Abstract

An embodiment of the present invention relates to the motor technology field, and discloses a switched reluctance motor, an electric vehicle and a switched reluctance motor system having an inner rotor and outer stator structure. The switched reluctance motor comprises a housing, an inner rotor and an outer stator. The inner rotor and the outer rotor are arranged inside the housing. The outer stator comprises a plurality of circumferentially spaced stator teeth and stator slots among the stator teeth. The ratio of the slot width of the outer stator to stator teeth width ranges from 1 to 1.25. The switched reluctance motor, with large torque and low speed performance, has a wide efficiency platform and can achieve high power density. While producing low noise, it has good environmental adaptability. In addition, it provides reliable performances and has a long service lifetime. Requiring simple technology in its making, it costs not so much as well. All enable the motor to be widely used in electric vehicles.

Description

technical field [0001] The invention relates to the technical field of electric motors, and relates to an electric vehicle, a switched reluctance motor, and a switched reluctance motor system. Background technique [0002] The inventors have found in practice that the wheel hub drive motors of high-power electric vehicles generally use permanent magnet synchronous motors and axial magnetic field motors, and generally seldom use switched reluctance motors. [0003] The performance of these three motors is analyzed below: [0004] 1. The structure of the axial magnetic field motor is complicated, the production cost is high, and the practical application value is not high. [0005] 2. The switched reluctance motor in the prior art is generally made as an inner rotor motor, and an outer rotor hub motor has not been adopted. The low-speed stability, noise, and power density of the switched reluctance motor used as an inner rotor are still inferior to those of the permanent mag...
