ANALYSIS AND CHARACTERIZATION OF A SWITCHED RELUCTANCE MACHINE USING SOFT MAGNETIC COMPOSITE MATERIAL

Abstract

Soft magnetic composite (SMC) materials characterized by three dimensional isotropic ferromagnetic behavior and very low eddy current losses find utility in complex geometry electrical machines due to flexible machine design and assembly .The suitability of soft magnetic composite material in switched reluctance motor (SRM) has been investigated through static, dynamic, thermal, vibration and acoustic noise characterization. Extensive Finite Element (FE) and coupled field analysis study has been carried out on three configurations viz (a) SRM made of Sheet Steel (SRM-M19)(b)SRM made of Soft Magnetic Composite material 500 (SRM-SMC500) and (c)SRM made of Soft Magnetic Composite material 1000 (SRM-SMC1000) and few test results are presented.
