Synchronous generators


Machine building is our passion – in particular, when it comes to special machines as synchronous generators. For the power range up to 20,000 kVA and voltages up to 15,000 V, we will develop and produce a generator tailored to your needs, repair it, and commission the machine. Our generators are based on a system series and are often characterised by a welded enclosure base model. With a range of additional components that can be varied in accordance with the modular concept, our generators meet all the demands placed on modern manufacturing systems in terms of equipment parameters, operating conditions and protection category.

Our range of services

  • Development of customised solutions
  • Production
  • Regular maintenance and inspection
  • Tests
  • Repair, incl. on-site service, from the diagnosis via removal of the equipment and disassembly to transport, return transport, and reassembly
  • On-site service for generators up to 250 MVA, irrespective of the brand/manufacturer
  • Commissioning

Your advantages at a glance

  • Tailored especially to your product
  • Functional embedding of machines also possible in systems with high degree of complexity
  • Maximum efficiency
  • Global vacuum pressure insulation (GVPI) technology
  • Technical support and comprehensive service during the whole generator service life
  • Low maintenance costs
  • Service-oriented design
  • Solid, reliable product made in Germany


We develop and produce synchronous generators for the most varied areas of application to fully meet your requirements. For example, we deliver hydroelectric generators up to 20 MVA in horizontal and vertical design and generators for steam turbines up to 18 MVA. Generators for power generation for the on-board power supply on ships and for stationary systems (onshore and offshore) up to 20 MVA are also part of our product portfolio.

Furthermore, we manufacture laminated cores from segmented laminations, and wind, impregnate, test and package them.
