inning of the next element connected to the firstone is called the winding space, or simply pitch. This pitch mayeither be measured by the number of inductors passed over or by thenumber of commutator bars passed. In the former case it is desig-nated as winding pitch, y, while in the latter case it… … Fig. 111. Ring Winding for 4-Pole Machine 100 CALCULATIONS 91 The first type, shown in Figs. Ill and 112, forming in itself asingle closed helix, is unaffected by the number of poles (2p); bymerely placing 2p sets of brushes on the surface of the commutatorat equal distances apart, the winding is…
