摘要
建立了双馈直线电机(DFLM)的一维磁场模型,求解了气隙磁通密度表达式。详细分析了气隙磁通密度解析式的构成和各部分对气隙磁场分布的影响,并使用Ansoft Maxwell软件对短初级DFLM进行了建模与仿真。结果表明端部效应在入端随速度的提高而增强,对出端气隙磁场影响很小,可以忽略。由仿真数据可知,相比于直线感应电机,DFLM的纵向端部效应明显减弱。
The one-dimensional field model of a doubly-fed linear motor was established （DFLM）, and the air gap magnetic field expressions was given. The gap nlagnetic flux density composition and its effect of all parts on the air-gap magnetic field distribution were analyzed, and model and do simulation a short primary DFLM running at low speed with Ansoft Maxwell. The results showed that end-effect enhanced at the in-side and too weaken to be ignored at the out-side. According to the simulation, compared to the LIM, DFLM＇s end-effect was significantly reduced.
