Abstract
A combination motor brush support and electromagnetic suppression circuit comprises an assembly having a base which is affixable to a portion of a motor housing and which supports all components requiring precise mechanical alignment, including motor brushes, brush guides and brush springs. The base can also support the choke coils, and at least some of the capacitors of the noise suppression circuitry. The base includes a terminal support board affixed to, and projecting therefrom. The terminal support board has at least one of the capacitors of the noise suppression circuitry retained thereupon, and provides a set of motor contact terminals which are in electrical communication with the motor brushes supported on the base. The support member of the present invention functions as its own assembly tool for supporting and retaining the coils, capacitors, springs and the like.
