Siemens Sinamics GL150 Variable Frequency Drive

SINAMICS GL150 is designed as a drive converter for single-motor applications with variable and constant torque characteristic. The converter is available in air- and water-cooled design and achieves power ratings up to 74 MW (water-cooled design). Higher ratings are available on request.

SINAMICS GL150 is used for speed-variable operation as well as for start-up operation of large synchronous motors and generators. The typical speed range extends up to approx. 6000 rpm. When used as start-up converter the speed-range is limited by the synchronous line frequency. Within this range a speed control range of 1:10 or 1:100 can be realized. Due to the topology regenerative (4 Q) operation is possible without additional measures. The drive converters SINAMICS GL150 offer an economical drive solution for highest power ratings of 74 MW and beyond, which can be adapted to specific customer needs with a wide range of optionally available components and accessories.
