Abstract

The invention provides a rotor structure, a permanent magnet assisted synchronous reluctance motor and an electric vehicle. The rotor structure includes a rotor body. The rotor body is provided with an inner permanent magnet slot and an outer permanent magnet slot. The inner permanent magnet slot and the outer permanent magnet slot A magnetic conduction channel is formed between the permanent magnet slots of the layer, the cross section of the inner permanent magnet slot along the radial direction of the rotor body is U-shaped, and the outer permanent magnet slot along the radial direction of the rotor body is V-shaped. structure. Such arrangement can effectively utilize the material of the rotor body, and at the same time optimize the magnetic circuit of the rotor body. The material utilization rate of the rotor is effectively improved, and the efficiency of the motor with the rotor structure is effectively improved at the same time.

Description

Technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a rotor structure, a permanent magnet auxiliary synchronous reluctance motor and an electric vehicle. Background technique [0002] In the prior art, due to the improper arrangement of the permanent magnet slots on the rotor, the effective utilization rate of the rotor material is reduced, resulting in the problems of increased motor rotation and low motor efficiency in the prior art. Summary of the invention [0003] The main purpose of the present invention is to provide a rotor structure, a permanent magnet auxiliary synchronous reluctance motor and an electric vehicle to solve the problem of low motor efficiency in the prior art. [0004] In order to achieve the above objective, according to one aspect of the present invention, a rotor structure is provided, including: a rotor body, the rotor body is provided with an inner layer permanent magnet slot and an outer layer p...
