Power Conversion
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.
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.
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.
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.
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.
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.
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.
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
®
is a sealed
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.
The stator assembly
is configured for
increased air flow
which improves
heat transfer and
provides a more
compact design.
Self-aligning spherical seat sleeve bearings have features designed
to keep the oil in and the dirt out.
Copper bars are brazed
to their endrings, and
aluminum bars are
welded to their endrings.

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
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.
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.
