that this is the same formula as that usedfor the bipolar drum winding, in which both pitches weregiven the same direction (formula 483), with the additionof the term/. (See Art. 3148 and Fig. 1171.) 1998 APPLIED ELECTRICITY. 3161. Fig. 1175 is a diagram of a four-pole wave wind-ing, in which y =… … Fig. 1175. This holds true just as the two-circuit multipolar rings,whatever the number of poles of the field. The advance of this winding is in the same direction asthe pitch. If +2 had been used in the formula, 38 conduct-ors would have been required, and the advance would havebeen opposite in…
