AEGIS® Rings Now Factory-Installed on Explosion-Proof Motors
Marathon Motors and AEGIS® Team Up to
Launch New Line of UL-Listed Explosion-Proof
Motors with Factory-Installed Bearing Current
Protection (“BCP”) System, Featuring
AEGIS® Shaft Grounding Rings
Marathon motors, a Regal-Beloit company based in
Wausau, WI, is proud to announce an industry leading
enhancement to its extensive line of NEMA Premium
Explosion Proof motors. With the growing emphasis on
energy savings, specifying and process engineers as
well as plant maintenance personnel have turned to
variable frequency drives (VFDs) to reduce energy
usage of electric motors in their facilities. While energy
savings are important, process reliability, uptime and
safety (particularly in hazardous locations) are critical.
It is well documented that VFD-sourced Common Mode
Voltage (CMV) can contribute to bearing failures in
drive/motor systems. Unfortunately, unexpected
bearing failure can offset much of the savings initially
anticipated by the use of VFDs. Effective shaft
grounding helps prevent the destructive effects of CMV
in these critical applications, facilitating maximum
energy savings and reliability.
Marathon Motors’ new XRI® motors are the world’s
first Division 1 explosion-proof motors with AEGIS®
Bearing Protection Rings factory installed internally.
See pages 79-80 of the Marathon Motors Product
Catalog.
Marathon’s unique design, combined with AEGIS® SGR
technology and Marathon’s work with Underwriters
Laboratory (UL), mitigates the risk of bearing damage.
Installation of AEGIS® SGR inside the motor enclosure
(outside the “flame path”) is in full compliance with UL
Policy. Marathon’s “BCP” System, featuring AEGIS®
SGR, meets all UL requirements, while protecting the
motor bearings.
Available across the entire product line, and in stock
through 50 HP, the Marathon “XRI Explosion Proof
Severe Duty” motor with “BCP” provides maximum
energy savings potential when used with VFD’s,
enhanced reliability and uptime, and the “peace of
mind” end users demand from their motor/drive
systems. Marathon is the only supplier of Division 1,
Class I and II Explosion Proof motors with factoryinstalled AEGIS® long-term bearing current protection
from VFD-sourced damage!
The Marathon XRI Severe Duty Explosion Proof motor
is UL Listed and CSA Certified for use in virtually any
process application. The product features cast iron
construction, epoxy interior and exterior paint,
Max Guard insulation system, precision balance,
thermostats and a generous 3 year warranty.
Marathon’s Bearing Current Protection (BCP) System
combines patented AEGIS® Bearing Protection Ring
technology and Marathon’s work with Underwriters
Laboratory (UL) to mitigate the risk of bearing damage. The BCP System includes factory installation of
the AEGIS® Ring inside the motor enclosure (beyond
the flame path) to protect motor bearings while
ensuring full compliance with UL policy and all UL
requirements.
Are you tired of sacrificing energy savings or long
bearing life in the name of safety? With Marathon’s
new line of XRI Explosion Proof NEMA Premium
Motors with AEGIS®–installed “BCP”, you’ll never
have to compromise again.
Since Division 1 Hazardous Locations environments
involve the transportation and processing of large
volumes of material, the cost of motor and process
downtime due to bearing damage can be significant.
With Marathon’s new BCP motors, the energy savings
of VFD operation, long life and sustainability and the
safety of a UL Listed/CSA Certified product can be
yours today. You don’t have to compromise any
longer…Insist on the FIRST AND ONLY Explosion
Proof motor with Bearing Current Protection:

Are you tired of sacrificing energy savings or long
bearing life in the name of safety? With Marathon’s
new line of XRI® Explosion Proof NEMA Premium
Motors with AEGIS® Bearing Protection Rings you’ll
never have to compromise again.
Marathon’s new Hazardous-Duty™ XRI® ExplosionProof Motors equipped with AEGIS® Bearing
Protection Rings provide long, trouble-free life in
explosion environments such as petrochemical
processing (top left), paint manufacturing (top
center), oil drilling operations (top right), as well as
other applications such as those shown below.
Designed for hazardous environments, they are ideal
for oil and gas drilling applications; natural gas fracking;
and petrochemical transfer and processing of products
such as solvents, varnishes, dilutants, gasoline,
alcohol, dyes, perfumes, chemical products, and
agents used in the manufacture of plastics.
They are also ideal for facilities involved in the filling of
containers for natural gas, propane, and other volatile
gases, storage facilities for compressed gasses such
as LNG, and livestock farms/breeding facilities.

Natural gas fracking
Designed and manufactured with epoxy coated
surfaces inside and out, these motors are perfect for
harsh marine environments (such as ships and drilling
platforms) as well as high temperature and humidity
environments such as chemical plants, refineries, and
wastewater treatment plants.
Coal preparation
Marathon XRI® Explosion-Proof Motors are perfectly
suited to applications involving high levels of airborne
dust as well — applications such as the transfer,
grinding, or storage of combustible organic or
inorganic materials such as coal, magnesium,
aluminum, sulfur, cellulose, cereals, carbon, wood,
resins, sugars, starch, flax, polystyrenes, fertilizers,
pharmaceuticals, fireworks, or munitions.
Because often these explosion-risk environments
involve the moving and processing of extremely
large volumes of material, the cost of motor and
process downtime due to bearing damage can
often be staggering. With Marathon’s new Bearing
Current Protected XRI® Explosion-Proof Motors you
can enjoy the efficiency of a NEMA Premium motor,
the energy savings of VFD operation, the long life
and sustainability of AEGIS® Bearing Protection,
and the safety of a UL Listed/CSA-Certified
explosion-proof motor.

Karen Cambridge — Color Her Rad
Karen Cambridge, Key Account Executive for
Electro Static Technology, likes to run. She also
likes fun. So when the opportunity to run through
a gauntlet of exploding die packets presented
itself, Karen jumped at the chance.
Billed as “the race that’s been ruining all other
5Ks,” the Color Me Rad Maine is not your average
5K. In fact, there is nothing conventional about it.
Sponsored by the local YMCA and held on August
24 in Brunswick, Maine, the Color Me Rad sent
runners along a course lined by volunteers with
exploding packets of brightly colored, gluten-free
cornstarch. After making their way through clouds
of colorful dust, runners crossed the finish line
looking like they had been mugged by a rainbow
— totally Rad!
Karen completed the race “with flying colors,” and is
looking forward to running it again next year.
