no common factor if the winding is to be singlyclosed. 136 Electrical Engineering If the winding-step is the same both back and front, we have U , Here U and y must have no common factor. If, for example, C7 = 24and ^ = 3, we get 3^ = 5 or 3. The latter value, i.e. 3/ = 3, would not givea singly… … had been wound. The complete armature winding would thus be triplyclosed, that is, it would consist of 3 distinct windings. If, on the other hand,we choose the value y = 5, we get the winding 1—6—11—16—etc., whichis singly closed. This winding is shown in Fig. 120, in which the back…
