The AEGIS® iPRO-MR is an AEGIS® Shaft Grounding Ring and a shaft monitoring ring in one, ensuring optimum uptime and reliability of large motors and generators in critical applications. The iPRO-MR is ideal for the protection of motors in remote locations that cannot be easily monitored or maintained.

The rugged, highly reliable, and maintenance-free split-ring AEGIS® iPRO prevents damage that could otherwise cause generator or motor failure, unplanned downtime, costly repairs, and lost revenues.  Available in a range of sizes to accommodate even the largest motor shaft diameter, the iPRO shaft grounding ring comes in mating halves to facilitate field retrofits on coupled equipment. With multiple rows of conductive microfibers completely surrounding the shaft, it provides millions of discharge points for harmful shaft currents and is ideal for high-current motors controlled by variable frequency drives (VFDs), including low-voltage motors over 500 HP, medium-voltage motors, power generators, and OEM systems.

If not diverted, VFD-induced high-frequency shaft currents and circulating currents discharge through motor or generator bearings, or through coupled equipment, causing severe electrical damage.  Bearing failure and catastrophic generator/turbine failure can result in as little as six months or less. Compatible with current-monitoring equipment, the AEGIS® iPRO encircles the motor shaft with patented microfibers, providing a path of least resistance to ground and effectively diverting these currents away from bearings.

The AEGIS® iPRO is the longest-lasting and most effective shaft grounding system on the market available today.  It is engineered to handle high frequency shaft currents up to 100 MHz. It can be installed as part of a preventive maintenance program whenever bearings are replaced.
