用派克方程分析开关磁阻电动机

根据开关磁阻电动机气隙磁导的变化情况，把ＳＲＭ的一相绕组通电后的电磁关系，等效成一台假想的极对数Ｚ２／２，但运行于某种不对称的工作条件的三相凸极同步电动机的电磁关系，建立了与ＳＲＭ相等效的同步电动机模型，使用派克方程来分析ＳＲＭ的工作机理成为可能，并用坐标变换、Ｚ变换和拉氏变换法来求取ＳＲＭ的定子相绕组电流及电磁转矩。，

Analysis for a Switched Reluctance Motor Using Park''s Equations

The electromagnetic relationships due to a phase winding being excited in a variable - speed switched reluctance motor (SRM) with Z1/Z2 poles have been successfully equivalent to those of an imaginary three phase salient - pole synchronous motor with Z2/2 pole - pairs which is assumed to run in a given unbalanced operating condition according to the variations of the air gap permeance in SRM. The model here provides the back ground with you to analyse the working principle of SRM by utilizing the park's equations,and then to abtain the phase winding current and the electromagnetic torque by using the method of coordinate transformation and Z -transformation combinated with Laplace -transformation. The current and the torque calculated by the method mentioned here for the prototype motor are also given and compared with the test results.
