By diverting harmful VFD-induced shaft voltages safely to ground, AEGIS PRO Series Rings protect large AC and DC motors from bearing damage, costly repairs, unplanned downtime, and lost revenue.  Available for motor shafts to 30” in diameter, AEGIS PRO Series Rings are specially designed for high-current applications such as generators, turbines, and medium-voltage motors. Embedded securely in the AEGIS FiberLock channel along the inner circumference of the PRO Series Rings, six rows of conductive microfibers completely surround the motor shaft, providing millions of discharge points for harmful shaft currents and creating the path of least resistance that effectively diverts these currents away from bearings to ground. AEGIS PRO Series comes in solid- and split-ring versions. Solid rings are designed 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. Specially designed Universal Mounting Brackets allow fast, easy installation of AEGIS PRO Series Rings on large motors. These brackets attach to PRO Series Rings with screws and have slotted legs that allow mounting to the motor with a bolt circle of 2.64” to 7.79” greater than the shaft diameter. They are provided with 1/2”, 1”, and 1-1/2” standoff spacers to provide sufficient clearance for shaft shoulders, slingers, or other end bell protrusions. Mounting bolts, flat washers, and lock washers are also included.
