An illustration from Cyclopedia of applied electricity : a general reference work on direct-current generators and motors, storage batteries, electrochemistry, welding, electric wiring, meters, electric lighting, electric railways, power stations, switchboards, power transmission, alternating-current machinery, telegraphy, etc., 1916, leaf 136
conductors and the 115 106 DIRECT-CURRENT DYNAMOS commutator at the center, represent the connections at the front endof the armature. For the sake of simpHcity, only a few conductorsare shown in these examples; and it should be noted that in actualdesigns, their number Z attains a much greater… … Fig. 131. Six-Pole Druu Singly Re-entrant Lap Winding winding is around the drum in an anti-clockwise direction, and onthis account it is sometimes called a reirogressive winding to dis-tinguish it from a clockwise, or progressive, winding. The windinghere shown has a commutator pitch of —1, and…
