Encoders for Wind Turbines from Fraba.

Encoders are used in wind turbines primarily to maximize efficiency, by enchanced positioning of various parts.

The speed of the rotor depends on the pitch of the blades as well as the direction of the wind. Hence a proper positioning of the blade is required for highest efficiency. An absolute rotary encoder on the base of each blade ensures this.

The rotor and the nacelle must be in the right direction as compared to the wind in order to ensure proper functioning. Absolute Rotary encoders are used to achieve this precise positioning

FRABA encoders are already being used in large quantities in wind turbines worldwide. For specific needs FRABA can offer Optical as well as Magnetic Absolute Rotary Encoders. These precise, cost efficient systems are well suited for the harsh weather conditions the wind turbine has to withstand, especially continuous lightning strikes.

About Fraba:

The FRABA Group, as one of the leading manufacturers of high technology sensor and safety systems for industrial automation, is committed to excellence in quality and customer service. The headquarters are located in Cologne, Germany. The first US subsidiary, FRABA Inc., began operations in summer 2000 in Lawrenceville, NJ to better meet the growing needs of the American encoder market.

With the POSITAL product range, FRABA strengthens their leadership in absolute encoders, which they have developed for over thirty years. The POSITAL encoders utilize optical technology and integrated intelligence and combine high performance, high quality, and low cost. The FRABA experts support the standard interfaces (serial and parallel), as well as the new fieldbus interfaces like DeviceNet, Profibus, and Interbus. From robotics to steel-mills and packing machines, a wide variety of applications are positioned by POSITAL encoders all around the world.
