High speed servo drive system
The SFAK series of liquid resistance starters covers a power range from 1,500 to 20,000 kW of engine output. They are usually used as liquid resistance starters for metal shredding drive systems due to their highly dynamic control and positioning characteristics. The smooth, spindleless and wear-resistant electrode adjustment enables a high level of positioning accuracy. Due to their wide dynamic range and control precision they are also employed in turbine and compressor test rigs, steel works, in Ilgner converters, or to start and
synchronise the water pumps in hydroelectric energy storage.
The SFAK series is also offered with a slip ring motor, medium voltage switch gear and re-cooling system as part of a complete solution. It goes without saying that the latest motor management system and PLC control via a Profibus or Ethernet interface are included.
