Noise and electromagnetic comparison of a three-phase 12/8 and a 12/10 switched reluctance machine

In this work, non-segmented three-phase 12/10 magnetic topology is compared with a three-phase 12/8 design. While higher pole count often implies higher losses, the 12/10 functions entirely on short flux paths. 12/10 core loss implications are; therefore, not immediately clear when compared with 12/8. Pole count also impacts inductance and saliency, parameters which govern all aspects of switched reluctance machine performance. To better understand the non-segmented three-phase 12/10, a comparison is presented with geometrically and magnetically similar three-phase 12/8 and 12/10 switched reluctance machines. The influence of pole count on losses, torque quality, noise and vibration will be compared under specific defined conditions.
