Influence of iron powder core on the switched reluctance motor performance enhancement

Soft Magnetic Composite (SMC) materials possess isotropic magnetic and thermal properties, very low eddy current loss and relatively low total core loss at medium and higher frequencies. This paper presents the application potential of iron powder SMC in switched reluctance machine (SRM) and its performance enhancement. The results of extensive finite element simulation and experimental validation of the proposed fabricated prototype are delineated. The study concludes that the use of SMC as magnetic core of a switched reluctance motor enhances its thermal and vibration characteristics in comparison with the conventional lamination counterpart.
