摘要
采用流体相似理论和三维有限元法计算了计及定子绕组股线绝缘和不计股线绝缘两种情况下 ,具有轴径向通风系统的大中型异步电动机定子三维温度场 ,分析了股线绝缘对定子温度场的影响。采用有限元法对若干影响定子温度场的相关因素进行了数字模拟研究 ,得出了相应的结论。
In this paper, Theory of Fluid Similarity and 3D FEM is used to calculate the 3D stator temperature field of large and medium scale asynchronous motor, which have radical and axial ventilating system, and both case of considering interturn insulation or not are calculated. The influence of interturn insulation on stator temperature field is analysised. The related factors affecting the stator temperature field is study in use of FEM and some useful results are achieved.
