DC Motors with protection class IP21 – IP23 have a fully-laminated magnetic circuit. They are characterized by high power density and dynamic performance while highly short-term overloadable. Motors are available for  temperature class H, utilization class F and DIN EN 60034-01.

Special characteristics:

  • Wide adjusting  range at  high control accuracy
  • High power density with compact, space-saving type of construction
  • Flexible mounting possibilities
  • Well proven accessories program
  • Low noise values

Main applications:

Drive systems, mining, printing and paper industry, extruders, cranes, test fields, shipbuilding, steel works, rolling mills, wind tunnels, cement industry, converters and helper drivers for railways.
