nts roundthe ring wires are led to the respective sections of thecommutator. 244-245] ELECTROMAGNETIC INDUCTION 399 Brushes make contact at E and E respectively. Owing to electromagnetic induction all the turns of thearmature in the half ABC tend to produce a current traversingthe armature in the… … Fig. 253. We notice that since the voltage of the machine betweenE and E is that due to all the turns on the half ABC it maybe considerable; the resistance, however, of the armature,being that due to all the turns, is also considerable; hence themachine is not suited to give a very large current.…
