Synchronous Rotors
~ Highest Available Efficiency
~ Brushless Excitation for Minimum
Maintenance and Maximum Reliability
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
2
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 rotor-
mounted 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.
Wound Rotors
~ Versatile
~ Long Track Record of Success
~ Soft Starts
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.
