| 摘 要： | 针对谐波电流引起的转子涡流损耗在某些表贴式永磁同步电机中可能会引起很高的温升的问题,研究了一种永磁同步电机转子涡流损耗的解析计算方法,该方法考虑了转子电枢反应和电机有限长的影响.在二维直角坐标系下,建立电磁场方程,通过对电磁场方程的解析求解得到转子涡流损耗的解析表达式.通过一个端部系数来等效电机有限长的影响.针对转子涡流损耗测量困难的问题,采用了一种能准确分离出转子涡流损耗的间接测量方法.实验结果表明所提出的解析计算方法可行.

| Abstract: | Rotor eddy current losses induced by the harmonic currents may be significant in some kinds of permanent magnet synchronous machines(PMSM),which may cause overheat and lead to failure.This paper presents an analytical method for calculating the eddy current losses,taking the influence of the rotor eddy current reaction and the finite axial length of the rotor into consideration.The analytical expression for the rotor eddy current losses was derived from the electromagnetic equation in rectangular coordinate... |
