In addition to the low voltage motors in special rail version our portfolio also includes highly efficient traction motors, main and auxiliary operating generators and their regulating systems. These are used among others in:

  • electric and diesel-electric locomotives
  • multiple unit trains
  • metros
  • trolley/ hybrid buses
  • trams and
  • vehicles for work
