Epoxy for motor-shaft current-grounding ring


The AEGIS SGR Bearing Protection Ring from Electro Static Technology can now be installed with conductive epoxy, eliminating the need to drill bracket holes in the motor’s end bell. For motors controlled by variable frequency drives (VFDs), the SGR channels harmful motor-shaft currents away from bearings and safely to ground.

Unlike conventional grounding brushes, the company says, the ring is maintenance-free and works with virtually no friction or wear for the service life of the motor. While VFDs deliver impressive energy savings, they also induce harmful currents on the shafts of the motors they control. “

The motor shaft and end bell must be clean and free of any coatings, paint, or other conductive material. The installer applies the adhesive to the back side of the SGR, centres the SGR around the motor shaft and holds the ring in place to allow the adhesive to set.
