摘要:针对永磁同步电机的电抗参数的变化规律进行研究。介绍并完善等效交直轴磁路法,对不同功率,不同磁路结构的永磁同步电机进行电抗参数的计算,根据计算结果总结电机电抗参数随内功率因数角的变化规律,以及与磁路结构的关系。对多台电机进行电抗参数的测试,在测试过程中对电压积分法进行完善,使得测试方法更为准确,并将测得数据与计算数据进行对比。 关键词:永磁同步电机;交轴电枢反应电抗;直轴电枢反应电抗;有限元分析 Abstract: The paper study the changing rule of the reactance parameters of PMSM. The equivalent d axis and q axis magnetic circuit method will be introduce and use this method calculate reactance parameters of different power and different structure′s PMMS, conclude the changing rule of the reactance parameters of PMSM with ψ and magnetic circuit structure. The reactance parameters of PMSM will be tested. In process the voltage integral method will be improved, making the method more accurate. The result will be compared with the calculate data. Key words: PMSM;q axis armature reaction reactance;d axis armature reaction reactance,;finite element analysis
