摘要

随着永磁牵引系统的发展，对电机提出了高功率密度、高转矩密度的要求，热分析在电机设计过程中变得越来越重要。文章以某地铁车辆用永磁直驱同步牵引电动机为例，基于热分析的设计方法提出了设计过程中主要考虑的项点、冷却方式的选择、水冷机座设计的关键参数，并对比了三维仿真结果及试验数据。对比结果表明，定子温度的仿真值与试验数据一致性较好，提出的设计方法可以为永磁直驱同步牵引电动机设计提供参考。

Abstract

With the development of permanent magnet traction system, the requirements of high power density and high torque density are put forward for the motor. Thermal analysis becomes more and more important in the design process of the motor. Taking a permanent magnet direct drive synchronous traction motor for a metro vehicle as an example, based on the design method of thermal analysis, the main considerations in the design process, the choice of cooling mode, and the key parameters of the design of water-cooled frame were put forward, and the three-dimensional simulation results and test data were compared. The comparison results showed that the simulation value of stator temperature was in good agreement with the test data. The proposed design method could provide reference for the design engineer of permanent magnet direct drive synchronous traction motor.
