ABSTRACT:
A brush cage for an electric motor wherein the brush sets are mounted on two assemblies. One assembly is mounted to the frame and the second assembly is mounted to a removable frame end plate, which when removed, provides access to the first assembly and commutator. Each assembly includes an electrically conductive ring upon which the brushes are mounted. The brushes are electrically interconnected through the ring upon which they are mounted. The rings are in a spaced relation to each other along the commutator rotational axis and are on substantially parallel planes which are perpendicular to that axis. The brushes on one ring fit between the brushes on the other ring so as to be disposed around the commutator in an inter-leafed pattern within the space between the two rings.
