Abstract: A device may include a first end, a second end, and a coupler configured to extend through an aperture from a first side to a second side of a motor cover. The coupler includes a head portion, a conduit portion extending from the head portion towards the second end, and a first bore axially extending through the coupler. The device may include a brush holder extending through the first bore. The brush holder includes a cylindrical body, a socket at the first end, and a receptacle at the second end. The device may include a first lock nut including a first threaded bore axially extending through the nut. The device may be configured to enable a grounding brush to contact a motor shaft to provide a current discharge path to ground to reduce an erosion of the motor components including the motor shaft and rolling bearing elements.
