摘要
磁通切换型磁阻电机(flux switching motor,FSM)是近年来出现的一种新型双凸极无刷电机,独特的结构和工作原理使其建模与动态仿真成为难点。为了较准确地研究其电磁特性,基于傅里叶级数和数值拟合的方法,构造了FSM的高阶连续非线性电感函数,据此建立了整个FSM系统的数字仿真模型,分析了其动态特性;设计了一台2.2kW、8/4极结构FSM样机,进行了实验研究,实验和仿真结果对比表明:所建立的非线性模型能够较好地反映FSM系统的实际工作特性,为该电机的设计、性能分析以及控制策略等提供了参考。
A new class of doubly-salient brushless motor, namely, flux switching motor （FSM） is emerging in recent years. Due to the unique structure and operation principle, the modeling and dynamic simulation of FSM become a difficult issue. To describe the electromagnetic characteristics of FSM accurately, the high rank continuous nonlinear inductance function of FSM model was formulated based on the method of Fourier expansion and numeric fitting. The numeric model for the whole FSM driving system was established and the dynamic performance was investigated. A 2.2 kW 8/4 pole prototype FSM was designed and the experiment was done. The simulation and experimental results demonstrate that the nonlinear model established can better reflect the practical operation characteristics of FSM drive system. It provides reference for machine design, performance analysis and controlling strategy design for FSM.
