s room on this armature for two additional windings of thesame type. It is undesirable to spread the winding of a single-phase alter-nator over the whole armature surface. Thus the phase con-stant of a winding spread over the w^hole surface is 0.637 ^^^ thephase constant of a winding spread over ^… … Fig. 179. 100 X 0.637 to 75 X 0.784, that is, in the ratio of 6T).7 to 58.8.It is therefore evident that only a slight increase of electromotiveforce would be obtained by filling up the whole armature surfaceof a single-phase alternator with windings, whereas the armatureresistance, the loss of…
