摘　　要：对于航空交流电源中交流励磁机的旋转电枢式结构,有限元电磁分析的研究较少。文章以此为研究对象,阐述应用M agnet软件建立二维瞬态运动场仿真模型的原理和步骤,并仿真了交流励磁机在空载工况下的磁场空间分布、电磁参数、电路参数,通过实测对比,证明了模型的实用性,该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。Since few methods adopted finite element method to analysis AC exciter with armature rotating structure of aeronautic AC power supply ,it was taken for research object in this paper. It stated the principle and process of two - dimensional transient field simulation modeling with Magnet software. Furthermore, it also simulated field distribution, electromagnetic and circuit parameters under unloading for AC exciter. With contrast to actual values, the model was proved available to design and optimize this type of machine and other transient characteristic research.
