Stator Frame
and Magnetic Core

~ Low Loss Core Design
~ Easy Access for Routine

Maintenance

~ Low Vibration – Long Life

Our stator frame has been optimized
utilizing advanced finite element
analysis tools. Over the decades, these
structures have been proven to comply
with the most demanding industry
standards and requirements.

The stator core is made up of low
loss, high grade electrical sheet steel
insulated with an inorganic coating. By
combining high performance materials,
well-proven design techniques and
modern manufacturing tools, we are
able to offer some of the most compact
and efficient designs in the industry.

Insulation System

Ground Wall
Insulation

The reliability of our insulation systems
are validated through a combination
of rigorous qualification testing and
service life experience.

Our insulation system ensures long life
and reliability by meeting the stringent
mechanical and thermal requirements
of a wide range of challenging
specifications.

Our system is comprised of specially
engineered materials selected for
thermal capability, high dielectric
strength, electrical reliability and
chemical resistance. The system
then undergoes a Vacuum Pressure
Impregnation (VPI) process for added
protection and rigidity.

Acceptance Testing

Tests are made during the
manufacture of the windings to
assure that each machine meets
critical material and manufacturing
quality standards. Additional tests are
available to assure the machines meet
unique functional, environmental or
even regional requirements for every
application.

Rotors to Fit Your Applications

Cage Induction Rotors

~ High Performance
~ Rugged Reliability
~ Small Footprint

This well proven industry work horse
is available in a number of different
designs from low voltage fractional
horse power up to 300 ton machines.
Designs are offered with copper or
copper alloy, or for smaller machines,
both copper and fabricated aluminum.
Each machine is optimized to suit
specific needs by modifying the stator
and stator winding as well as the rotor
cage bar profiles and materials. In this
way a design can be optimized to give
the right starting torque capability,
ensuring high efficiency and an
optimized power factor.

With our ability to optimize motor
designs for use with variable frequency
drives, cage motors are now being
supplied for applications never
previously considered. GE has supplied
very high speed cage induction motors
that eliminate the need for gearboxes
(some of which operate at 20,000 rpm!)
Our mine hoist technology supplies
shaft-less induction motors in excess of
100 tons.

Aluminum Cage Construction

> Low mass bars and end-rings reduce
centrifugal force.

Copper Cage Construction

> This design provides greater capability
for starting high inertia loads.
> High efficiency helping to reduce
CO

emissions.

Synchronous Rotors

~ Highest Available Efficiency
~ Brushless Excitation for Minimum

Maintenance and Maximum Reliability

Wound Rotors

~ Versatile
~ Long Track Record of Success
~ Soft Starts

Synchronous motors are utilized for a
number of applications across a broad
range of industries. Because of the
high efficiency and controllable power
factor of the design, utility costs (and
CO

emissions) are minimal. Starting

characteristics and normal operating
performance can be optimized
separately and independently giving
you the benefits of both. A number of
different design options are available for
your application. Included are laminated
and solid pole designs – both cylindrical
and salient pole. GE also offers a unique
forged integral pole tip design well
suited to high load inertia applications.
Field windings are optimized to suit
individual applications utilizing either
wire wound or strip wound options.
By eliminating the need for a rotor­mounted synchronizing module, GE has
further improved motor reliability. Fixed
speed applications
benefit from the use of our ESP1
excitation control. This not only gives
reliable starting but also ensures the
best protection for your investment.

With the ability to provide a ‘soft-start’
when used in conjunction with a liquid
resistor as well as some speed control,
the wound rotor motor has long been
utilized in mining and other process
industries with great success.

By employing modern design
techniques and updated materials,
we have revitalized this technology.
Through our variable speed drive
expertise, we are now able to offer slip
energy recovery systems making this
an efficient option.

Bearings and Lubrication

Plain white metal or rolling element endshield-mounted
bearings are available appropriate to the motor speed
and application. All bearings are of the highest quality
produced to the standards of internationally recognized
manufacturers. This ensures replacement bearings will be
readily available.

GE I Power Conversion

Endshield & Pedestal
Sleeve Bearings

These bearing designs incorporate
specially developed multiple labyrinth
floating oil and air-seals. This ensures
dynamic pressure changes inside
the motor will not adversely affect
the lubrication system and allow for
IP56 degree protection. Center flange
bearings are used on larger machines
improving rotor dynamic performance
and overall efficiency. Self-contained
or flood lubricated options are
available along with suitable provisions
for emergency run-down.

Rolling Element /
Anti-Friction Bearings

Ball or roller type bearings on horizontal
machines are regreaseable and operate
smoothly providing long life with low
running noise. They are assembled with
grease in a sealed housing to avoid
contamination and allow for IP56 degree
protection. The lubrication system includes
a suitable pressure relief plug to purge
excess or old grease during lubrication.

Thrust Bearings

Angular contact ball, spherical roller and
sleeve tilting pad (hydrodynamic plate)
thrust bearings are designed to meet
specific project requirements. Depending
upon application, bearings can be self­contained grease or oil lubricated, water
cooled or flood lubricated.

Vibration

All motors are capable of complying
with the requirements of API 541, 547
or 546 (as applicable). The rotors are
dynamically balanced in two or more
planes. The vibration level is then
checked in the factory before and
after over-speed tests. This check is
designed to prove the stability required
to achieve quiet operation and long
bearing life.
