Magnetic characteristics modelling for regular Switched Reluctance Machines: Analytical and FEM approaches

In this paper, an analytical approach is used to determine the Flux-linkage characteristic of regular Switched Reluctance Machines (SRMs) considering simple geometry aspects. The proposed method is derived from an 8/6 SRM magnetic characteristic obtained by experimental tests and validated by FEM results. In order to reduce calculation time and expense, regarding simulation and implementation proposes, this analytical functions approach requires only few parameters, normally available or easily measured. An application example for a 6/4 SRM is presented to illustrate its use.
