Shaft grounding ring

This Shaft Grounding Ring Protects Medium-Voltage Motors and Generators from Bearing Failure.

09/29/2010


The AEGIS iPRO Bearing Protection Ring from Electro Static Technology extends the life of medium-voltage motors and improves the reliability of systems in which they are used by safely channeling harmful electrical currents away from bearings to ground.  Specially designed for high-current applications, the AEGIS iPRO protects generators, turbines, and medium-voltage motors against electrical bearing damage.

The AEGIS iPRO prevents damage that could otherwise lead to generator or motor failure, unplanned downtime, costly repairs, and lost revenues.  It is available in a range of sizes to accommodate generator/motor shafts up to 30 in. in diameter.  To facilitate field retrofits, the iPRO split-ring comes in mating halves that simplify installation around the shafts of coupled equipment.  Common sizes (for motor shafts between 2.5 and 12 in. in diameter) are typically shipped within five days.

If not diverted, shaft voltages induced 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 iPRO, 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.

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 many other applications.  It is also ideal for protecting the bearings of generators in both utility and on-site power generation systems.

Compatible with current-monitoring equipment, the AEGIS iPRO is engineered to safely divert high-current and high-frequency dv/dt shaft currents and works in the presence of oil, dirt, grease, or other contaminants.  As part of a preventive maintenance program, it can be installed whenever bearings are replaced.
