摘 要:為研究直線感應(yīng)電機(jī)特性受次級(jí)的影響程度,采用瞬態(tài)有限元方法對(duì)四種不同次級(jí)材料和結(jié)構(gòu)的直線感應(yīng)電機(jī)進(jìn)行了分析,并對(duì)四種直線電機(jī)的堵動(dòng)特性及機(jī)械特性進(jìn)行了對(duì)比。分析結(jié)果表明,鋼銅平板復(fù)合結(jié)構(gòu)的直線感應(yīng)電機(jī)在相同電負(fù)荷時(shí),具有較大的電磁推力輸出和較小的法向力,是應(yīng)用于直線軌道交通的最佳選擇。

Abstract: 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 transportation.
Key words: linear induction motor; secondary; finite element; characteristic analysis
