Current diverter ring
The current diverter rings and bearing isolators serve to dissipate an electrical charge from a rotating piece of equipment to ground, such as from a motor shaft to a motor housing. One embodiment of the current diverter is substantially arc shaped with a plurality of radial channels extending there through. A conductive assembly may be positioned in each radial channel such that a contact portion of the conductive assembly is positioned adjacent a shaft passing through the center of the current diverter ring. The arc-shaped body may be particularly useful during installation over certain existing shafts.
