An example brush holder assembly for positioning a conductive carbon brush in contact with a conductive surface of an electrical device is disclosed. In some aspects, the example brush holder assembly includes a brush holder including a backbone extending therefrom and a removable handle. Further, the removeable handle includes a frame releasably engaged with the backbone and a grip secured to the frame. In some aspects, the brush holder assembly includes a removable catch arm removably coupled to an upper beam and a lower beam of the brush holder assembly. Removal of the catch arm allows the upper beam to be disassembled from the lower beam.

A method for producing a shaft grounding ring includes providing a shaft grounding ring having an annular main body and contact elements arranged on the main body. The contact elements are electrically conductive and plastic-based. The contact elements are configured to establish an electrically conductive sliding contact with a circumferential surface of a shaft or of a sleeve placed onto the shaft. The contact elements are elastically bendable such that the contact elements are configured to preload the electrically conductive sliding contact. Additionally, the method includes thermally preconditioning the shaft grounding ring before use.
