Electro Static Technology says its new Universal Mounting Brackets allow for fast, easy installation of AEGIS iPRO, AEGIS iPRO-MR, and AEGIS WTG Bearing Protection Rings on large motors. Specially designed brackets attach to iPRO or WTG Rings with screws and have slotted legs (for mounting to motor) that accommodate bolt circles from 2.64 in to 7.79 in in diameter.  Brackets are provided with .5-in, 1-in, and 1.5-in 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.

Available for motor shafts to 30 in in diameter, the AEGIS iPRO prevents electrical bearing damage that could lead to the failure of medium-voltage motors or generators, unplanned downtime, costly repairs, and lost revenues. To facilitate field retrofits, the iPRO split-ring comes in mating halves that aim to simplify installation around the shafts of coupled equipment. The AEGIS iPRO is ideal for medium-voltage motors that drive pumps, compressors, mixers, shredders, conveyors, and other machinery used in mining, food processing, wastewater treatment, petrochemical refining, and other applications.  It is also ideal for protecting the bearings of generators in both utility and on-site power generation systems.

The AEGIS iPRO-MR combines an iPRO Bearing Protection Ring with a shaft voltage monitoring ring in a single compact unit. It helps to ensure 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. The AEGIS WTG Ring prevents electrical bearing damage to wind turbine generators.  Designed for OEM installation or easy up-tower retrofit, the WTG safely diverts up to 120 amps of continuous shaft current at frequencies to 13.5 MHz, as well as discharges to 3000 V (peak).

Without shaft grounding, shaft voltages induced by variable frequency drives (VFDs) discharge through the bearings of motors, generators, and coupled equipment. AEGIS iPRO and WTG Rings have six rows of conductive microfibers that completely surround the motor shaft, providing millions of discharge points for harmful shaft currents and creating a path of least resistance away from bearings to ground.
