介绍了一种内燃机车牵引电动机绕组温度场的计算方法。这种方法不仅适用于铁路部门用来选择列车驾驶工况 ,而且还适用于机械制造厂用来设计新产品。文内给出了用这种方法对内燃机车用ЭД 1 1 8А型牵引电动机所进行的计算和分析。
A calculation method of winding temperature field of traction motor for diesel locomotive is introduced. This method is not only suitable for railway departments to choose train driving conditions, but also for mechanical manufacturers to design new products. The paper gives the calculation and analysis of the ЭД 1 1 8А traction motor used in diesel locomotive by this method.
