采用不同次级结构的单边直线感应电机性能分析

摘要

In order to study impact degree of secondary structure on the linear induction motor, this paper adopted the finite element method to carry out analysis to four kinds of different secondary materials and structures and compared the locked-mover characteristics and mechanical characteristics of four kinds of linear motors. Analysis result shows that the steel-copper plate composite structure is with higher thrust force and smaller normal force under the same electrical load of linear induction motor, which is the best selection of application in linear railway transpor-tation.%为研究直线感应电机特性受次级的影响程度，采用瞬态有限元方法对四种不同次级材料和结构的直线感应电机进行了分析，并对四种直线电机的堵动特性及机械特性进行了对比。分析结果表明，钢铜平板复合结构的直线感应电机在相同电负荷时，具有较大的电磁推力输出和较小的法向力，是应用于直线轨道交通的最佳选择。
