摘　　要：建立了直流电磁铁的温度场模型 ,通过对温度场的分析 ,建立直流电磁铁的热路数学模型 ,研究了电磁铁中热的流动 ,与温度场的计算结果进行对比 。Thermal field model DC of electromagnet was built in this paper. Mathematical model of thermal circuit was built by analyzing thermal field. The heat flow in a DC electromagnet was simulated. The result of thermal circuit was compared with that of thermal field. An experiment was made to test the results of thermal field and thermal circuit.
