Abstract
A grounding brush assembly includes a plurality of conductive fibers extending from at least one support, a mounting plate having a first side and a second side and an opening configured to surround a rotatable motor shaft having an axis of rotation, and a plurality of tabs disposed in a circle around the periphery. Each of the tabs extends axially from the first side of the mounting plate and radially toward or away from the axis of rotation to define with an adjacent portion of the first side of the mounting plate a U-shaped bracket. The at least one support is secured against the first side of the mounting plate by the plurality of tabs.
