Abstract
A system, in certain embodiments, includes a current control brush assembly including an axial button having a first electrically conductive housing retaining a first set of electrically conductive filaments. The first set of electrically conductive filaments extends generally inward along an axial direction. The current control brush assembly also includes a radial shaft grounding ring (SGR) coupled to the axial button. The radial SGR includes a second electrically conductive housing retaining a second set of electrically conductive filaments. The second set of electrically conductive filaments is arranged circumferentially around the second electrically conductive housing, and the second set of electrically conductive filaments extends generally inward along a radial direction.
