Optimization Design of Auxiliary Grooves on Rotor of Permanent Magnet Synchronous Motor for Electric Vehicles

Abstract:

In order to reduce the influence of the harmonics of the air-gap magnetic field on PMSM performance, in this paper, the method which is to add auxiliary grooves in the rotor surface is proposed to optimize the air-gap magnetic field of PMSM and reduce the iron loss, torque ripple and noise-vibration caused by the harmonics. During the process, the orthogonal experimental method and the time-stepping FEM were used to optimize the structure of the grooves. Analyzed and compared the test-data and the calculated data,it shows that this method can largely improve motors performance.
