Abstract
A brush holder assembly for a commutator type electric motor includes a substantially circular base plate of insulating material having a central aperture for receiving the motor commutator. The base plate includes a pair of brush holders for supporting brushes in operative relation to the commutator. A pair of conductive members are embedded in the base plate. Each conductive member has a brush holder mounting portion exposed on both sides of the base plate and a connecting terminal for electrical connection to the corresponding terminal of the stator coils. Power connecting means is provided on the base plate for electrically connecting the terminals of the stator coils to an electrical power source.
