Omega Products OMAT1.5-18-56CB User Manual

Bearings

There are no sleeve
bearings in our entire
line of general purpose
motors. We use nothing
but heavy-duty oversized ball bearings
on both the DE (drive end) and the ODE
(opposite drive end). It is exactly for this
reason that we can mount our motors in the
“shaft up” or “shaft down” position with no
derating. A shaft slinger keeps moisture and
contaminants from the drive end bearing.
And all of our AC motors have a high tensile
strength steel shaft.

Windings/Insulation

All of our motors have copper windings and
are manufactured with Class F insulation.
This 155°C insulation system gives us
inverter duty capability:

A. Variable Torque Applications:
(Basically, fans and blowers) 5 to 1
speed turndown permitted
B. Constant Torque Applications:
(Basically, all but fan and blower loads)
2 to 1 speed turndown

End Bells and Fan Covers

All of our end bells are heavy duty burnished
(polished) aluminum. Our fan covers are
steel, not plastic.

Junction Boxes

Our large, easy-to-wire junction boxes have
rubber dust curtains designed to keep
foreign particles from entry. These covers
are designed to come apart at an angle to
permit ease of wiring. Most motors are
convertible F1 to F2 and all are rotatable at
90 degree intervals. Conduit holes are
provided per NPT standards.

Motor Leads

All of our leads are both color coded and
numbered per NEMA MG1 Standards.

Omegamation™ general purpose AC motors
are made by one of the leading motor
manufacturers for over 45 years, a world­class accredited supplier with a long history
of quality testing procedures and standards
performed by the finest independent testing
laboratories in the world. Our motors are
made in high quality ISO9001-certified
facilities using only the highest quality
material and manufacturing processes.
All motors are electrically tested in sub­assembly production and again after final
assembly, and come with an ironclad
2-year warranty.

Features and Benefits of AC
Motors from Omegamation

Following are a few of the many reasons
why our AC motors provide the best
combination of quality and performance at
the lowest prices.

Nameplates

Nameplates are said to be the “Window
Of Quality” of a motor. Our AC motor
nameplates are stainless steel to reduce
corrosion and laser etched to provide
permanent markings, and include an
easy-to-read wiring diagram.

Paint

We use an electrostatically applied, rust
proof and scratch resistant paint. The paint
almost seems to become part of the steel
enclosure itself.

Certification

Our motors are CCSAUSCertified. Note the
US stamp. It means that our motor has not
only passed the Canadian Standard
Association requirements, but also the
USA’s UL and ANSI standards, thus giving
them the highest certification standards
you can have for North America. Our
certifications also include CE, CC006A,
and of course ISO9001.

Warranty

Our warranty matches the motors quality in
that it leads the industry in guaranteeing
customer satisfaction. All of our AC motors
have an ironclad two-year warranty and it is
a nameplate-only warranty. That is to say,
the customer sends us the nameplate and
we send him a new motor. No paperwork—
no delay—no waiting for credit based on
a factory inspection—and no questions
asked! Simply call our customer service
department to obtain an AR number for the
nameplate return.
