摘要
以氦冷异步电机定转子全域为研究对象,运用数值方法计算各位置热源密度,建立了该电机通风结构3D计算模型,基于流体力学和工程热力学原理,采用流固耦合方法对电机温度场进行计算分析。得到了氦冷电机在氦气环境下运行的温度场分布。结果表明:氦气冷却性能较好,电机上下端部处为其主要发热源,计算结果为冷却设计优化提供理论依据。
The stator-rotor of helium-cooled induction motor as the research object.It established the 3 D physical model of the motor,and then calculate the heat source density by using nunerical method.numerical calculation of the motor＇s temperature field was carried out with the fluid solid coupling method based on the fluid mechanics and thermodynamics principle.Stator-rotor coupled thermal field numerical calculation of the helium-cooled induction motorwas obtained.The results show that helium has certain advantages in termsof cooling and thefront and rear ends of motor ismain heating area.The conclusion provide a theoretical basis for the optimization of the cooling design.
