Severe duty motors deliver operational performance, lower GHG emissions
Operators of industrial applications in the power generation, oil and gas, mining, chemical, steel and other heavy industries now have a new option for operational power and environmental performance from GE Energy’s new X$D Ultra 841 IEC extra severe duty motors.
The X$D Ultra 841 IEC is designed to meet or exceed the requirements of the IEEE 841-2009 Standard and is designed and rated for Zone 2 and Division 2 hazardous applications with a T3 (200°C) or lower temperature code. It is also designed to meet or exceed IE3 and NEMA Premium nominal efficiencies and reportedly exceeds all IEC and NEMA Premium minimum guaranteed efficiencies. Each X$D Ultra 841 motor also comes with its own test report demonstrating performance during testing compliant with the IEEE 841-2009 specifications and all metric IEC construction and design requirements.
“With an advanced insulation and bearing system, IE3 efficiencies, a test report of each motor to ensure performance, five-year warranty and all the advanced features that come with it, the GE X$D Ultra 841 IEC is the most durable and reliable low voltage motor our customers can buy,” says Tim Marker, product line manager for Low Voltage Motors.
Proven, Reliable Energy Saver
According to Marker, if a U.S. industrial user replaced one 75KW 1800 RPM Pre-EPAct/Eff3 motor with an X$D Ultra 841 IEC, in one year it could save enough energy to fully power at least two households over the same period, and, greenhouse gas emissions could be reduced by as much as 5.7 metric tons per year.
With a rugged cast iron frame, conduit box, endshields, and fan cover, the XSD Ultra 841 IEC class H inverter duty insulation system allegedly continued to operate after being subjected to 1,000,000 plug reversals during an internal test. Backed with a standard five-year warranty (60 months operational/66 months maximum from shipment), the motor features cast-in vibration pads (five radial and at least three axial) to help provide for easy and repeatable vibration measurements. Additionally, the Draft Angle on top of all mounting feet is 1.50 degrees or less to help ensure secure mounting.
Along with delivering enhanced operational and environmental performance, GE’s X$D Ultra 841 IEC Extra Severe Duty Motors offer:
- GE’s Six Star Bearing System helps maximize bearing life when combined with a maintenance program;
- GEGARD2400 insulation system exceeds both the IEEE 841-2009 and NEMA MG1-31 specifications and the requirements of the IEC 60034-17 and 60034-18-41 standards;
- Easy serviceability via oversized gasketed conduit box, containing permanently labeled non-wicking Class H leads to a terminal board;
- Severe duty corrosion protection – featuring an epoxy ester paint system – meets IEEE 841-2009 specification paint requirements while the motor frame, fan cover, endshield and conduit box are cast iron;
- Safety features including a four-point lifting system versus a single eyebolt; cast-in lifting lugs; grease inlet fitting at 12 o’clock and outlet fitting at 4 o’clock or 8 o’clock position; silicon bronze box lug and frame earthing terminals.
