Each reluctance rotor comprises a reluctance rotor iron core and a plurality of magneticbarrier structures which are uniformly arranged along the circumferential direction of the reluctance rotor iron core. Each permanent magnet rotor comprises a permanent magnet rotor iron core and a plurality of permanent magnets uniformly arranged on the permanent magnet rotor iron core. By utilizing the axial composite permanent magnet auxiliary synchronous reluctance motor rotor, the problems ofinsufficient permanent magnet torque utilization, low mechanical strength and high processing cost of a radial composite permanent magnet auxiliary synchronous reluctance motor can be effectively solved, the reliability of a permanent magnet auxiliary synchronous reluctance motor is improved, and the application occasions of the permanent magnet auxiliary synchronous reluctance motor are also widened.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to an axial composite permanent magnet assisted synchronous reluctance motor rotor. Background technique [0002] Motors are an important part of industrial systems, and motors with excellent performance are crucial to industrial systems. The synchronous reluctance motor increases the convex probability of the motor by setting multi-layer magnetic barriers on the rotor, thereby generating reluctance torque, which has the advantages of low cost and high power density. However, the synchronous reluctance motor has the problem of low power factor, which will greatly increase the capacity requirements of the motor system for the drive frequency converter, dilute the cost advantage, and greatly limit the application of this type of motor. [0003] The traditional radial compound permanent magnet assisted synchronous reluctance motor follows the structural characteristics of t...
