Abstract

This paper presents the switching angle and the 1/2-phase hybrid exciting method to minimize torque ripple in the 6/4 Switched Reluctance Motor (SRM). The inductance in SRM is dependent on rotor position and current. Therefore, the inductance profile is expressed as an approximate function based on FEM data. And then, the dynamic characteristics are simulated by Matlab simulink using the derived inductance function. The torque ripple resulting from single phase exciting and 1/2-phase hybrid exciting is compared.
