X$DUltra® - NEMA Premium Extra Severe Duty Motors ? a product of ecomagination?
NEMA 143-449 Frame
1 1/2 to 400 HP AC Motors
GE Industrial Systems has introduced a new line of electric motors with improved performance characteristics for Industrial Users. Named Ultra ?, this product line was developed utilizing the GE six-sigma quality design for manufacturing techniques specifically to minimize overall lifecycle costs. Key customer needs addressed with this new design are compatibility with adjustable speed drives, improved insulation and bearing life, lower power consumption through increased efficiency, and product safety.
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 .04 IPS (inches per second), reducing a leading cause of bearing failure. Regreasing consideration has been made easy with extended greasing provisions, which allows motor users 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, giving users some guidelines to use for selecting motors for Efficiency and best payback for power consumption. The Ultra ? line of motors meets or 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 special designed shaft on the opposite drive end (ODE) to allow for field installation of a tachometer to provide process feedback to the drive.
