Fig. 20. Hence it will not be necessary to modify our assumeddimensions except for symmetry in our drawing. Figs.20 and 21 show the general dimensions of the finishedmachine. Volts drop in the armature = 0.0525 X 40 = 2.1. ELEMENTS OF DYNAMO DESIGN 221 Hence the series ampere-turns to compensate… … Fig. ax. » To compensate cross and back turns will require anadditional 5 % excitation. 5% of 2325 = 117 ampere-turns. Hence IX7 n = —- = 3 turns each core.40 6 This makes a total of about 4 series turns on each core. Length approximately = 3 X 16 = 50 feet, sav of No.2, thus giving 800 cir. mils…
