A Thermal Analysis for the Canned Motor Stator Winding Maximum Temperature

本文使用MATLAB软件工具,对屏蔽泵电机定子求解正常运行工况的最大线圈温度。首先使用基本公式保守得到定转子间冷却水温度的解析解,建立定子线圈轴向热传导模型和不同轴向位置定子线圈温度到水域的径向热传导模型,使用有限差分法,得到屏蔽泵电机的最大定子线圈温度。得到最大线圈温度后,并在此模型的基础上对最大线圈温度影响因素进行了分析,得到对最大线圈温度和屏蔽套温度影响较大的因素。使用MATLAB软件分析,计算时间短,在保证计算精度的基础上,不失为一种高效率的分析方法。

In this document,there is the thermal analysis for the canned motor stator winding maximum temperature in nominal operating condition using the software MATLAB.First,the conservative analytical temperature value of annulus between the stator can and rotor can is obtained from the basic equation.Next,an axial thermal conduction model and many radial thermal conduction models for different axial locations are built,then the finite method is used for solving to get the sta-tor winding maximum temperature.After finishing the solution,the influence factors of maximum winding temperature are analyzed based on the model,and the influence factors on maximum winding temperature are obtained.After all,the analysis with using MATLAB software,of which calculation time is short,in order to ensure the accuracy of the basis,is a high-efficiency analysis.
