摘　　要：首先基于磁势矢量分析的方法,分别分析了单相电动机定子磁场的整数次和分数次谐波磁势的旋转方向,总结了谐波磁势的旋转方向与谐波次数、主副绕组间相差的电角度和电流相位差的关系。然后制作了单相电动机的定子谐波磁场转向分析的Excel界面,根据谐波转向的结论编写Excel程序。最后将Excel程序应用于实例,准确获得各谐波磁场的幅值和转向。Firstly the rotation direction of integer harmonic and fractional harmonic of stator magnetic- field of single-phase motor was analyzed based on magnetic potential vector analysis method,and the relationship of magnetic potential harmonic rotation direction with harmonic order,phase shift electrical angle of the main winding and the auxiliary winding,phase difference of current was summarized. Secondly the Excel interface of harmonic magnetic- field rotation direction analysis of single- phase motor stator was made,and the Excel program was wrote based on the conclusion of harmonic rotation direction. Finally Excel program was applied to the prototype,and the magnitude and rotation direction of magnetic-field harmonic was accurately obtained.
