摘　　要：为研究船舶驱动用异步电机传热性能及温升特性,以一台Y2-250M-4型、55 k W异步电机为例,采用有限体积元法对其三维稳态温度场求解计算,分析了电机额定负载运行时主要部位的温升特性.同时,根据其船舶驱动的用途特点,实际运行时负载多呈变化,因此对电机不同负载工况的温升进行求解并对比分析.通过搭建实验平台,将实验数据与计算结果相对比验证.结果表明:无论何种工况,电机的最高温升均出现在转子导条处;随着负载的增大,电机各主要部位的最高温升呈增加趋势,并且其增幅逐渐趋于显著.该研究为电机设计及性能优化、故障预测提供一定参考.In order to study the heat transfer performance and temperature rise property of asynchronous motor for ship drive, a Y2-250M-4, 55 kW asynchronous motor was taken as the research object. Using the finite volume element method for the three-dimensional steady temperature field solving and calculation, the temperature rise property of motor main parts were analyzed at rated load. Meanwhile, based on the application and feature of ship drive, load tends to change in actual operation. Therefore, the temperature rise of motor in different load condition was solved and comparativeg analyzed. Through experimental platform, the experimental data and the calculating result were compared to be verified. It shows that whatever the operating conditions, the highest temperature rise of motor till presents in the bar of rotor. The highest temperature rise of motor main parts tend to increase with the raise of load. And its increase amplitu＇de tends to be remarkable gradually. The study can provide some reference for motor design, performance optimization and fault prediction.
