GE HV Wound Rotor Induction Motors are engineered to meet the demanding requirements of industrial applications such as centrifugal compressors, blowers, boiler feed pumps, crushers and grinders, and multi-stage high pressure pumps.

The motors are designed in compliance with critical industry standards, including NEMA MG1, IEC 60034-1, ANSI C50.41, IEEE 112, API 541 & 547, and applicable ISO, AFBMA, ANSI, ASME, and ASTM requirements.

GE HV Wound Rotor Induction Motors are renowned for their superior design, meeting or exceeding API 541 requirements for Petroleum & Chemical Applications. The motors feature robust construction and are built to withstand harsh operating environments. They are also equipped with an advanced insulation system that meets the requirements of NEMA MG-1, part 31.

For industrial pump, fan, compressor

and other industrial applications.

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.
