摘　　要：从极对数和裂比对交直轴电感的影响出发,分析了同步磁阻电机的凸极率随极对数和裂比的变化趋势。优化设计了3台不同极对数的同步磁阻电机,研究了不同裂比下3台电机的转矩密度、功率因数和效率,同时兼顾电机的绕组端部长度和体积,提出了同步磁阻电机极对数和裂比的基本设计原则。Considering the influence of the number of pole-pairs and split ratio on the direct-axis and quadra ture-axis inductances, the relationship between the rotor saliency and the number of pole-pairs and split ratio for synchronous reluctance machine （ pairs were optimized, tio designs. Besides, SynRM） was analyzed. Three prototypes with different number of pole- their torque density, power factor and efficiency were inv estigated for different split ra- 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.
