all. It is possible to make the commutator longer andthe brush area per set larger, but this is expensive. Equipotential connections are used to a large extent in moderngenerators, however, not for the purpose of reducing the number ofbrushes, but to equalize the distribution of current throughout… … II Fig. 118. Commutator Connections for a 6-Pole Cross-Connected Winding sparking, etc. General practice is to have the full number of brushsets, together with the additional cross-connections, which now equal-ize the currents in the armature sections as well as between thebrushes and are,…
