交流电机统组磁势的复数分析法

Analysis by Complex Number on the MMF of A.C.Machine Windings

传统电机学在分析交流电机整数槽绕组磁势时所导出的线囵短距系数Ｋｙν、线圈组分布系数见及绕组系数Ｋｗν只涉及量的大小，不能说明各谐波磁势幅值与对应的所在空间位置的关系。本文提出上述系数可应用复数的理论，即采用Ｄｙν＝Ｋｙν它们既反应了对各谐波磁势幅值的影响，又明确了幅值所对应的可用空间电角度表示的空间位置，加强了空间概念，有助于分析电机电枢表面磁势在空间位置分布的规律。用复数取实部求空间任意位置ｘ处磁势大小的方法，进一步使本文所述的复数分析运用简便。

On analyzing the mmf of the integer slots windings of A. C machine by traditional electric machinery, the pitch factor Kyνthe breadth factor of the winding Kqν and thewinding factor Kwν only persent a quantity,and can't show the relation between the crest valbue of the harmonic mmf and its space placement. The paper proposes these factors by complex number,that is,Kyν￣ Kyνthat not only affect theamplitude of harmonic mmf but also confirm its space placement by electrical degree,so thatthe space concept is enhanced.It has more advantages to analyze the regulation of the distributed space mmf on armature surface. The method that takes the complex,s real part tocalculate the mmf's value in any space placement x makes that the complex analysis of thispaper has much advanced in application.
