Abstract:
A planar carbon segment commutator assembly comprising:an annular hub comprising electrical insulating material; a plurality of metallic conductor sections supported in an annular circumferentially-spaced array on the hub, each conductor section including a first front projection integrally extending from a front surface of each conductor section; a plurality of carbon commutator segments disposed on respective ones of the conductor sections and defining a flat composite annular front commutating surface, the front projections disposed in cavities in corresponding commutator segments; and the first front projection of each conductor section having a first cross-section parallel to and adjacent the back surface of a corresponding commutator segment and a second cross-section parallel to and spaced axially forward of the first cross-section, the second cross-section having a greater area than the first cross section to prevent withdrawal of the first front projection of each conductor section from its corresponding commutator segment and mechanically locking the commutator segments to their corresponding supporting conductor sections.
