摘　　要：为准确计算定子温升,对计算区域进行了合理的网格剖分,建立了异步电机定子的热网络数学模型,采用高斯-赛德尔迭代法对模型进行了求解。实验结果表明,采用热网络法计算电机定子温升具有较高的准确性。基于热网络法的高功率密度异步电动机定子温升计算实用、可靠。In order to calculate asynchronous motor＇s stator temperature accurately, a mesh on the calculation area in the stator was made at first, builded the area＇s thermal network mathematics model secondly, used the Gauss -Seidel iterative method to calculate the mathematics model finally. The experiment showed that used the thermal network to calculate the motor temperature might get the result accurately. The method has been applied and credible.
