Higher speed motors
(four and six poles) use a compact,
brushless exciter unit mounted on the rotor shaft outboard
of the bearings. No independent support or alignment is
required. The high level of field forcing delivers improved
system performance, which increases the production of
reactive power and is beneficial when faults arise in the
supply network.
Lower speed motors
(eight or more poles) typically have a
brushless exciter unit mounted inside the motor enclosure.
Excitation control
The motor excitation control panel can be supplied in a variety
of basic formats. It houses the excitation equipment, protection
system and logic functions for starting. Various options are
available on request.
We offer a wide range of instrumentation and control equipment
to protect synchronous motors and ensure excellent reliability
and availability, and extended product lifetimes.
Integration with plant automation systems
The motor excitation control panel can, as an option, be
adapted for immediate integration into a superior management
and supervisory system. Communication via modem can
also be supplied to facilitate remote support.
