    摘要: The invention comprises an electrographitic commutating brush having a low electrical resistance characteristic in a direction substantially perpendicular to a working face of the brush, and a high electrical resistance characteristic in the direction of brush movement relative to a commutator. To produce such characteristic resistances, the body of the brush is provided with voids or cavities controlled in size and shape, and oriented to have elongated dimensions in planes perpendicular to the working face of the brush, and in planes perpendicular to the direction of relative brush rotation with the commutator.
