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:
NEMA MG1
IEC 60034-1
ANSI C50.41
IEEE 112
API 541 & 547
Applicable ISO, AFBMA, ANSI, ASME, and ASTM requirements

Quality

Our world-class testing facility has the capability of meeting a wide range of NEMA,
IEC and API 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.

Superior Design

Meets or exceeds API 541
requirements for Petroleum
& Chemical Applications

GE provides machines that are fully compliant to API 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.

Inverter Duty

The insulation system meets the requirements of NEMA MG-1,

part 31. If required, a shaft grounding device is installed to

reduce shaft voltage. Both 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.

Reduction of Resonances

GE supplies both flexible and rigid rotor technology. All

machines 1800 rpm and below have rigid rotors as defined

by API. 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.

Stator frames are designed using powerful
FEA tools. The design tools confirm safety
margins, and assure resonances are well
outside the operating region.

Improved ventilation
and cooling has been
achieved with a new
internal fan design.

Built 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.

Insulation System

GE uses an epoxy solventless resin vacuum-pressure-im-

pregnation (VPI) process assuring long life. For line voltages

of 5000 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-1776. The coils receive a

protective armor of heavy glass tape for protection against

mechanical shock and abrasion. Custom Polyseal

winding insulation system that meets the requirements of

NEMA MG1 20.18..

It is available upon

request to operate in

severe environments

containing moisture,

oil, chemicals and

salt water.

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.

Bearings

GE uses self-aligning spherical seat sleeve bearings per DIN
31693/4. Seal additions are also available to meet IP-56
requirements. Anti-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.

Accurate 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 - Benefits

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 FEA modeling (including Torsional, Radial and Axial

loads) help ensure rotor designs meet specifed application

requirements.

Bearing Design

API compliant options are available for the rolling

element and sleeve bearing

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.

Brush 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. An optional solution from

GE, called a Brush Lifting Device, is an integrated mechanism,

which shorts the slip rings and lifts the brushes at nominal

speed to avoid this wear.
