摘要
损耗引起的温升是确定电机定额的主要因素。利用模拟软件Fluent与流固耦合传热机理,在一台1.9kW永磁同步电机上研究了自然冷却和强制风冷两种冷却方式对电机温度分布特征的影响,并制作样机进一步试验。仿真结果与试验结果相近,验证了仿真的准确性。
The temperature rise caused by the loss is the main factor in determining the motor rating.Using the simulation software Fluent and the fluid-structure coupling heat transfer mechanism,the influence of natural cooling and forced air cooling on the temperature distribution characteristics of the motor was studied on a 1.9kW permanent magnet synchronous motor,and a prototype was made for further testing.The simulation result is similar to the test result,which verifies the accuracy of the simulation.
