电动汽车用永磁同步电机电磁振动与噪声性能优化
Optimization of Vibration and Noise Performance of Permanent Magnet Synchronous Motor for Electric Vehicles
摘要
Abstract
In the design of the motor used for electric vehicles(EVS),vibration and noise problems are often ignored, which reduce the reliability and service life of the motor. In this paper,an interior permanent magnet synchronous motor(IPMSM)with high power density is taken as an example,and its electromagnetic vibration and noise problem is investigated and optimized. Firstly,the factors that generate the electromagnetic force harmonic of IPMSM are analyzed by theoretical derivation. Furthermore,the mode and electromagnetic harmonic distribution of the motor are calculated and analyzed by establishing the electromagnetic?structure?sound coupling simulation model. Then,by combining finite element method(FEM)with modern optimization algorithm,an electromagnetic vibration and noise performance optimization method is proposed in the electromagnetic design stage of the motor. Finally,an IPMSM is optimized by this method for electromagnetic vibration and noise performance. The results of comparison between before and after optimization prove the feasibility of the method.关键词
