针对8/6极开关磁阻电机，采用电磁场有限元的方法，研究不同绕线方式所形成的不同磁极分布对电机自感和互感的影响。研究表明：电机各相自感最大值与磁极分布的对称性有关，其差值可达30％左右；不同磁极分布下，各相间互感变化规律相差很大，仅有NSNSNSNS分布的电机各相间互感具有良好的一致性，且全为正值；互感相对自感的大小亦与磁极分布的对称性有关，对于反对称磁极分布的SRM，互感平均值不到自感平均值的10％，而正对称磁极分布SRM，互感平均值接近自感平均值的40％。

For the four phase 8/6 switched reluctance motor , using the finite element method of electromag-netic fields , researched the impact of different winding connection type and different poles distribution of SRM on self inductance and mutual inductance .The studies have show that: each phase maximum value of self inductance is associated with poles distribution symmetry of SRM , and its difference is up to 30%;For different poles distribution of SRM , each mutual inductance of phases has big difference , only the mutual in-ductance of SRM with NSNSNSNS distribution has good consistency , and they are all positive .The relative proportions between mutual inductance and self inductance is associated with the symmetry of poles distribu -tion, for the antisymmetric SRM , average value of mutual inductance is less than 10% of average value of self inductance , but for the symmetric SRM , average value of mutual inductance is approaching 40%of av-erage value of self inductance.
