Abstract
The present approaches provide a current control assembly with a rotor and a stator. The stator includes a drain for channeling contaminants away from the assembly and the rotor includes one or more slots that rotate with the rotor for outwardly slinging the contaminants. In one embodiment, a system is provided that includes the current control assembly having a first ring including a first shaft opening and a first discharge opening. The current control assembly also includes a second ring having a second shaft opening and a second discharge opening, wherein the first and second rings rotate relative to one another, and the first and second discharge openings align with one another to discharge a contaminant. The current control assembly further includes a plurality of conductive filaments configured to transfer current between the current control assembly and a shaft.
