This paper presents an analysis of the rotor geometric dimensions influence on the electromagnetic parameters of high speed switched reluctance motor (SRM). This high speed SRM is optimized for automotive application. The paper starts with introduction that describes this type of motor and state of the art of high speed machines. The state of the motor design before this analysis is presented. The next part presents the analysis that was performed in Ansys for case of single pulse operation and

These dimensions include: rotor outer diameter, length of rotor teeth, rotor pole arc and rotor yoke thickness. Finally, the obtained results are presented and commented.
