A New Structure of Stator Pole to Reduce Torque Ripple and Acoustic Noise in Switched Reluctance Motor

Mehdi Babaei, Amir Ahmarinejad

Open publisher page 3 citations

Abstract

Radial forces are the main source of acoustic noise in Switched Reluctance Motors (SRMs). This paper presents new pole tip shape of SRMs for decreasing the torque ripple and reduces radial forces. By using time-stepping finite element analysis (TSFEA), this new structure is simulated numerically in case of single-phase and multiphase excitations to obtain electromagnetic torque characteristic of the motor. Then radial force that affected on stator of the motor calculated precisely from a new analytic proposed method. Simulation results show the high ability of the proposed structure to reduce the two main drawbacks of the motor.
