    AEGIS® PRO SERIES RINGS PROTECT LARGE MOTORS AND GENERATORS FROM SHAFT VOLTAGE BEARING DAMAGE

    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.

    If not diverted, shaft voltages produced by variable frequency drives (VFDs) discharge through the bearings of motors, generators, and coupled equipment.  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.  The AEGIS® PRO SLR Ring is specially designed with
    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.

    The AEGIS® PRO-MR combines a PRO Bearing Protection Ring with a shaft voltage monitoring ring in a single compact unit.  It ensures maximum uptime and reliability of large motors and generators in critical applications, and enables real-time monitoring of shaft voltage levels on motors in remote or hard-to-access locations.

    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.
