摘　　要：本文针对改制谐波励磁发电机时,由于原产品型号或生产年代不同而产生的性能差异较大的情况,提出根据发电机铁芯的极弧系数αP 进行电枢绕组结构选择,给出了进行谐波绕组可靠匝数计算的实用公式 W_(3K)=(W_1·U_(BH)·(δ_m/a)^(1/2))/(m_3·U_1·αp^3·K_(r3)),并讨论了凸极铁芯参数对谐波励磁发电机性能的影响及其处理方法.The improved harmonic excited generator differ in their type and times,so their functions have great difference.In view of this situation,this essay raises a select of armature winding according to the iron cores pole-arc factor αP,gives a practical formula about the account of the reliable coil:W_(3K) =2.4(W_1·U_(BH)·(?))/(m_3·U_1·αP^3·K_(p3)),discusses the effect that is produced by convex iron core and the way of handling.
