Yaw drive systems

The future of Yaw control

Low wind turbine costs and LCoE

Conventional concepts with motors running directly on the grid involve certain technological drawbacks. Unwanted loads due to abrupt start-up operations increase mechanical wear and tear. In addition, the electrical and hydraulic systems need to harmonize.

These problems can be addressed through the use of a controlled multi-axis drive system that synchronizes and optimizes the drive output power of the individual motors. KEBA’s modular KeDrive D3 system supports this approach using state-of-the-art servo drive technology.

Your benefits at a glance

Higher energy yield thanks to more accurate yawing
Significantly less wear of mechanical components thanks to the active clamping of the axes
Controlled acceleration and braking torque for 4-quadrant operation
Lower wind turbine costs thanks to the replacement of slow hydraulic brakes

High power range and active energy recovery

The product service life of a wind turbine installation is 25 years and longer and requires low-wearing intelligent control concepts for the multi-axis group. KEBA, the servo specialist, offers you a wide range of experience and references in the dynamic synchronization of multi-axis solutions including the compensation of gear faults.
