摘　　要：根据传热学理论,建立了力矩电机电磁稳态运行条件下的三维暂态温度场的计算数学模型,给出了求解域内的基本假设及相应的边界条件,根据电磁场计算,确定了定子铁心与磁极表面的损耗热源分布。以某型力矩电机为例,应用三维有限元法计算了电机温度场的同时,也对定子铁心损耗与转子磁极表面损耗对电机温度场的影响进行了数值分析,计算结果与实测结果相吻合。In this paper the mathematic model of the 3D transient temperature field for a torque motor in the state of steady electromagnetic field is established, and hypothetical conditions and boundary conditions of the solved region are presented. Stator iron losses and magnet pole surface losses are calculated according to the electromagnetic field analysis. A type of torque motor is taken for example, the temperature field is calculated using 3D Finite Element Method, and the losses influence on temperature field is also analyzed by means of numerical method, calculation and practical measurements results are in satisfactory agreement.
