2 Experience Matters For over 100 years, GE has produced countless medium voltage induction machines for the petrochemical, power generation, mining and minerals, water and wastewater industries. These motors are commonly used for centrifugal compressors, blowers, boiler feed pumps, crushers and grinders, multi-stage high pressure pumps such as water injection or pipeline applications. Standards GE motors are designed for, but are not limited to these critical industry standards: NEM MG1 IEC NSI C50.41 IEEE 112 PI 541 & 547 pplicable ISO, FM, NSI, SME, and STM requirements Quality Our world-class testing facility has the capability of meeting a wide range of NEM, IEC and PI motor requirements. GE is dedicated to manufacturing excellence. Our facilities are ISO 9001 Certified with over 20 years of Six Sigma process enhancements and best practice implementations. Our commitment is to deliver the highest quality design to fit your system requirements with service to exceed your expectations.

3 Superior Design Meets or exceeds PI 541 requirements for Petroleum & Chemical pplications GE provides machines that are fully compliant to PI 541 standards, globally recognized among the most stringent. You can be assured that you are getting a well-designed and reliable product, optimized for your specific application. Reduction of Resonances GE supplies both flexible and rigid rotor technology. ll machines 1800 rpm and below have rigid rotors as defined by PI. Use of the latest engineering simulation tools and modern modal testing equipment makes it possible for GE to assure shaft resonances do not impede operation of the machine in the specified speed range. Inverter Duty The insulation system meets the requirements of NEM MG-1, part 31. If required, a shaft grounding device is installed to reduce shaft voltage. oth bearings are insulated and the drive end bearing is grounded. Our cage induction motors are certified for use with the GE MV4, MV6 and MV7000 range of variable frequency drives. Improved ventilation and cooling has been achieved with a new internal fan design. Stator frames are designed using powerful FE tools. The design tools confirm safety margins, and assure resonances are well outside the operating region.

4 uilt for Durability Stator Construction Laminations are precision punched from high quality, low loss electrical sheet steel with a temperature stable insulating film. The magnetic core consists of ring laminations compressed and completely wound before the core package is inserted into the frame. The stator assembly is configured for increased air flow which improves heat transfer and provides a more compact design. Rotor Construction The magnetic circuit consists of punched thin steel disks assembled to form a laminated core mounted on the shaft. The laminations are coated with a temperature stable insulating film to reduce magnetic losses yet maintain dimensional stability in the face of severe thermal and mechanical stresses. The rotor winding consists of a number of uninsulated metal bars in the outer surface of the magnetic core parallel to the shaft and short circuited by metal rings at both ends. Copper bars are brazed to their endrings, and aluminum bars are welded to their endrings. Insulation System GE uses an epoxy solventless resin vacuum-pressure-impregnation (VPI) process assuring long life. For line voltages of 0 Volts and above, a semi-conducting armor is applied to the slot portion and beyond the core to provide corona protection. The binding agent is GE s third generation epoxy resin, selected and tested to IEEE The coils receive a protective armor of heavy glass tape for protection against mechanical shock and abrasion. Custom Polyseal is a sealed winding insulation system that meets the requirements of NEM MG Ground Wall It is available upon Insulation request to operate in Turn severe environments Insulation containing moisture, Strand oil, chemicals and Insulation salt water. Copper Conductor earings GE uses self-aligning spherical seat sleeve bearings per DIN 31693/4. Seal additions are also available to meet IP-56 requirements. nti-friction bearings are available with grease in a sealed housing to avoid contamination meeting IP56 protection. Self-aligning spherical seat sleeve bearings have features designed to keep the oil in and the dirt out.

5 Vertical ccurate Frequency Response Design System resonance can shorten the life of your equipment. GE invested in the development and calibration of a new Reed Critical Frequency (RCF) prediction tool. It arms our engineers with the accurate data they need to create custom designs for specific application challenges. Frame Design - enefits Large inspection windows on both ends of the frame ensure easy maintenance and inspection access. The modular frame design accommodates multiple cooling, bearing loading and protection options without changing the motor stator frame. Rotor Design Shaft FE modeling (including Torsional, Radial and xial loads) help ensure rotor designs meet specifed application requirements. Wound Rotor Energy Recovery System GE wound rotor induction motors are designed to operate with Slip Energy Recovery drives within a standard range of 80% to 110% of the rated speed. Every design is optimized to suit each application and to provide maximum energy savings, effective speed control, and high reliability. Rotor Construction The rotor has a three-phase insulated winding. Rotor winding terminals are brought out through rotating slip rings and stationery brushes. These terminals are used to connect an external resistor in series with the rotor winding in order to control the motor accelerating torque and associated current. earing Design PI compliant options are available for the rolling element and sleeve bearing Stator earing Upper Endshield Chamber (Enclosed or Open Types) rush Lifting Device In a traditional application as the motor achieves nominal speed, the starting resistor is shorted out through the brushes between the slip rings. This shortens the life of the brushes and adds extra wear in the motor. n optional solution from GE, called a rush Lifting Device, is an integrated mechanism, which shorts the slip rings and lifts the brushes at nominal speed to avoid this wear.
