Abstract: Considering the influence of the number of polepairs and split ratio on the directaxis and quadratureaxis inductances, the relationship between the rotor saliency and the number of polepairs and split ratio for synchronous reluctance machine (SynRM) was analyzed. Three prototypes with different number of polepairs were optimized, their torque density, power factor and efficiency were investigated for different split ratio designs. Besides, the endwinding length and machine volume were considered. Finally, the criteria of the number of polepairs and split ratio selection for the SynRM were concluded. Key words: synchronous reluctance machine; number of polepairs; split ratio; inductance; torque density
