The addition of a commutator changes curve of Fig. 26, so that only positive valuesare given as in Fig. 28. Obviously, the generated by a single wire isinsufficient for practical purposes. Hence, the mod-ern dynamo has an armature wound with a greatmany wires. A large number of such active wires Commutation 65 are so connected that their voltages are , since the wires are evenly distributed aboutthe drum, or armature core, the commutator is con-structed of many segments which are connected tothe winding at regular intervals.
