ABSTRACT:
A brush holder assembly for mounting on an electric machine casing. The brush holder assembly includes a brush, a brush guide that supports and guides the brush for travel, a spring for biasing the brush in a direction toward a commutator, and an electric insulator mounting for mounting the brush guide on a casing. The electric insulator mounting has electric insulator elements containing grooves engaging the side edges of the brush guide to support the brush guide and the brush in spaced relation to a casing when the brush holder assembly is mounted thereon. The brush guide has at least one wiring tab. Several forms for attaching the insulator elements to the casing are disclosed including threaded fasteners; integral grommet formations of the insulator elements; and the insulator elements being integral formations of the casing.
