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$D Ultra
841 IEC motor
delivers even
more.
Many of the specified
materials and
components in this
standard stem from
experience with severely
corrosive atmospheres
and the necessity for
safe, quiet, reliable, high
efficiency motors.
• X$D Ultra 841 IEC vibration
standard of 1.4 mm/sec peak
is 50% less than IEEE 841-2009
standard of 2.03 mm/sec, plus
the total shaft runout does not
exceed 0.025 mm for shaft
diameters up to 41 mm, and
0.038 mm for those greater
than 41 mm for ball bearing
machines. These factors help
extend the life of the motor
and connected equipment.
