The structure and principle of synchronous reluctance motors ( SynRM) were briefly introduced. The relationship between main parameters of rotor such as number of barrier layers, the percent of barriers, the width of rib,and machine's induction and saliency ratio was investigated using finite-element software. These works would provide reference for the design of SynRM. The SynRM's characteristic of inductance and torque under different current load were also investigated, the simulation results indicated that the inductance and the current angle of Maximum Torque Per Ampere ( MTPA) was influenced by current load. Finally, the prototype was made according to the result of simulation and the simulation results were proved to be correct by the experiments.%简要介绍了同步磁阻电机的结构及工作原理. 通过有限元软件分析转子主要结构参数,如气隙磁障层、气隙占比、磁肋宽度对电感和凸极比的影响,为同步磁阻电机的转子最优设计提供参考. 同时分析了不同负载电流下电机的电感和转矩特性,结果表明电机的电感随负载变化,且最大转矩电流角随着负载电流的增大而增大. 最后根据仿真结果试制样机,通过试验验证有限元仿真的正确性.
