ansient or starting period is repre-sented by a succession of arcs of circles c, the centers of whichmove from Bq in the moment of start, on the line BqO toward 0,and can be constructed hereby by drawing from the successivepoints Bo, Bi, B2, which correspond to successive moments oftime 0, h, t2 .… … Fig. 19, — Starting Transient of Rotating Field: Polar Form. WAVES AND IMPULSES. From this polar diagram of the rotating field, in Fig. 19, valuesOC can now be taken, corresponding to successive moments oftime, and plotted in rectangular coordinates, as done in Fig. 20.As seen, the rotating field…
