Abstract
A comparison of two configurations of a novel two-phase switched reluctance machine (SRM) with no flux reversal in the stator iron is presented in this paper. Conventional SRMs have flux reversals that occur in sections of the yoke during commutation. The two novel SRMs compared in this paper have six stator poles. Each phase comprises of three poles separated by 120deg. The two rotor configurations contain three poles and nine poles, respectively. The comparison includes inductance and torque profiles, self-starting capability and torque ripple, weight, radial forces, core losses and in addition the unique features of the flux-reversal-free-stator SRMs. The results provide an indication of which machine is best suited for a particular application. Data for the comparison is obtained from dynamic finite element simulations
