^. We have determined the elec-tromotive forces due to trans-former action; we must now con-sider those due to rotation. Thesecannot be due to rotation in thefield produced by the rotor itself,nor by the turns BCD (Fig. 432).The only field we need consider is that produced by the turns pig ^24 DEF,… … B^ 047T 2a.
