KEB COMBIVERT P6 Pitch Drive System

  • Compact unit with variable installation position due to fan axis in x, y or z direction
  • Additionally with integrated Soft SPS
  • Powerful IEC 61131 programming
  • Battery monitoring and loading for lead gel or ultracapacitor
  • Integrated 24 v DC supply and EMC filter
  • Flexible communication with operational design via RS 232, Modbus TCP
  • Optional fieldbus systems CANopen, Profibus and InterBus
  • Various sensor systems of motors 
  • Can be switched between synchronous, asynchronous and DC-motors

KEB PITCH Drive Trains

are specially developed for the operation in wind power plants and composed of optimized synchronous servo motors with an internal encoder system and IP 65 protected safety brakes. The brake motors meet the highest requirements for quality, dynamics and positioning accuracy together with low construction volume and weight and they move the rotor blades or the nacelles powerfully, efficiently and safely! Technical properties include

  • smooth surface without fan
  • parallel, rotatable power and encoder interfaces
  • protective system IP 65 for hardest environmental conditions
  • ideal for offshore-operation because of no possibility of leakage and a special offshore-coating is possible optionally
  • simple installation in different mounting positions
  • robust assembly with high vibration resistance
