AEGIS PRO Series rings from Electro Static Technology are designed to divert harmful VFD-induced shaft voltages safely to ground, protecting large AC and DC motors from bearing damage. Available for motor shafts up to 30 inches in diameter, the rings, available in solid and split versions, are specially designed for high-current applications such as generators, turbines and medium-voltage motors. Solid rings are made for installation on new or repaired motors prior to their installation. Split rings come in mating halves that simplify field installation around the shafts of in-service/coupled motors. The PRO SLR Ring features O-ring barriers that prevent the ingress of dust, debris and excessive contamination that could lessen contact of the ring’s conductive microfibers with the motor shaft. 866/738-1857; www.est-aegis.com.
