Abstract
A major problem of switched reluctance motors (SRMs) is torque ripple, which causes undesirable acoustic noise and vibration. It is caused by the saliency of the stator and rotor. In this paper, the geometry for low torque ripple is researched and a motor having notched teeth is proposed. Its characteristics are simulated by finite-element method (FEM) analysis and compared with SRMs having conventional shape.
