The Blade Pitch System

One special technical feature of VENSYS wind turbines is the lubrication-free and low-maintenance toothed belt which transmits the force between the pitch drive and the rotor blade. Our drive system minimizes wear and increases safety.
The drive of the blade is equipped with an energy storage device (capacitor) which makes it possible to drive the blades into braking position in the event of a grid blackout. The capacitors can deliver the necessary power even in low temperatures. An additional asset is their long service life.

Our innovative toothed belt drive for the blade pitch system has stood the test of time: for more than 20 years now. In more than 11,700 wind turbines around the world – and under the most different regional conditions: in strong wind areas just as much as on inland sites with increased hub height.
