摘 要: 针对高压自起动永磁同步电动机起动过程中长时间低速爬行及大起动电流等问题,将Taguchi算法和有限元相结合,对高压自起动永磁同步电动机的起动性能进行综合优化。基于磁路法得到电机的基本设计参数和转子槽参数的水平值;利用Taguchi方法建立正交表,得到因子组合;利用有限元法对各组合进行分析,得到不同组合下的起动性能参数;利用极差和方差方法,就转子槽参数对起动性能的影响规律和所占比重进行分析,从而得到高压自起动永磁同步电动机起动性能优化最优组合方案,并进行了样机起动性能测试实验。研究结果表明:将Taguchi正交方法应用于高压自起动永磁同步电动机设计优化上,在保证全面分析的基础上减少分析次数,实现了多目标的同时优化,提高了起动性能,可以为高压自起动永磁同步电动机的设计提供指导方向。 Aiming at the problems of long time low speed creep and large starting current in the starting process of high voltage line-start permanent magnet synchronous motor( HV-LS-PMSM),the starting performance of HV-LS-PMSM was optimized by using the Taguchi method and the finite element method. The basic design parameters and the value levels of the rotor slot were obtained based on magnetic circuit method. Then the orthogonal table was established by Taguchi method,and the combination of factors was obtained. The finite element method was used to analyze different combinations,through that the starting performance parameters were obtained. Using the method of extreme difference analysis and variance analysis,the influence law and the proportion of the rotor slot parameters on the starting performance were analyzed,so as to get the optimal combination scheme of HV-LS-PMSM starting performance. And the starting process was tested on the platform. The results indicate that the Taguchi orthogonal method applies to HV-LS-PMSM design and optimization,which can reduce the times of analysis on the basis of the comprehensive analysis,and achieve the multi-objective optimization,and improve the starting performance.And the conclusions provide guidance for the design of HV-LS-PMSM.
