Hübner Giessen develops pitch servo drives for large wind turbines – contract confirmed

The Hübner Giessen Pitch Servo Drive was specially developed as a direct current solution to guarantee through battery backup that it remains possible in the event of an emergency (for example lightning strike) to adjust the pitch of the rotor blades without inverter electronics. This is a huge advantage in comparison with conventional three-phase powered pitch servo drives. Particularly distinguishing features of the Pitch Servo Drive G 21 are the compact design and very good operating properties, meaning commutation and control characteristics.
