PROBLEM:
High Shaft Currents Damage Large Motors and Generators
High frequency shaft voltages over 600 volts with currents over 60 amps cause motor and generator failures resulting in hundreds of thousands of dollars in system failure, maintenance and downtime. The use of variable frequency drives (VFD) with large AC motors induce high electrical voltages on the motor shaft. once they exceed the resistance of the bearing lubricant, these voltages discharge to ground (typically the equipment housing), causing fusion craters in the bearings and motor failure.SOLUTION:
AEGIS iPRO - Bearing Protection Ring Technology
The new AEGIS iPRO Conductive MicroFiber Bearing Protection Ring reduces
maintenance and prevents catastrophic failure by safely channeling harmful shaft currents to ground. Using proprietary Electron Transport Technology, the conductive microfibers inside the AEGIS iPRO provide the path of least resistance for damaging bearing currents, preventing electrical damage to motor bearings and dramatically extending motor and generator life.
