OV at ratedload. If the machine is shunt-wound, the resistance of the shunt rheostatmust be capable of reducing X^ ampere-turns to A^ ampere-turns. And ifthere are to be neither series turns nor shunt regulator, the drop from ratedload to no load would be OE,^ — OF at constant speed. Applying this… … Ampere TutTis per Pair of Poles Al Xi A l-^a-^^. Fig. 153. Calculating Ampere-Turns Required toCompensate for Distortion of Useful Field inductors per slot, and the third the current per inductor, we set off, there-fore, 6,270 ampere-turns on each side of the point A3 (Fig. 151), and obtainthus the…
