Fact Sheet
GE sets the standard...
Superior Performance
The X$D IEC meets or exceeds IE2 Nominal
efficiencies.
• Overall vibration is 1.6 mm/sec. (0.063 in. per second). This
helps to extend the life of the motor and the connected
equipment.
• Total shaft runout is 0.025 mm (0.001 in.) for shaft diameters
u
p to 41 mm and 0.038 mm (0.0015 in.) for shaft diameters
greater than 41 mm for ball bearing machines.
• GEGARD2400™ insulation systems features Class H
insulation
materials. This system increases motor protection
against IGBT
drive voltage spikes that typically can reach
2,400 volts @ 0.1 microsecond rise time, which exceeds
NEMA MG1-31 standards.
Bearings
GE’s Bearing System assures the maximum possible bearing
life when combined with a maintenance program. For optimum
performance, the same over-sized bearing is used on both
ends of the motor.
•
A steel-reinforced recessed slinger is integrated to both the
drive-end and opposite drive-end ensuring IP55 protection
.
• Fully charged lubrication system with a temperature-resistant
polyurea grease suitable for a wide temperature range
(-40°C
to +130°C).
• An oversized single-shielded bearing is open towards the
grease cavity for maximum lubricant circulation.
• 130,000 hours minimum bearing life for direct-drive loads,
and 26,280 hours for L10 belt-driven loads.
• A gasketed cast-iron inner bearing cap retains lubricant and
protects the bearing system and interior of the motor from
contaminants.
• Finned endshield for improved heat dissipation and long
bearing life (200-280 frame)
Proven Reliability
For years severe duty motors from GE have proven their
performance and reliability in the most demanding process
industry environments.
• A one-year warranty comes standard with every X$D IEC
motor. (12 months operational/18 months maximum from
s
hipment.)
• Cast-in vibration pads provide five-point vibration probe
mounting (four radial, one axial).
•
Rugged cast iron frame, conduit box, endshields, and fan cover.
Inverter Duty Application
The GEGARD2400™ insulation system exceeds
the NEMA MG1-31 specifications
and the
requirements of the
IEC 60034-17
and
60034-18-41
standards. It has the ability to withstand repeated 0.1 microsecond
rise time that typically can reach 2400 volt spikes for up to 575
line voltages.
• Infinite:1 variable torque speed range and 10:1 constant
torque* speed range available on request.
* Some exceptions apply to constant torque speed ranges. Contact
GE Energy to verify capability on specific ratings.
• All motors are tested to verify the Corona Inception Voltage
(CIV) at the factory before shipment.
