Switched Reluctance Motor has the main limitation of high torque ripple because of its doubly salient structure. This paper presents the Finite Element (FE) analysis of 5 hp, 655 V, 8/6 Switched Reluctance Motor with rotor pole shaping to reduce torque ripple. It is observed that rotor pole tip radius variation significantly affects torque ripple. Tapered rotor pole having high tip radius results into reduced torque ripple. Rotor pole tip radius is changed from 0 to 5 mm in step of 1 mm and FE analysis is carried out to obtain average torque and torque ripple. It is examined that torque ripple is reduced from 69.1 % to 39.3 % with this technique.
