摘　　要：单边直线感应电机通常采用复合次级来提供较大的牵引力和较小的法向力。通过对单边直线感应电机牵引力计算公式的分析,找到复合次级与牵引力的关系,提出一种能提高电机效率的多阶段变化次级铝板厚度方案。该方案通过改变次级铝板厚度来实现各种运行速度下的最大牵引力。采用有限元仿真出次级轭铁、次级铝板对牵引力的影响,仿真出多阶段变化次级铝板厚度方案提供的最大牵引力,并与固定复合次级方案进行比较,验证多阶段变化次级铝板厚度方案的优越性。Single-side linear induction motor provide large traction force and the smaller normal force by compositesecondary. Through the analysis of the calculation formula of the traction force of the single-side linear induction motor, therelationship between the composite secondary and the traction force was found. A new method for improving the efficiency ofmulti - phase change of secondary aluminum plate can change the thickness of the secondary aluminum plate to achieve themaximum traction force of various operating speeds. Using finite element the effect of the secondary iron yoke, secondary aluminumon the traction force was simulated, and the maximum traction force provided by multi stage changes of secondaryaluminum thickness was also simulated. The advantages of the multi stage changes of secondary aluminum thickness wereverified by comparing with the fixed composite secondary.
