SINAMICS GL150

The rugged LCI variable speed and starting converter for large synchronous motors and generators up to 85 MW

sinamics gl150 12p 12p water cooled

The LCI-converter (load commutated inverter), SINAMICS GL150, is designed for single-motor applications with variable and constant torque characteristics in power ratings up to 85 MW (Higher ratings on request). Available in air- and water-cooled designs and capable of 2Q or 4Q operation. Commonly used for variable-speed operation as well as for start-up operation of large synchronous motors and generators and with speeds ranging up to approx. 7000 rpm.


New SINAMICS GL150 innovation design

The converter power section of the air-cooled SINAMICS GL150 has been upgraded to provide an optimized solution in the lower power range (6p/6p up to 5 MW; 12p/12p up to 9 MW).

The new innovative design is characterized by:

  • Economic and highly-efficient drive design

  • Compact dimensions

  • Arc fault- and earthquake tests proved design

  • Accessibility of the low-voltage section, even during operation

  • An special "line-side fuses" retrofit option integrated in the design


Your Benefits

  • Compact design and highest power density

  • Easy plant integration due to compact design and highly flexible configuration

  • Simple operator control with the user-friendly operator panel

  • High reliability and ruggedness through the use of extremely robust thyristor technology and fuseless design, combined with an intelligent response to external disturbances

  • Hassle-free integration into higher-level automation systems through analog and digital interfaces and PROFIBUS DP

  • Designed for synchronous motors in an almost maintenance-free design

Applications – by industry

industries oil gas siemens

Oil & Gas

Chemical & Petrochemical

Chemical & Petrochemical


Most commonly found in the Oil & Gas industry with applications that require a starting converter or where the power required is over 30 MW with large compressors or pumps, especially common in some LNG applications.

 Large compressors - above 30 MW Large pumps - above 30 MW

Primarily used in the Chemical & Petrochemical industry for the more complex applications with power requirements over 30 MW, such as really large pumps.
