Abstract
A method of making a carbon commutator is provided. The method includes the steps of providing a planar substrate having a series of current-carrying regions; providing a carbon base having a brush-contacting surface and a second opposite surface; substantially covering the second surface of the carbon base with a conductive plating to form an unslotted commutator body; applying a conductive bonding layer to the conductive plating; bonding the unslotted commutator body to the substrate; and cutting corresponding slots in the commutator body to form a series of commutator segments.
