外转子双凸极永磁电动机有限元分析

提出了一种外转子双凸极永磁电动机的设计方案;为了保证分析计算的准确性,通过有限元方法使得诸如永磁体导致绕组磁通回路发生变化、永磁体和绕组的电磁反应以及绕组之间存在互感等用传统路的方法难以解决的问题得到解决。分析了该电机的磁场分布和气隙磁密,为进一步研究提供了依据。

An External Rotor Doubly Salient Permanent Magnet Motor's Final Element Analysis

In the paper,an external rotor doubly salient permanent magnet motor(ERDSPM)is designed.It is analyzed and calculated through final element analysis(FEA).So the problem suchas the exist of permanent magnet,the winding's flux loop are greatly changed,the permanent magnet is response with the windings and analysis of motor is very difficulty for mutual inductance of the winding with each other are solved.And the profiles of distribution of B and H about the air gap around the circle are plotted.And provide theoretic basis for research deeply of doubly salient permanent magnet machine.
