Coupled field finite element analysis of switched reluctance motor with soft magnetic composite material for thermal characterization

This paper describes a more precise technique for thermal analysis due to joule heat loss in switched reluctance motor with soft magnetic composite material (SMC) by two dimensional (2-D) coupled field finite element analysis. The finite element model is solved in tandem by a cascaded procedure comprising electromagnetic and thermal analysis. The results of the coupled field finite element analysis of two configurations viz (a) Switched reluctance motor made of lamination sheet steel (SRM-M19) and (b) Switched reluctance motor made of soft magnetic composite material (SRM-SMC) are presented.
