Electric machines

In cooperation with LDW (Lloyd Dynamowerke in Germany) we offer bigger electric machines meeting all demands for reliability and efficiency. Motors designed and constructed by LDW matches the current application optimally.

The delivery program includes:

DC Motors

  • Shaft height: 112 to 1.000 mm in quadratic design, bigger sizes in round design
  • Efficiencies: 10 to approximately 8.000 kW
  • Torque: 20 to approximately 900.000 Nm
  • All common construction types and cooling methods, horizontal and vertical installation

AC Motors

  • AC Motors for high voltage and constant speed: up to 15 kV and 25 MW
  • AC Motors for variable speed through converter: up to 50 MW
  • All common construction types, cooling methods and protection classes
  • Executions for Ex-zone 1 and Ex-zone 2 are available with explosion protection: Ex “px” / Ex “pz” and increased security Ex “e” and Ex “nA” in accordance with ATEX guideline 94/9/EG and EN 60079 FF.

AC Compact Motors
