摘　　要：凸极比是影响同步磁阻电机功率因数和转矩性能的关键参数,本文提出了一种基于等效磁路法的同步磁阻电机交直轴电感和凸极比分析计算方法,可以分析转子磁障结构改变对凸极比和电机性能的影响,快速进行同步磁阻电机的转子结构优化设计。为验证磁路法的可靠性和准确性,论文采用有限元法对一台30 kW同步磁阻电机进行了仿真分析,计算电机在不同转子磁障层数、不同磁障宽度、不同径向磁桥数量时的交直轴电感值、凸极比和输出转矩,并与磁路法得出的结论进行了对比。Saliency ratio is a key parameter that affects the power factor and torque performance of Synchronous Reluctance Motor(SynRM).This paper presented an analysis and calculation method for the quadrature-axis inductance and saliency ratio of SynRM based on the equivalent magnetic circuit method.It could analyze the influence of rotor magnetic barrier structure changes on saliency ratio and motor performance,and quickly optimize the rotor structure of SynRM.In order to verify the reliability and accuracy of the magnetic circuit method,the paper used a finite element method to perform a simulation analysis on a 30kW SynRM,and calculated the q-axis and d-axis inductance values,saliency ratio and output rotation of the motor under different rotor magnetic barrier layers,different magnetic barrier widths and different radial magnetic bridge numbers,and compared with the conclusions obtained by the magnetic circuit method.
