摘要
当牵引电机运行时,电机内部的电磁场分布及变化情况直接影响牵引电机的运行状态与性能。介绍异步牵引电机的工作原理及等效电路,基于Ansoft Maxwell 2D仿真软件对CRH2的牵引电机MT205进行电磁仿真,得到MT205的电磁场分布及电机特性曲线,为牵引电机性能优化提供理论依据。
When the traction motor works,the distribution and changes of the electromagnetic field within the motor directly affect its running status and performance.This paper introduces the working principle of the asynchronous motor and its equivalent circuit,then simulates the electromagnetic field of the motor MT205 by Ansoft Maxwell 2D,getting the electromagnetic field distribution and some motor characteristic curves,which provides a theoretical basis to optimize the traction motor.
