Wind energy

Optimized for certification, installation and efficient operation on everything from the rotor blades, gearbox and generator to the pitch and azimuth system:

Discover encoders and sensors from HEIDENHAIN and its brands AMO, LEINE LINDE and LTN, designed for the rigourous requirements of wind turbines.

Wind power is one of the main pillars in the transition from fossil fuels to renewable energy. Acheiving renewable energy goals requires more than a mere increase in the number of wind turbines. Their service life and performance must be optimized as well. Encoders, sensors and slip rings support this optimization throughout the manufacturing, operating and maintenance processes by delivering high-accuracy position, speed and load data for a wide range of wind-turbine components.

Optimal performance for wind turbines

In order to maximize the efficiency and service life of a wind turbine, the control system needs reliable, real-time data about vibrations and structural loads acting on the tower, bed plate and rotor blades. Collecting this information as it unfolds in real time makes it possible to integrate active load control strategies and monitoring functions into the control system.

The benefits are significant:

  • Longer service life
  • Less maintenance
  • Higher energy yields
  • Lower structural component costs

The components of this system are characterized by the following:

  • Unique combination of resolution and measuring range
  • Good signal-to-noise ratio
  • Simple installation and start-up
  • Stable measurements over long time periods
