EFFECTS OF ADDING ADDITIONAL COILS AND POLES The effects of additional coils may be illustrated by the addition of a second coil to the armature. The commutator must now be divided into four parts since there are four coil ends (see fig. 1-5).The coil is rotated in a clockwise direction from the position shown. The […]

The elementary dc generator and Answers to questions
THE ELEMENTARY DC GENERATOR A single-loop generator with each terminal connected to a segment of a two-segment metal ring is shown in figure 1-4. The two segments of the split metal ring are insulated from each other. This forms a simple COMMUTATOR. The commutator in a dc generator replaces the slip rings of the ac […]
