摘要:
 为了削弱横向边端效应,增大电磁推力,提出格栅型次级作为直线电机新型的拓扑结构。依据电磁场理论,采用有限元分析方法,建立了两类格栅型次级直线感应电机的有限元模型,在瞬态场下,分析了格栅型次级直线感应电机在不同初次级的槽配合时,两类格栅型次级直线感应电机推力、法向力的变化以及波动,对比分析了格栅型次级板与平板型次级的涡流分布以及横向气隙磁场的分布。考虑法向力的影响,计算了在合适槽配合下格栅型次级直线电机的净推力特性,同时得出了两类次级结构产生电磁推力和法向力随速度的变化曲线。通过以上的有限元分析,为直线感应电机优化设计提供了理论参考。
Abstract:
In order to weaken the transverse end effect and increase the electromagnetic thrust,the ladder-type secondary was proposed as a new topology of linear motors. Based on the theory of electromagnetic field,the finite element analysis method was used to establish the finite element model of linear induction motor with two types of ladder-type secondary. In the transient field,the variation of the thrust and normal force amplitude and the fluctuation of force of linear induction motors with the two types of ladder-type secondary under different slot combinations were analyzed,besides,the eddy current distribution and the transverse air gap magnetic field distribution in ladder-type secondary and flat secondary were analyzed and compared. Considering the influence of the normal force,the net thrust characteristics of linear motor with the ladder-type secondaries were calculated under suitable slot combination, in the meantime the variation curves of the electromagnetic thrust and the normal force of two types of laddertype secondary with the velocity were obtained. Through the above finite element analysis,it provides a theoretical reference for the optimization design of linear induction motor.
