slight decreasein the number of turns could be com-pensated for by increasing the fieldstrength slightly. The three-phasearmature will therefore be providedwith 18 coils, each consisting of 32turns of No. 8 wire. These coils areto be divided into three sets of 6 coils,each of the three sets being… … 2796 DESIGN OF ALTERNATING same thickness of insulation as in the previous examples,thus making the width of the slot 4X .140+3 X .010 + 2 X .040+2 X .060 = .790 in. The depth of the slot will be 8 X .140 + 2 X .040 + 2 X .060= 1.320 in. We will therefore adopt the dimensions \f in. by If in. asthe…
