Figure87 is a diagram, similar to Fig. 20, in which the circle representsthe endless circuit formed by the windings on the ring armature.The arrows in Fig. 87 show the directions of the electromotiveforces induced in the various… … Figures 86 and 87 show the state of affairs when the currentin the armature windings is small. When the armature currentis large, the trend of the magnetic flux is altered from that shownin Fig. 86 to that shown in Fig. 88, and the electromotive forces Ii8 DYNAMOS AND MOTORS. in the various turns…
