摘　　要：<正> 谐波漏抗是交流电机中的一个重要参数,它对电机的稳态和动态性能有很大影响。特别在单绕组变极电机中,由于采用了非正规绕组,谐波含量非常丰富,在分析计算中,其谐波漏抗的精确计算有着更为重要的意义。众所周知,谐波漏磁系数∑S的计算式为: ∑S=sum from v≠1 (K_(ew)/v)~2 (1) 式中v为谐波次数,K_(ew)为绕组系数。当绕组磁势含有次谐波分量,则考虑到转子方的阻尼作用影响后。This paper introduces a new and exact approach for calculating the differential leakage coefficient to the harmonic waves of AC machines. By means of the mathematical inference, an analytical expression of the sum of series sum from a=-∞ to ∞ 1/(n+x)~2 has been proved. It can be applied to the differential leakage coefficient to the harmonics, and get an accurate method to determine the differential leakage coefficient. This method is suitable for all kinds of AC winding. Examples show that the new method is feasible and valuable.
