Abstract

The invention discloses a double-rotor and double-stator axial switch reluctance motor for an electric sliding system which comprises a shell, an end cover, a stator, rotors and a motor shaft. The stator consists of a stator core, a stator support frame and stator windings. The stator core consists of 12 iron cores, and the 12 iron cores are uniformly distributed in the radial circumferential direction. The stator support frame is annular and is fixedly arranged in the shell. Through holes matching the positions and the section shapes of the 12 iron cores are formed in the stator support frame, and the iron cores penetrate through the through holes and are fixed with the stator support frame. The two sets of stator windings are respectively wound on the two sides of the iron core. The tworotors are arranged on the two sides of the stator respectively, and each rotor is integrally formed by one disc-shaped back iron and eight salient pole structures. The eight salient pole structures are uniformly distributed on one side, close to the stator, of the back iron along the circumferential direction. The middle of the motor shaft is fixedly connected with the stator support frame, and the two ends of the motor shaft are connected with the two rotors through bearings. The motor is small in axial size and simple and reliable in structure.

Description

technical field [0001] The invention relates to a motor, in particular to a double-rotor and double-stator axial switched reluctance motor for an electric sliding system. Background technique [0002] In-wheel motor technology is one of the cutting-edge technologies of new energy vehicles, and switched reluctance motor is a motor with simple structure, high reliability and wide adjustment range. The combination of the two in-wheel motors is applied to the ground taxiing drive of aircraft. Cutting-edge technology in the industry. [0003] The axial flux motor is characterized by small axial size and high power density, which is more suitable for the application of hub motors. Most of the traditional axial switched reluctance motors have a single disc structure, and its main principle is still not much different from that of radial switched reluctance motors. They are all double salient pole structures, and operate according to the principle of minimum reluctance. Magnetic p...
