【Abstract】 Considering the influence of the number of pole-pairs and split ratio on the direct-axis and quadrature-axis inductances,the relationship between the rotor saliency and the number of pole-pairs 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 end-winding length and machine volume were considered. Finally,the criteria of the number of pole-pairs and split ratio selection for the SynRM were concluded.更多还原
