| 摘 要： | 建立电机三维热流场模型,基于流固耦合法,计算大容量高速永磁电机温度场。通过样机温升试验,验证了仿真模型正确性。在此基础上选取导热系数这一影响温度场重要因素作为研究对象,通过控制其在合理范围变化,分析电机温度场对各部件导热系数的敏感性程度。结果为以后高速永磁电机温度场仿真中导热系数的确定提供了参考。

| Abstract: | The 3D temperature model of the machine was established,and fluid-solid coupling method was empoyed to analyze the field. The experimental results have validated the temperature predictions. Based on the proposed thermal field model, some work is given to the analysis of thermal sensitivity to the thermal conductivity, which could help optimum design of high speed permanent magnet machine in future applications. |
