LCI Brochure TMEIC logo.indd 1 1/30/2012 11:17:13 AM

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

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.

LCI Features Benefits

Unique Bridge DesignEach bridge uses full voltage rated devices in an easy to maintain configuration.

Maximized Up-Time – ReliabilityThe standard N+1 SCR redundancy insures full power output even in the event of a device failure.

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.

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.

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.

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.

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.

• 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.

• Quickly define a display with the auto-scaling toolbar button

• Analyze a specific time frame with the zoom in/out toolbar buttons

• Create different views using variable hiding• Analyze specific times with a crosshair• Perform frequency-based analysis of the trend using

the fast fourier transform (FFT) function

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.

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.
