Our products for wind energy
Limit switch for Yaw drives
In the field of azimuth adjustment rotary limit switches play a major role. They are usually connected via a measuring pinion either directly to the Yaw gear rim or to the drive pinion of a Yaw motor. They fulfil 2 safety relevant functions:
- Cable twist switch
The movement of the nacelle is limited to a certain number of revolutions, so that the cables hanging in the tower are protected from twisting and thus from being torn off.
- Position detection / wind tracking
By integrating electronic components such as potentiometers, incremental encoders or absolute value encoders, the exact nacelle position can be recorded and monitored.
Limit switch for pitch drives
By changing the blade angle of the wind turbine, the speed of rotation and thus the generated power can be significantly influenced.
The rotary limit switches are mainly used to generate an exact position signal of the blade position. The basis for an exact adjustment of the blade angle is the possibility to determine the momentary position with high accuracy.
Our measuring pinions are specially manufactured for use with encoders and rotary limit switches. They are sold in conjunction with our rotary limit switches of the FRS, FCN and FRM series, but can also be adapted to any shaft size of absolute or incremental encoders.
The largest area of application for these products is wind power, where especially the rotation of the blades or nacelle is monitored by means of these gears together with rotary limit switches.
The B-COMMAND team has a long tradition and many years of experience in the wind energy industry.
The company, based in Hamburg, Germany, focuses primarily on the production of rotary limit switches for wind turbines. In addition to our engineers, responsible for the 100% quality of our products, our international sales team is able to help you immediately with all commercial or technical questions.
