X$DUltra® 841 IEC


GE’s X$D Ultra® 841 IEC motors build on more than 20 years of

industry experience in extra severe duty motor applications. They are

specifically designed with features that meet or exceed the intent of

IEEE 841-2009, the “gold standard” for the petrochemical and

process industries. What is the IEEE 841-2009 standard, and what does this mean for your application? It means that each X$D Ultra 841 IEC motor delivers even more. Many of the specified materials and components in this standard stem from experience with severely corrosive atmospheres and the necessity for safe, quiet, reliable, high efficiency motors.

Features and Benefits


GEGARD Insulation System


Features Class H insulation materials that increases motor protection

against IGBT drive voltage spikes. Exceeds both the IEEE 841-2009

specification and the requirements of NEMA MG1-31. Our X$D Ultra 841

insulation systems comes inverter duty ready, right out of the box.


Six Star Bearing System ™


A key component in motor operation and longevity is the bearing system.

The GE Six Star Bearing System has been designed to significantly reduce

the potential for bearing failure. Vibration has been reduced to an industry

leading 0.04 ips, reducing a leading cause of bearing failure. Regreasing

consideration has been made easy with extended greasing provisions,

which provides motor users the improved ability to regrease these motors

when they are installed in the application.


Proven Reliability


A five year warranty comes standard with every IEEE 841 X$D Ultra motor

(60 months operational/66 months maximum from shipment). Rugged cast

iron frame, conduit box, endshields & fan cover provide added protection

not found in most motors in the market place.
