摘　　要：就《电机学》流行教科书中线圈组和相绕组的磁势谐波成分分析方法,进行了梳理。该分析方法可分为两种:直接法和迂回法。就双层短距绕组相磁势中不含偶次谐波成分,给出了详细的解析证明。证明过程表明,之所以有此结论是因为:N极线圈组和S极线圈组的偶次谐波大小相同、相位相反,从而相互抵消。The analysis methods of coil group's and phase winding's MMF harmonic components in current textbooks of《electrical machines》were carded in this paper.The methods can be divided into two kinds:immediate method and roundabout method.The detailed analytic demonstration of the conclusion that there are no the even order harmonic components in the MMFs of phase winding with two layer short pitch coils.The process of the proof shows that it leads to the conclusion that the even harmonics of the N pole coil winding groups and the S pole coil winding groups are of the same magnitudes,the opposite phases and zero sum.
