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,需要准确计算电机电磁场的分布和特性。采用场路耦合法,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3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指导。With the rapid development of the high-speed railway, it is more and more important to accurately calculate the distributing of the electromagnetic field, which could help optimize the performance of asynchronous traction motor. Without considering the influence of the end, a finite element model was setup to solve coupled field-circuit motion problems for the analysis of three phase asynchronous traction motor. Using the finite element software Ansys, the asynchronous traction motor was analyzed under different running state, then got the distributing of the electromagnetic field and the current of the stator. By comparing with the design data, the model was proved effective and could give academic instruction for the optimization of the asynchronous traction motor.
