Abstract

The invention discloses a synchronous reluctance motor rotor, which comprises an iron core. A circular hole is formed in the middle of the iron core; n parts are uniformly arranged on the iron core, and n is the same as the number of poles of the motor; each part is sequentially provided with a first layer of air magnetic barrier, a second layer of air magnetic barrier and a third layer of air magnetic barrier with radians from inside to outside; magnetic bridges are arranged in the middle positions of the first layer of air magnetic barrier and the second layer of air magnetic barrier; and agroove is formed in the outermost part of each part. According to the invention, the problems of serious motor leakage inductance, low mechanical strength, quite small salient poles, insufficient electromagnetic torque and the like are solved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a synchronous reluctance motor rotor. Background technique [0002] With the development of power electronics technology and the improvement of the performance of permanent magnet materials, permanent magnet synchronous motors have been widely used in occasions that require high control performance. However, permanent magnet synchronous motors have too strict temperature restrictions and poor overload capacity. Difficulty in field weakening control and other disadvantages. At the same time, the consumption of rare earth resources has been too fast in recent years, and it is very likely to face shortages in the future, which will hinder the development of permanent magnet synchronous motors. However, there is no permanent magnet on the rotor of synchronous reluctance motors, and the processing is simple and the cost is lower. , no difficulty in field weakening, high temperature los...
