ABSTRACT:
A commutator assembly for a dynamoelectric machine with metallic brushes has a plurality of composite carbon commutator bars retained on a generally cylindrical molded core with radial extensions and retaining lips at each axial end. A hook member for each bar has a U-shaped portion clamping one end of the bar and trapped in the molded core for retention of the bar against migration due to tangential brush force and a hook portion projecting outward for armature wire connection.
