DYNAMO-ELECTRIC MACHINE DESIGN. 2469 may be found by applying formula 592. If only one mag-netic circuit is considered, it will be necessary to take 60volts as the E. M. F. across its terminals, because the twocoils are to be connected in series. 3691. In the four-pole dynamo of Fig. 1364 {a),… … Fig. 1364. magnetic circuits to be considered in determining the ampere-turns are only two. Another disposition of the field frameand yokes, as at {d), does not change the number of circuitsthrough the armature, or the distribution of the lines offorce; yet in this case there are evidently only two…
