Transient Performance Simulation and Analysis of AC Exciter in Aeronautic AC Power Supply Based on Maxwell 2D

Software package which includes RMxprt for Motor design, Maxwell 2D for electromagnetic computation, Simplorer for complex circuit simulation of Ansoft Corporation has played an role in system simulation fields like a set, but it has disadvantage in design AC exciter in aeronautic AC power supply with armature rotating. There has no input module in RMxprt, therefore this paper establishes two-dimensional transient electromagnetic model for this kind of generator with Maxwell 2D directly and simulates magnetic dimensional distribution, electromagnetic and circuit parameters variation under unloading condition. By contrast with the actual experimental values, it verifies the practicability of the model. Meanwhile, the model can be available to design and optimize this type of machine and other transient investigation analysis.
