摘要：永磁力矩电机电磁负荷越来越高，随之而来是较高的电机温升。本文针对电机温升问题，设计了三种冷却结构，基于流体力学和传热学基本理论，采用Ansys对冷却结构进行了流场和冷却效率分析。在此基础上建立电机稳态温度场模型，进行了温度场求解，研究了冷却结构流量对电机温升的影响。最后建立了实验平台，验证了分析的准确性。

Abstract: Permanent magnet torque motor(PMTM) electromagnetic load is designed higher and higher, coming with high temperature rise. Aiming at the problem of temperature rise in PMTM, three watercooling structures was researched. Based on the theory of hydromechanics and heat transfer, the fluid and cooling efficiency were analyzed by using the Ansys. Besides, the steady thermal field of the motor was established and the result was solved. The thermal sensitivity to the flow of cooling structure was analyzed. Finally, an experimental platform was established, and the test results verified the effectiveness of analysis.
