摘要
针对一种新型外转子结构的双凸极永磁电动机,在二维磁场下,采用自编VC++有限元程序对其空载和负载时的磁场以及电枢电流对电动机磁场的影响等进行了研究,得出了空载和负载时电动机的场图,以及空载时转子在不同位置时的气隙磁密曲线,同时也得出了永磁磁链和反电势随转子位置角的变化曲线。这些静态特性的获得为以后分析该电动机的动态特性奠定了理论基础。
Studied on a novel external rotor doubly salient permanent magnet machine in this paper.On the two dimensional magnetic field,it took finite element program based on VC++ analysis for the distributing of magnetic field on no-load motor and full-load motor,and it analyzed and explained influences of armature current on magnetic.It got the magnetic field pictures for the motor no-load motor and full-load motor,and it got the magnetic flux density in the air gap distribution curve in different rotor angle on n...
