AGEIS™ Rings

HECO is a trusted supplier of AEGIS™ Shaft Grounding Rings (SGR) to industry. Due to the recent advances and substantial performance gains associated with variable frequency drive (VFD) technology, problems with shaft currents have become increasingly common. Harmful electrical voltages on electric motor shafts can cause premature bearing failure. This risk can be mitigated by bearing protection best practices, as described in the AEGIS™ Bearing Protection Handbook. The AEGIS™ SGR is designed to prevent electrical damage to bearings by successfully channeling the shaft voltages away from the bearing—thus extending the life of an electric motor connected to a VFD. HECO’s knowledge of electric motors, VFDs, and AEGIS™ Shaft Grounding Rings will furnish you with the information you need to guard against potential overheating conditions and subsequent damage to your electric motor.

Underwriters Laboratories (UL) has an approved set of procedures for installing AEGIS® shaft grounding rings inside explosion proof (XP) motors. XP motors with AEGIS® rings installed according to these procedures may be used in Class I: Division 1, and Class I: Division 2 designs. Because shaft grounding devices must be installed inside explosion proof enclosures (as per IEEE 303) for Class I: Division 2, they may not be installed internally or externally in/on a non-XP motor.

HECO is one of a few motor service centers in the country that is UL approved for installing AEGIS rings internally on explosion proof motors.
