| 摘 要： | 电机温升是影响电机性能和运行可靠性的主要元素之一,温度校核已成为电机设计过程中的重要环节。目前大多采用电机三维温度场仿真方法,但是因电机端部绕组结构复杂,热流场耦合性强,对计算结果准确性影响较大。建立3种定子绕组端部建模简化方式,使用Fluent仿真软件平台对某感应电动机热流场进行了仿真计算及分析。结果表明,建模时可以将定子端部绕组简化为拉直向上弯折的二维结构,这种简化方式兼具建模时间短、仿真精度高等优点。所得结论对快速进行电机热流场仿真、缩短电机设计周期有一定的参考作用。

| Abstract: | The temperature rise of the motor was one of the main factors that affected the performance and reliability of the motor. At present, the three dimensional temperature field simulation method was adopted, but because of the complex structure of winding and the strong coupling of heat flux field,which affecting the accuracy of the calculation results largerly. The simplified modeling method of 3 kinds of stator end winding was established, and the simulation and analysis of the heat flux field of the induction motor was carried out by using the Fluent simulation software platform. The results showed that the model could be simplified as a twodimensional stator end winding structure of straightening bent upward, the simplified method had both advantages of short modeling time and high simulation precision. The conclusions could be used as a reference for the simulation of the heat flux field and shorting the design period of the motor. |
