us formed betweeneach pair of coils are connected to the copper strips of the com-mutator. Fig. 18 represents the mode of winding this wire onthe ring, only a few turns, however, being shown. The commutator consists of copper strips equal in number tothe armature coils, placed radially edgewise… … Fig. 17. Fig. 18. face of the commutator rest bundles of soft iron wire, by whichthe currents generated in the armature coils are conducted tothe external circuit. As the armature is rotated between thepoles of the field magnets, currents of electricity are generated.These machines are also…
