Flux-linkage characteristics models for Switched Reluctance Machines

This paper discusses how the magnetic characteristics of Switched Reluctance Machines (SRMs) are obtained by experimental, analytic and FEM modelling. Two analytical approaches are used to determine the Flux-linkage characteristic of Switched Reluctance Machines considering simple geometry aspects. The proposed methods are derived from a regular SRM magnetic characteristic obtained by experimental tests and validated by FEM. In order to reduce calculation time and expense, regarding simulation and implementation proposes, these analytical functions approaches require only few parameters, normally available or easily measured. The developed model of the first approach is presented and the second approach concepts are illustrated with a 6/4 SRM flux-linkage characteristic.
