摘　　要：利用绕组函数法量化分析分数槽集中绕组永磁同步电机相对于整数槽绕组电机的自感与互感特性,并推导出通用性规律,得出不同每极每相槽数时分数槽集中绕组永磁同步电机电感参数与同极数整数槽绕组的比值规律。利用有限元分析工具对该类绕组永磁同步电机的交直轴同步电抗进行分析,总结内置式转子磁极结构、带极靴表面式转子磁极结构分数槽集中绕组永磁同步电机的凸极率特性,并通过实验对计算结果进行验证。The winding function theory is applied in this paper to qualitatively analyze the characteristics of the self-inductance and the mutual inductance for permanent magnetic synchronous machines （PMSM） with fractional slot concentrated winding （FSCW） corresponding to the integer slot machines, and the general rule is then derived. The specific values of the inductance between PMSM with FSCW and integer slot winding under different slots per pole per phase are obtained. In addition, the finite element method is applied to analyze the synchronous d-axis and q-axis reactance of PMSM. The characteristics of saliency ratio of PMSM with built-in rotor pole structure and pole-shoe rotor pole structure are summarized. The correctness of the calculation results are verified by experiments.
