摘　　要：本文基于有限元法研究了一种新型三相12/10极切换磁通型双凸极永磁电机的电感特性。首先介绍了该电机的结构特点和运行原理;其次比较了静态电感和动态电感的定义;并在此基础上采用通用的定子三相坐标系和dq轴两相坐标系变换将三相绕组电感变为直轴和交轴电感;针对该种方法耗时多、运算量大的缺点,提出了一种基于两个特殊转子位置的简单快捷的方法,可以直接计算得到直轴和交轴电感,所得结果与传统方法计算结果比较验证了该方法的有效性,并得到了样机实测电感数据的验证。In this paper, the inductance characteristics of a novel 3-phase 12/10 pole （12-statortooth/10-rotor-pole） flux-switching permanent magnet （FSPM） machine with doubly-salient structure is investigated based on finite element （FE） analysis. Firstly, the topology and operation principle of the machine are presented. Secondly, the apparent （static） and incremental （dynamic） inductances are defined. Then, the conventional calculation method of transforming the 3-phase inductances in stator frame into dq-axes rotor frame is performed, which consumes lots of time. To avoid it, a newly simplified and fast method is proposed to obtain the d-axis and q-axis inductances directly and accurately at only two special rotor positions. The proposed method is validated by the comparison of the predicted results in two ways. The experimental measurement verifies the predicted results.
