Analysis of synchronous reluctance motor using FEM coupled electromagnetic field of Preisach model & thermal field

Summary form only given, as follows. We deal with the analysis in a synchronous reluctance motor (SynRM) using the finite element method (FEM) coupled electromagnetic field of the Preisach model, which is presented to represent the additional thermal source due to hysteresis loss & thermal field. The focus of the paper is the thermal analysis relative to hysteresis loss and copper loss in a SynRM. The finite element model corresponding to variational formulation of the heat conduction problem with convective boundary conditions and thermal sources, for typical element, is given by the following matrix equation: [M/sup e/]d/dt[T/sup e/]+([S/sup e/]+[H/sup e/]+[G/sup e/]+[G/sub m//sup e/])[T/sup e/]=[F/sup e/]+[F/sub m//sup e/]+[P/sup e/] +[R/sup e/].
