Wind power is one of the main pillars in the transition from fossil fuels to renewable energy. Achieving 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.

Solutions for wind turbines

Wind turbines may look similar on the outside, but the way they generate power behind the walls of their nacelle varies.

Wind turbines equipped with a gearbox can leverage the many benefits of a high-speed generator. These generators are compact and rotate much faster than the rotor. The results are greater efficiency and an electrical frequency that matches the power grid.

Wind turbines without a gearbox are more compact and contain fewer moving parts. But these benefits are offset by an expensive ring generator requiring ever greater weight for higher performance. Even for these generators, we provide reliable and easy-to-install modular encoders with very large diameters.

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
