n(Fig. 942) the field magnetsare fixed, and the coils rotatein the direction of the arrow.Some machines, however, aredesigned so that the coils arefixed and the field magnetsrotate. For the e.m.f. in theabove case to remain un-changed, the magnets wouldhave to rotate in a direction opposite to that… … fig. 943.- -Rotor connections for a six-polealternator. to arrange the conductorsupon the outside only ofthe iron core. In Fig. 943an arrangement of thirty-sixconductors round the surfaceof the rotor is shown. Theseare supposed to be connectedat the front as shown bythe thick lines and at theback…
