| 摘要 | A carbon commutator, for an electric motor, has a plurality of segments forming a brush contact surface and a hub supporting the segments. Each segment has a connector having a terminal for connection of a lead wire, a carbon layer forming the brush contact surface, and a connecting layer fixed to the carbon layer and electrically connecting the carbon layer to the connector. A plurality of micro structures is formed at the interface between the connecting layer and the carbon layer. | ||
