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.
