Helwig Carbon offers several different carbon brushes for grounding applications. Our most popular grounding brush is used as a shaft grounding assembly we call The Bearing Protector that diverts static and induced electric currents in motor shafts away from the bearings, protecting them from pitting and damage. Check out our Bearing Protector which is a brush and holder kit that can be easily installed on the end of the motor shaft.

Shaft grounding for use on Variable Frequency Drives (VFD) is the most popular use of our Bearing Protector. VFDs on both AC and DC motor induce harmful electrical current on the motor shaft that results in damage to the bearings.

Lightning Protection

Helwig carbon brushes are also used to provide a path to ground for lightning on Wind Turbine applications. Low resistant grades of material are used to create a sure path to ground for lightning applications. Our carbon brush and holder assembly is good insurance against lightning damage.
