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.

A grounding brush assembly includes a grounding brush and a brush mounting plate, the brush being provided with a plurality of conductive fibers and a support in which the conductive fibers are housed. The mounting plate is secured to the support and includes a radial portion extending radially outwardly with respect to the support and an axial portion extending axially from the radial portion so as to be spaced radially outwardly from and at least partly radially surrounding the support. The mounting plate also includes at least one collar extending radially outwardly from the distal end of the axial portion.

A motor includes: a lid including an opening; a bracket including a projecting part; and a terminal extending from the projecting part. A part of the bracket is covered by the lid. The projecting part projects from the opening of the lid.
