The Moog Pitch Servo Drive, a component of Moog’s Pitch System responsible for guaranteeing the safe operation of wind turbines, obtained a TÜV certification for compliance with the guideline issued by Germanischer Lloyd. This validates that Moog designs achieve Performance Level D for the wind turbine feathering safety function. The safety of wind turbines is…

In this 40 minute webinar, learn how two common hazards can hamper a wind turbine’s production. Wind-turbine owners and operators may experience a significant reduction of generated power, reducing overall turbine efficiency, if they don’t take into account: Blade Icing Failed Slip Rings Issues Increased Reliability In this free webinar, we explore how Moog Blade…

A state-of-the art servodrive for electric pitch systems was on display at WINDPOWER 2010 in the Moog booth. The PITCHmaster II was developed for the harsh conditions prevailing in rotor hubs. It operates reliably at constant internal switch gear cabinet temperatures ranging from -22°F to 158°F. The design features several advantages, such as a capability…

In addition to hydraulically controlled and actuated blade pitch control systems, Parker can provide components and systems for dynamic performances with electromechanical technology. Parker’s electromechanical solutions, on display in Booth 10443, include dc drives with rugged designs and flexible connectivity, brushless servomotors in a full power range with flexible connection options, multi-axis motion controllers providing…

To provide smooth and consistent power outputs, wind-turbine manufacturers use hydraulics to set the “pitch” of the rotor blade. The Eaton Vickers KB range of proportional flow control valves from Eaton’s Hydraulics Operations, Eden Prairie, Minn., has been the frequently selected valve to control blade pitch. It is globally installed in over 20,000 turbines. KB…
