Abstract

This paper introduces a magnetic circuit model of a mutually coupled switched reluctance machine (SRM) employing full-pitched windings. The model uniquely implements the MMF sources necessary to accommodate complex flux paths through the airgap and stator. The model is implemented in the C⁺⁺ programming language and includes a Gauss-Seidel solver to deal with magnetic saturation. The results are verified through comparison with a finite element solver for a three-phase mutually coupled SRM with six stator poles and four rotor poles. An accurate model and a rapid solution are required for the efficient performance prediction of the mutually coupled SRM
