Series WKA | Stromag

For pitch drives, the mechanical switching contacts and high precision absolute encoders designed for single or multi turn operations are integrated in a housing. Besides the safeguarded cutoff in the final positions, the absolute position of the rotors in the wind are fedback to the control systems by 1:1 encoders. Pretensioned drive gears, also in conjunction with wheel adjustments, help to ensure rotary movements free from backlash from the slewing ball ring to the rotary encoder's input shaft. Also at the pitch switch, customised plug-in solutions can on request ensure time saving, simple installations free of potential confusion.
