Abstract
This work deals with the torque ripple minimization techniques of Segmented Rotor Switched Reluctance
Motor (SSRM) for cooling fan application. Torque ripple, acoustic noise and vibration are factors resisting the
segmented rotor SRM. To overcome this, stator and rotor pole modifications along with the effects of laminating
steel material have been analyzed for the performance improvement of the machine. The performance of
the machine with different laminating steel materials such as M19, M850-65A, M890-50d and M43 are compared
with the conventional CR-10 steel material. With respect to pole shape modifications the analysis has
been performed by considering stator pole taper, stator pole arc, rotor segement structure and rotor pole depth.
The results highlight the influence of structural modifications and material properties on the performance of
the motor. The results of electromagnetic analysis disclose that the segmented rotor configuration with M890-
50d material exhibits superior electromagnetic characteristics.
