Investigation of power losses in switched reluctance motors due to rotor eccentricity utilizing FEM

In this paper, the effects of rotor eccentricity (RE) on power losses in switched reluctance motor (SRM) with driver is studied. Two major asymmetrical faults namely as; dynamic eccentricity (DE) and static eccentricity (SE) are implemented with different percentages of eccentricity in a 6/4 SRM. Then different kinds of effective factors on total losses such as; flux density, flux linkage, ohmic losses, hysteresis losses, eddy- current losses and iron losses are evaluated by Transient Finite Element Method.
