摘　　要：提出一种新型钢次级弧形直线感应电动机,采用多层行波电磁场理论建立该电机的区域模型,推导出法向力计算公式,建立该钢次级弧形直线感应电动机三维瞬态有限元仿真模型,仿真结果与解析计算结果相吻合。并与同参数的扁平形钢次级直线感应电动机作比较,结果表明这种钢次级弧形直线感应电动机在不改变推力的前提下能够减少法向吸力,提高推力与吸力比值,为该类电机的性能计算、优化设计奠定理论基础。A new steel secondary arc linear induction motor was proposed in the paper. The regional model for the motor was buih, and the calculating formula of normal force was deduced with the electromagnetic theory of multi-layer traveling waves. The 3-D transient FEM model of the steel secondary arc linear induction motor was established. The analytic calculating matches to the simulation result by coincidence. By comparing with the same parameter of the flat steel secondary linear induction motor, the results prove that this steel secondary arc linear induction motor is able to reduce the normal force at the premise of not changing thrust force, to increase the rate between the thrust and the attractive force, and to lay the theoretical foundation for the calculating performance and the optimizing design of this proposed motors.
