This paper presents the performance computation of three-phase 6/4 poles Switched Reluctance Motor (SRM) with amorphous alloy core using transient Finite Element Analysis (FEA) in which the magnetic field is combined with a driving circuit. In order to minimize torque ripple in SRM, this paper proposes not only optimal combination of stator pole arc and rotor pole arc but also the turn-on and turn-off angles using parameterized transient FEA and response surface methodology (RSM). The magnetic fields distribution, the winding flux linkage, the phase inductance curve, the iron losses and the torque characteristics of the prototype SRM at low-speed are investigated. All studies show that the prototype SRM is potential to apply in home appliance applications.
