Abstract

The present invention relates to a permanent magnet synchronous motor with hybrid magnetic circuit arrangement. The permanent magnet synchronous motor with the hybrid magnetic circuit arrangement comprises a stator iron core (1) and magnetic steels, the magnetic steels are arranged at the circumferential edge of a rotor iron core (2) unevenly, and comprise the tangential magnetic steels (7), the linear magnetic steels (5) and the V-shaped magnetic steels (6). Each V-shaped magnetic steel (6) is formed by arranging two magnetic steels, and the linear magnetic steels (5) are located at the inner side of a V-shaped magnetic steel set (6) and are close to the circumferential edge of the rotor iron core (2). The tangential magnetic steels (7) are arranged on a q-axis of the motor, and the number of the tangential magnetic steels (7) and the linear magnetic steels (5) is equal to the number of the V-shaped magnetic steels (6) and is equal to the series of the motor. The inner side of the rotor iron core (2) is equipped with the de-weight holes having the same number with the series of the motor, and the de-weight holes comprise the large de-weight holes (3) and the small de-weight holes (4). The permanent magnet synchronous motor with the hybrid magnetic circuit arrangement of the present invention solves the problems of the motor of high power density and cost, wide speed regulation range and electromagnetic noise.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a permanent magnet synchronous motor with mixed magnetic circuits. Background technique [0002] In recent years, with the rise of the new energy vehicle industry, the vehicle drive motor has higher and higher requirements on the peak torque and speed range of the motor. In order to meet the size of the vehicle and reduce the system cost, the system hopes that the motor has a larger reluctance torque share. . According to the survey: At present, the proportion of the salient pole reluctance torque of the motor developed by major motor companies at home and abroad and the torque generated by the permanent magnet steel are generally less than 45%. If the ratio can be further increased, the system cost can be effectively reduced and the motor power can be improved. Performance and system matching. In the hybrid vehicle system, the space is tight, and the requirements for the power ...
