【摘要】：以一台50 k W永磁驱动电机为例,根据流体力学和传热学原理,利用有限体积法对电机温度场进行了研究,分析出其温度分布规律。该结果与实验所获数据相吻合,证实了计算方法和计算结果的合理性。但是为了有效地解决由于接线盒所在区域温升过高,温度梯度较大的问题,提出4种对接线盒结构的优化方案,对其不同方案下电机整体温度分布及接线盒所对应的电机内部径向区域温度场特性进行了详细地分析,所得结论为永磁驱动电机结构的优化设计提供了理论参考。
[Abstract]:Taking a 50kW permanent magnet driven motor as an example, according to the principles of fluid mechanics and heat transfer, the temperature field of the motor is studied by using the finite volume method, and the temperature distribution law is analyzed. The results are in agreement with the experimental data and verify the reasonableness of the calculation method and the calculated results. However, in order to effectively solve the problem of high temperature rise and large temperature gradient in the junction box area, four optimization schemes for the junction box structure are proposed. The whole temperature distribution of the motor and the temperature field characteristics of the radial region of the motor corresponding to the junction box under different schemes are analyzed in detail. The results provide a theoretical reference for the optimization design of the structure of the permanent magnet drive motor.
