we now know that the field-magnet can reach a strengthbeyond which no additional current can make it any stronger.That being so, the great starting-power is due simply to thegreat current in the armature, and that can be made equally greathowever a machine is excited. If it is excited up to 16 or… … Fic. 118 Field-Magnet Excitation possible tlux density, and the armature should be large and, as amagnet, very powerful, so that when the normal current is exceededthe field is actuallyweakened by thedux from the arma-ture poles.
