Abstract

An armature includes a plurality of equalizing connectors for permanently electrically connecting pairs of commutator segments that should have the same electric potential, so that each of the pairs of the commutator segments that should have the same electric potential has a substantially equal electrical potential. In one embodiment, at least one pair of adjacent coil portions share a common slot.
