Electro Static Technology, a division of ITW Inc., announces their ISO 9001:2015 certification following a comprehensive audit performed on-site this summer. Certification recognizes companies that meet and exceed standards of quality and continuous improvement.
“Many of the processes and procedures were already in place. In other areas, the ISO tools used to maintain documentation help us be a better company.”, said Matt Roman, the Engineering Manager and leader of the ISO implementation. “The company as a whole took on this project with vigor and we are proud of this accomplishment. It is our policy to continue improving our processes to meet and exceed our customer’s expectations.”
Electro Static Technology was founded in 1984 and continues to expand its AEGIS® product line. The company designs, develops, and manufactures AEGIS® brand shaft grounding rings and anti-static brush products used to prevent unwanted electrical discharges in motor bearings and to dissipate static charges. Applications include rotating and linear motion machines that are used in industrial and commercial process applications globally.
With 217 exhibitors, almost 400 booths, and 36 first-time exhibitors, the 2017 EASA Convention was a success by any measure.
The AEGIS® sales team was busy at our booth demonstrating the AEGIS® Shaft Voltage Tester™ Digital Oscilloscope, and encouraging visitors to try the scope for themselves. Elsewhere in the booth, we discussed the effectiveness of AEGIS® SGR Rings for low-voltage motors and AEGIS® PRO Series Rings for high power AC or DC motors and medium-voltage motors and generators in channeling harmful shaft voltages away from bearings and safely to ground.
With 6 rows of conductive microfiber brushes and millions of shaft contact points, AEGIS® PRO Series Rings have greater current-carrying capacity than smaller AEGIS® SGRs. They are available in solid- and split-ring versions with optional universal mounting brackets. The PROSLR specially designed for severe environments, with dual O-ring dust/debris barriers that prevent dirt, liquids, and other contaminants from interfering with contact of the ring’s brushes with the motor shaft.

Also on display was the AEGIS® PROMR ring, comprising an AEGIS® PROSL Ring and an AEGIS® SGR monitoring ring separated by a non-conductive phenolic plate. The AEGIS® PROMR provides bearing protection for large motors combined with remote monitoring capabilities. It is ideal for monitoring remotely located or hard-to-access motors.
This year, we had help at our booth from XView Asia Industrial, our distributor for China and the Far East. We were joined by William Wu, Sales Manager, and Desmond Lau, Sales Engineer.
As if the show wasn’t busy enough, our Sales Manager Adam Willwerth made time to star in a video about the benefits, selection, and installation of AEGIS® Rings. To view it, click here.
But promotion of AEGIS® Rings — and the bearing protection they provide — extended well beyond the AEGIS® booth. In

fact, AEGIS® Rings and motors with rings factory installed could be seen in the booths of major motor manufacturers throughout the show. In response to the heightened awareness of VFD-induced bearing damage, a growing number of motor manufacturers now offer AEGIS® Bearing Protection as standard or as mod shop options on their motors.
There are a number of factors to consider when deciding whether to repair or replace a damaged motor. These include (but are not limited to) the age and general condition of the motor, the availability of a suitable replacement (including the size and horsepower), and the energy efficiency of the motor versus a newer motor.
But if you decide that a motor is worth repairing, protecting it from electrical bearing damage makes good sense from both an operational and a financial standpoint. And installing an AEGIS® Bearing Protection Ring — or having your motor repair shop install one — is one of the least expensive “insurance policies” you can buy…especially if the motor is controlled by a variable frequency drive (VFD).
By controlling the speed of motors, VFDs can improve process control and reduce energy usage/costs by 30% or more. But VFDs induce voltages on the shafts of the motors they control — voltages that can damage bearings. And even motors not controlled by VFDs can sustain bearing damage due to stray currents.
Without bearing protection, shaft voltages can discharge through bearings, causing pitting (tiny fusion craters in metal bearing surfaces), frosting (widespread pitting), or fluting (washboard like ridges in the bearing race due to the operational frequency of the drive) and complete bearing failure — sometimes in as little as 3 months!
To protect VFD-driven motors from electrical bearing damage, long-term bearing protection is needed. As proven in millions of installations worldwide, AEGIS® Shaft Grounding Rings channel harmful voltage discharges away from bearings and safely to ground, protecting motor bearings for their full L10 life.
AEGIS® SGR Rings are available for low-voltage, low power motors, while AEGIS® PRO Series Rings are designed for medium-voltage motors, generators, and turbines, as well as large low-voltage AC motors (500 HP or greater) and DC motors (300 HP or greater).
AEGIS® Rings are available in solid rings (for installation before motors are put into service) and split rings (for fast, easy installation on coupled or in-service motors). AEGIS® uKITs include an AEGIS® Ring (solid or split) and a set of mounting brackets that speed and simplify installation on motors with shaft shoulders, slingers, or other end bell protrusions.
Most motor repair shops can install AEGIS® Rings in-house or in the field, using best practices to protect new, in-service, or refurbished motors.
For motors up to 100 HP, an AEGIS® Ring is typically all you need to protect motor bearings and coupled equipment from electrical bearing damage.
Motors greater than 100 HP and medium-voltage motors, however, are subject to high-frequency circulating currents as well as capacitive shaft voltage discharge bearing current. So to adequately protect these motors, install an AEGIS® Ring on the drive end of the motor and an insulated bearing on the non-drive end. For low-voltage motors less than 500 HP, use an AEGIS® SGR. For low-voltage motors greater than 500 HP or medium-voltage motors, use an AEGIS® PRO Series Ring.
Regardless of the type of AEGIS® Ring you install, be sure to thoroughly clean the motor shaft and apply AEGIS® Colloidal Silver to the shaft in the area where the ring’s microfiber brushes will contact it. Or ask your local motor shop to install AEGIS® Rings on any motors they repair for you!

And if you decide that a motor is not worth fixing, choose a new replacement motor with an AEGIS® Ring factory-installed either internally or externally. For a list of manufacturers that offer motors with AEGIS® Bearing Protection Rings factory-installed, click here.
