Abstract :
This paper proposes a new stator pole shape having non-uniform air-gap and a pole shoe on rotor pole to minimize the undesirable torque ripple of switched reluctance motor (SRM). Through numerical analysis using finite element method (FEM) and optimization, the proposed pole-shape-optimized stator and rotor having pole shoe are proven to give higher average torque and reduced torque ripple
