Acquisition of nacelle position on azimuth bearing

The exact tracking by the nacelle of changing wind directions is a crucial factor for optimal energy yield. The central element here is the toothed azimuth bearing that connects the nacelle to the tower. It is therefore ideally suited for precise position acquisition of the nacelle.

Lenord + Bauer has developed a measuring system especially for this application; in addition to an absolute rotary encoder, this system comprises a bracket, flexible flange, target wheel and cable set.

Advantages of the absolute rotary encoders from Lenord + Bauer:

• High external axle loads are possible due to optimised bearings
• Robust magnetic sensors
• High resolution (max. 16 bits single turn, 28 bit multiturn)
• Suited for offshore operation, as well as applications in cold and hot climates
• Optionally available with digital interface SSI, CANopen, or PROFIBUS DP,
  or analogue interface 0 to 10 V or 4 to 20 mA
• Maintenance-free over the long term in single turn and gear multiturn operation
• Optionally available as IP 67 or IP 69 K variant
