介绍了内嵌式永磁同步电动机（IPMSM）的直(d)轴和正交(q)轴电感特性，重点讨论了交叉耦合效应。根据转子位置在整个定子电流激励下，研究了相感的非线性变化。我们还提出了一种新的分析方法，称为固定渗透率法（FPM）。我们将这种方法（FPM）应用于大功率线性运动应用的钢芯永磁直线同步电动机。实验数据证实了FPM方法得到的结果。利用FPM分析了样机的磁饱和特性，并将气隙磁通密度、d轴和q轴电感与传统有限元分析结果进行了比较。
The direct (d)- and quadrature (q)-axis inductance characteristics of the interior permanent-magnet synchronous motor (IPMSM) are presented, with an emphasis on the cross-coupling effects. Nonlinear variation of phase inductance is investigated, according to the rotor position on entire stator current excitations. We also propose a new analytical method, called the fixed permeability method (FPM). We applied this method (FPM) to steel-cored permanent-magnet linear synchronous motors for large powered linear motional applications. Experimental data were found to corroborate the findings obtained by the FPM method. We also used FPM to analyze magnetic saturation characteristics of the prototype IPMSM, and compared the air-gap flux density and d- and q-axis inductance with the conventional finite element analysis results.
