ABSTRACT:
In an electric motor having a commutator, when a brush wears the associated brushleaf carrying the brush may snag in gap between commutator segments of the commutator, the rotating commutator dragging a bushleaf around into electrical contact with the other brushleaf. To prevent electrical contact being made directly, or via a common commutator segment, a stop is integrally formed with a holder carrying the brushleaves to limit the movement of the brushleaf.
