The AEGIS SGR Bearing Protection Ring protects the bearings of VFD-driven motors from electrical damage, and the new AEGIS Universal Mounting Kit (U-Kit) simplifies its mounting on most ac motor shafts. Electro Static Technology's kit includes the AEGIS grounding ring and mounting hardware for most motor designs. Ordered based on the NEMA "u" shaft diameter, the kit contains the correct size ring for the motor and four styles of brackets with bolts and lock washers that can be used in various configurations, depending on the contours of the motor's end bracket.
Useful for HVAC service contractors, motor repair shops, plant maintenance departments and original equipment manufacturers, the ring prevents electrical "fluting" damage in the bearing, bearing noise, costly motor repairs/replacements and downtime by safely channeling VFD-induced bearing currents to ground. To simplify the installation of the ring on NEMA frame motors, the brackets in the U-Kit may be mounted on the motor either by drilling and tapping small holes or using AEGIS Conductive Epoxy.
The ring's conductive microfibers are embedded securely in the AEGIS FiberLock channel and completely surround the motor shaft, providing millions of discharge points for harmful shaft currents. This design creates the path of least resistance that effectively diverts these currents away from bearings to ground. The microfibers themselves are engineered for flexibility to prevent breakage. The AEGIS ring is maintenance-free and lasts for the life of the motor.
