摘　　要：虽然Ansoft公司的电机设计RMxprt、电磁场计算Maxwell 2D、混合电路仿真Simplorer等软件包发挥了系统仿真"一条龙"的优势,但对于航空交流电源中交流励磁机的旋转电枢式结构,在RMxprt中没有对应的输入模块,因此直接利用Maxwell 2D软件建立了该类型发电机的二维瞬态场仿真模型,并仿真了模型在空载时的磁场空间分布以及电磁参数和电路参数,与实测值比较,验证了模型的精度。仿真模型可指导该类型电机的结构优化设计和其它工况瞬态特性研究。Although software package which included RMxprt for motor design, Maxwell 2D for electromagnetic computation, Simplorer for complex circuit simulation and etc of Ansoft Corporation had played an role in system simulation fields like a set, it had disadvantage in design AC exciter in aeronautic AC power supply with armature rotating. There had no input module in RMxprt, so this paper directly established two-dimensional transient electromagnetic model for this kind of generator with Maxwell 2D and simulates magnetic dimensional distribution, electromagnetic and circuit parameters variation under unloading condition. By contrast with actual values, it verified the correctness of the model. Furthermore, the model could be available to design and optimize this type of machine and other transient characteristic research.
