ABSTRACT:
A brush holder assembly which utilizes an insulated brush card and a bridge means to define a receiving aperture for a brush element. A pair of legs and a connecting element serve to define the bridge means and a constant force spring is retained by the legs so that as the brush is received within the aperture, the spring will partially uncoil and the uncoiled portion of the spring will conform to the profile of the brush. The bridge means also includes a guideway by which the brush is restricted against lateral movement during its use in a motor or generator unit.
