torque ripple minimization of switched reluctance hub motor

Abstract

Switched reluctance motors (SRM) are gaining importance in the variable speed market due to their simple and rugged construction. To design the motor for higher performance, the estimation of their performance is essential at the time of their geometric design. In this project, finite element analysis (FEA) is used to calculate their performance parameters from their geometry. The dynamic performance of SRM is predicted by MAGNET software using the calculated parameters. The circuit coupled finite element analysis is used to estimate the dynamic performance of the SRM. The torque ripple is the one of the major problems in the Switched Reluctance Motor. In this project, a detailed investigation is made to decrease the torque ripple by increasing the stator and rotor pole shoes
