Solution portfolio for your turbine platform

In order to achieve the optimal design of a wind turbine installation, a wide array of legal requirements, standards, and practices must be combined.
A large portion of these relate to the pitch system and the yaw drive system.
KEBA provides advice for the design of your pitch and yaw motors as well as the associated drive controllers, based on your load specifications.
The latest developments in power provision and comprehensive TÜV-certified safety features for simulation-based testing help our customers in the validation process and thus ensure an effective life cycle management of the wind turbines.

Subsequently, this can also be used for slimming down the structural components from the blade tip to the foundation. This opens up great savings potential.
Whether you need troubleshooting support during commissioning or during normal operation of the plant, you can always draw on the know-how of our experts.
For repairs, spare parts or retrofitting operations, our skilled personnel provide competent advice and best-in-class support.

Yaw drive

The demand for lower wind turbine costs and LCoE extends to yaw drive applications, too. 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.

Ease of maintenance

Reduced number of components

The Pitch drives include a PWM voltage brake driver for the direct actuation of the motor brake. Like the built-in backup power charger, this further reduces the number of components in the cabinet and maximizes availability and ease of maintenance.

High availability

Suitable for elevations up to 3,000 meters

Electric Pitch systems and Yaw drive systems are suitable for installation at elevations up to 3,000 m and internal cabinet temperatures between -40 to +70 °C.
The innovative product features of this

device platform include intelligent DC link precharging, which protects the slip ring from excessive charging currents and allows for optimized, safe fault-ride-through operation (LVRT, HVRT).
