摘　　要：随着我国高速铁路的快速发展,对异步牵引电机的运行性能提出了越来越高的要求,为进一步优化异步牵引电机的性能,就需要准确计算异步牵引电机内电磁场的分布和特性。应用场路耦合法,在忽略定转子端部对电磁场分布影响的前提下,建立了异步牵引电机电磁场分析的场路耦合模型。基于所建模型,利用Ansys软件对一台三相4极异步牵引电机进行二维电磁场仿真计算,得到电机在不同运行状态的磁力线分布和定子电流。仿真结果与电机的设计数据有很好的一致性,证明所建场路耦合模型的正确性,为异步牵引电机的优化设计提供了理论性指导。Without considering the influence of the end part of stator and rotor on the distribution of electromagnetic field,a coupled field-circuit model is set up for the analysis of asynchronous traction motor by coupled field-circuit method.Based on the model,a simulation calculation of two-dimensional electromagnetic field is carried out on a three-phase 4-pole asynchronous traction motor by Ansys software and the magnetic line distribution and stator current of motor at different running state are achieved also.The simulation result can prove that the coupled field-circuit model is correct by comparing with design data and can provide theoretical guide for the optimization design of the asynchronous traction motor.
