes a rotor iron core, and the rotor iron core is provided with rotor slots at equal intervals in the circumferential direction , rotor permanent magnets are embedded between the rotor slots. The invention improves the air-gap magnetic density of the motor, effectively reduces magnetic flux leakage, and simultaneously achieves the purpose of reducing the amount of permanent magnets and enhancing the mechanical structure strength of the rotor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a novel double-stator Halbach alternating pole permanent magnet vernier motor. Background technique [0002] The vernier permanent magnet motor (Vernier PM Machine) is a new type of motor based on the theory of magnetic field modulation that has been gradually developed in recent years. The topology of this motor has the advantages of ultra-high power density and simple mechanical structure. It has good applications in fields such as electric vehicles and electric vehicles. [0003] At present, related technologies of permanent magnet vernier motors have appeared. The application number is 201310069627.8, and the name of the invention is "radial magnetic field double stator vernier motor". A radial magnetic field double stator vernier motor is proposed. The relative positional relationship between the stator teeth and the rotor pole shoes is set by the arrangement of the rotor an...
