General Electric NEMA/IEC AC Motors
X$D
Ultra® NEMA Premium Efficiency - TEFC
 The
X$D Ultra® family of products ranges from 1-300 HP and is built to
the highest standards to maximize your return on investment. X$D Ultra is a
complete cast iron motor exceeding NEMA Premium® Efficiency standards.
The Six Star Bearing System™ ensures long bearing life and is complemented
by an overall vibration of 0.04 ips (inches per second), which is half of IEEE-841
standards. The X$D Ultra also incorporates the GEGARD2000™ insulation
system which has the ability to withstand repeated 0.1 microsecond rise time/2000
volt spikes for 460 and 575 line voltages. All motors are inverter compatible
and have the speed range capabilities stamped on the nameplate.
Industries: Oil & Gas, Power& Energy, Mining & Minerals, Water & Wastewater,
Cement, Pulp & Paper, Metals, Chemical
Features and Benefits
-
GEGARD2000 Insulation System
Integral to motor life and reliability is a
robust insulation system. The GEGARD2000 system utilized in
Ultra™ gives
a wide thermal margin between the insulation components and
designed operation temperatures. All
components
except motor leads have been selected using Class H materials,
while the motor temperature is kept below Class B temperature rise.
-
Six Star Bearing System ™
Another 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
-
Meets or Exceeds New NEMA Premium Standards
Energy consumption by electric motors can be a significant portion of
a large industrial manufacturer’s operating budget. As a result NEMA
has created a new NEMA Premium Standard for Efficiency, providing users
with some guidelines
to use for selecting motors for efficiency and best payback for power consumption.
The Ultra line of motors meets and in several cases exceeds this standard.
-
Best-in-Class Drive Compatibility
Electric motors are being used in increasing percentages on variable frequency
drives. As a result, we have added several elements to our motor design to
allow customers to apply the Ultra motor in their applications with greater
flexibility. The insulation system has been designed to exceed the NEMA standard
MG1-31 regarding Inverter Duty Motor Insulation. Further, the Ultra motor has
a specially designed shaft on the opposite drive end (ODE) to allow for field
installation of a tachometer to provide process feedback to the drive.
-
A Product of ecomagination
For a product to have the ecomagination mark it must meet two
criteria:
- Measurably improve the customers environmental
performance and
- Significantly and measurably improve the
customers operating performance.
The X$D Ultra® motor achieves both. It meets or exceeds the NEMA Nominal
Premium Efficiency Standards and exceeds the minimum guarantee. Therefore improved
energy consumption and usage are dramatically realized. The X$D Ultra’s
low temperature rise and low vibration is perfect for harsh environments in
a variety of industries (Oil & Gas, Energy, Pulp & Paper, Chemical,
etc.). It is the ultimate Ultra motor for any application where the
operating conditions are less than perfect and uptime is a very high
priority.
-
Safety is an Important Feature
The entire X$D Ultra product range incorporates a 4 point cast-in-lifting
lug system. These lugs are an integral part of the frame of the X$D Ultra motor
allowing for safer lifting during installation and maintenance. This is a convenient
and safe feature when mounting the motor in vertical or horizontal positions.
