Abstract：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.
