Finite element modeling and dynamic simulation of nonlinear VRM using MATLAB

Due to its many advantages, the switched reluctance machine (SRM) finds several applications such as in the high-speed motor operation or in the power generation. However, unlike many other electric machines, the SRM has the particularity of working in highly saturated regime, which leads to a nonlinear mathematical model. Therefore, this nonlinear behavior requires an iterative process for designing a given structure of machine. In continuation of the previous work carried out by our research team, LGEC, in Electrotechnics Dept. at the University of Constantine1 (ED-UC1), Algeria, we will present in this paper a hybrid methodology based on an analytical preliminary design of a doubly salient 6/4 SRM followed by a finite elements analysis (FEA) using FEMM and MATLAB/Simulink software.
