Bearings
There are no sleeve bearings in our entire
line of general purpose motors.
We use nothing but premium
quality SKF brand 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. And
all of our AC motors have a high
tensile strength steel shaft.
Seals
Our motors are protected from moisture and
contaminants by the use of V-ring shaft
seals on both the drive-end and the opposite
drive-end. These motors are name plated
IP54 Enclosure.
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
Castings
Our motors are unicast construction,
meaning the entire frame is cast iron in one
piece, as opposed to two-piece castings that
are welded in the middle of the main frame or
at the point where the feet are attached to the
frame. This unfortunate, cost cutting practice
is becoming more prevalent in our industry.

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 sub-assembly
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.
Metallurgy
Our motors use only high density, FC200
cast iron frames on all sizes starting at 1 HP.
This assures rapid heat transfer from the
core of the motor into the motor’s fins from
which point it is dissipated by the motor’s
fan. Only a select few use this high density
iron which results in longer insulation and
bearing life. Many competitors use less
expensive FC150 or even FC100 iron.
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.
