Benefits
Unique Bridge Design
Maximized Up-Time –
Reliability
Each bridge uses full voltage
rated devices in an easy to
maintain configuration.
The standard N+1 SCR
redundancy insures full power
output even in the event of a
device failure.
Highest System Efficiency
Synch motor and LCI
combination give highest
efficiency drive system available.
Most Cost Effective High
HP Systems
High efficiency means reduced
energy costs for total project life.
Input Configuration
Power System Friendly
Drive can be configured for
6-, 12- or 24-pulse input.
Flexibility allows most cost
efficient installations. LCI can
be used as motor control or for
motor starting applications.
Water Cooled Technology
Compact Quiet Design
Fully redundant system, hoses
don’t need to be disconnected
for bridge service.
Reduces maintenance and
ambient noise, saves your
valuable floor space, allows
for transformer to be remotely
mounted (outdoors).
Windows®-Based
Configuration and
Maintenance Tools
Faster Commissioning
and Maintenance
For pc-based configuration, the
Control System Toolbox features:
• Animated block diagrams
• Integrated trend window
The LCI drive is ideal for any high power
synchronous motor application for which adjustable
speed operation or soft starting is needed.
Adjustable speed operation allows optimal efficiency
(energy saving) and improved process accuracy. Typical
adjustable speed applications include:
• Compressors for air or petrochemical processes
• ID fans for coal-fired boilers
• Grinding mills
• Rod and bar mills
• Marine Propulsion
These world-class tools
drive productivity in
commissioning and typical
maintenance activities.

Soft-starting reduces the mechanical stress on the motor and driven equipment as well as eliminating electrical starting
surges on the ac power system. The rating of the starting system depends on the power required to drive the load
at synchronous speed. However, because many driven machines can be arranged for reduced load operation during
starting, power rating of the starting equipment can be greatly reduced. An output transformer permits the LCI drive to
operate with any motor voltage. The LCI drive has a closed transition for synchronizing/de-synchronizing function that
means no other synchronizing equipment is needed to smoothly start multiple large motors.
Bringing Powerful Control
To A Wide Variety Of Industries
The LCI drive’s robust power bridge design and long years of proven
operational reliability make it the ideal solution for your high horsepower
compressor applications. One applications uses LCIs and electric motors
to replace gas turbine drives to eliminate emissions, reduce noise, reduce
maintenance and increase operational efficiency and control.
Compressor Station
The LCI drive can be seamlessly integrated with the rest of your
pump or compressor station control system. Supporting a variety
of Local Area Networks (LAN) and hardwired I/O allows you the
flexibility necessary for remote and even un-manned operations.
Pump Station
The LCI has been used to power many types of grinding mill
applications. It can be used to start multiple mills or function as a
dedicated power supply to a mill for optimal process control and
variability.
Grinding Mill
Traditional mechanical methods for controlling airflow are
inefficient and require considerable maintenance. The LCI
provides more accurate and energy efficient control of airflow
while eliminating the maintenance associated with dampers or
vanes. Any large fan application, like a cement or utility ID fans,
will benefit from using the LCI for controlling its synchronous
motor.
Induced Draft (ID) Fan
In the configuration, start-up, and maintenance of large drive
systems like ship propulsion, a PC-based programming tool
is essential. The LCI utilizes many parts of the TMEIC Control
System Toolbox software package. This package is shared
across a number of drive platforms and results in reduced
customer training time.

Control System Toolbox – A Common
Tool Across all TMEIC Drive Products
Drive Commissioning with an Integrated Trend Window
For knowledge management inside the LCI, the Control System Toolbox provides animated graphic displays of control
logic as well as an integrated window for the trending of drive and related process variables. This tool features ease of
configuration and data analysis.
Trend Configuration
• Define a trend with drag and drop of variables from
function block diagrams or select variables from a
pick list
• Conduct online real-time trending with the drive or
upload the capture buffers in the drive for trending.
For historical trending, define a link with an integrated
historian database.

Load Commutated Inverter (LCI) Theory
The LCI operation is simple and reliable. It uses
load-commutated, phase-controlled power thyristor
technology to supply power to the stator windings of a
high efficiency synchronous motor.
Synchronous
Motor
3
SCR
Converters
Isolation
Transformer
The power circuit has a source converter, connected to
the power supply and a load converter connected to the
motor. When motoring, power flows from the power
source to the motor. Regeneration is built in, allowing
smooth control of loads in all operations.
The LCI controls the motor torque to regulate motor
speed. Motor torque is controlled through the DC link
current.
The LCI power converter blocks can be paralleled to
deliver ratings in excess of 70,000 HP. Multi-channel
output gives low harmonics on the motor and gives the
opportunity for single channel operation. Consult TMEIC
General Industries for custom systems to meet your
requirements.
