摘　　要：根据表贴式永磁同步电动机和内置式永磁同步电动机的结构特征,以电机学、等效磁路模型、双反应原理以及有限元方法为理论基础,提出了电机直轴和交轴的电枢反应电抗的计算方法。并结合实例,采用有限元法和磁路解析的方法,对不同转子结构电机的电枢反应电抗进行了计算,并将两种计算方法得到的结果进行了比较,验证了该方法的正确性。According to the construction features of surface mounted permanent magnet motors （SPMSM） and interior permanent magnet motors（IPMSM） ,two calculation methods for armature reaction reactance were proposed on the basis of electric machine theory, double-reaction principle, equivalent magnetic circuit models, and finite element method. Take 1 kW SPMSM and 11 kW IPMSM as examples, the armature reaction reactance was calculated using magnetic current analytic method and finite element method, and the calculation result was compared with each other, which proved the validity of the two methods.
