nd y have no commonfactor, and the winding is therefore simply closed on itself, although elec-trically it is divided into four parallel paths. The brushes iriust be wideenough to cover more than one segment. In general, a winding-step of agives a winding with 2a parallel paths. In this way we are… … Fig. 119 parallel paths. It is easy to see that the series ring-winding previouslydescribed was merely a special case of the series-parallel winding, in which awas made equal to i. We shall confine ourselves to the more important Case in which thenumber of parallel paths is equal to the number of…
