Abstract: A system, in certain embodiments, includes a current control brush assembly including a first electrically conductive arcuate housing section retaining a first set of electrically conductive filaments. The first set of electrically conductive filaments extends generally inward along a radial direction. The current control brush assembly also includes a second electrically conductive arcuate housing section retaining a second set of electrically conductive filaments. The second set of electrically conductive filaments extends generally inward along the radial direction. Furthermore, the current control brush assembly includes a hinge configured to facilitate rotation of the second electrically conductive arcuate housing section relative to the first electrically conductive arcuate housing section about an axis substantially perpendicular to a first axial surface of the first electrically conductive arcuate housing section.

Abstract: A flexible conductive static control brush assembly includes first and second brushes disposed on a common backing strip. Each brush includes a plurality of filaments disposed inwardly from opposite edges of the backing strip. Bands overlie outer end portions of the filaments adjacent edges of the backing strip, with the bands covering only a portion of each filament length. The backing strip includes parting lines for tearing to remove an intermediate portion of the backing strip between the brushes to expose the filaments.

Abstract: A shaft current control brush ring assembly includes a cup and a brush ring assembly secured within the cup. The cup is secured to a motor faceplate, within a recess formed in the faceplate by interference fit, or by means of a clamp attached to the faceplate. A slinger can be associated with the brush ring assembly.
