Abstract
A brush holder assembly comprises a non-conductive brush holder body covered by a printed wiring board cover. The brush holder body includes a brush cavity for holding a brush, a spring cavity for holding a spring and a shunt wire cavity for holding a shunt wire. The spring is configured to hold the brush in contact with a commutator at a constant brush pressure throughout the entire length of brush travel. The brush holder body and printed wiring board cover are configured to enclose the brush, spring and shunt wire thus protecting the brush, spring and shunt wire.
