摘　　要：基于电磁发射特殊需求,设计了一种新型四定子双边直线感应电动机,提出了此新型四定子双边直线感应电动机的电磁模型,分析了电机上、下定子在动子上所感应涡流的耦合特性和上、下定子端部相邻绕组的耦合特性,建立了这种新型直线感应电动机的耦合等效电路模型。基于等效电路模型,分析了上、下定子以及动子上、下等效绕组相关物理量的耦合性质与电机工况间的关系,研究了动子上、下等效绕组相关物理量在数学上实现解耦的工况条件。实验结果验证了所做研究分析的正确性。A novel double-sided linear induction motor with four stators for the applications of electromagnetic aircraft launch is designed in this paper.The electromagnetic model for this novel motor is proposed,and the coupling characteristics of inductive eddy current of upper and lower stators on shuttles and adjacent end windings of upper and lower stators are analyzed in detail.Based on that,an advanced coupling equivalent circuit model is built for the novel linear induction motor.And based on the advanced coupling equivalent circuit model,the coupling characteristics of relevant physical quantities of the upper and lower stator and upper and lower equivalent windings of shuttle are analyzed.Furthermore,the relationships between the coupling characteristics and motor operation conditions are analyzed,and the operation conditions for mathematical decoupling of relevant physical quantities of shuttle upper and lower equivalent windings are studied.Finally,the experimental results and theoretical derivation results verify the validity and superiority of the proposed design and analysis methods.
