摘要

本文对考虑偏心的永磁同步电机进行了电磁分析和实验研究。永磁同步电机在制造或运行过程中存在的缺陷会导致转子偏心，影响电机的电磁性能。虽然可以使用有限元分析（FEA）来识别转子偏心，但分析是耗时的，并且理解偏心与设计变量之间的直接物理关系是具有挑战性的。因此，采用基于电磁控制方程的解析方法分析偏心对设计变量的影响。将分析结果与有限元分析和实验结果进行了比较，验证了子域方法的有效性。

Analytical and Experimental Approaches to Predicting Magnetic Field Asymmetry and Electromagnetic Forces in Slotted Surface-Mounted Permanent Magnet Machines With Rotor Eccentricity

This article presents an electromagnetic analysis and experimental study of permanent magnet synchronous machines (PMSMs) considering eccentricity. Rotor eccentricity caused by defects in the manufacturing or operational processes of PMSMs affects electromagnetic performances. Although rotor eccentricity can be identified using finite element analysis (FEA), the analysis is time-consuming, and understanding the direct physical relationship between eccentricity and design variables is challenging. Therefore, an analytical approach based on the electromagnetic governing equations was employed to analyze the impact of eccentricity on the design variables. The analysis results are compared with FEA and experimental results to verify the validity of the subdomain method.
