rvals in the armature core and also between all coil ends. Creeping Winding.—Another species of winding, known as a creeping winding is applicable to particular cases. If three adjacent coils, each having a pitch of 120 electrical degrees,be set side by side, they will occupy the same breadth as 4… … In the same way 9coils, each of 160 elec-trical degrees, willoccupy the same an-gular breadth as 8poles. Further, 9 coils of200 electrical degreeswill occupy the sameangular breadth as 10poles. Now of these 9 coils,any three contiguousones are nearly inphase, if wound alter-nately clockwise…
