ower-factor on the armature reaction.If the current is in phase with the e.m.f., the current in any coil-side is amaximum when that coil-side is approximately under the middle of thepole (Fig. 326). At this moment the current can produce no flux round thefield magnetic circuit. A moment earlier the… … Fig. 328 If the current lags behind the e.m.f. by an angle ^i, the effect of arma-ture reaction is shown in Fig. 328. The vertical line represents the current/ lagging behind the electromotive force E. This triangle corresponds toBAG in Fig. 318. BH is the excitation X which would produce E on…
