Pitch Products for Wind Turbines

The motion control challenges for wind turbines are particularly complex, ranging from assuring efficiency to increasing reliability and safety. Moog offers high-performance electric and hydraulic pitch products and systems. In more than 26 countries worldwide, Moog teams work proactively with customers to take ideas further, incorporate higher performance, reduce operating costs and facilitate the development of next generation machine design.

Electric Pitch Products

Pitch Servo Drives

As part of our Pitch Systems, these products are developed to withstand the harsh conditions in the rotating hub and operate reliably under internal switchgear cabinet temperatures from -30 to +70° C (-22 to 158° F). Our flexible designs provide selectable installation positions and resistance to vibration, shock and permanent shock.

Pitch Motors

As part of our Pitch System, Moog’s new AC Pitch Motor has sensorless technology that is capable of driving the required torques and speeds needed for safe feathering even during the grid loss condition in pitch control applications. It has higher safety and higher servo motion performance in a smaller package with an integrated blade brake unit. DC motors are also available for pitch systems requiring this safety concept.

Hydraulic Pitch Products

Pitch Valves

Our valve features microprocessor based electronics and CANopen, Profibus DP or Real-Time Ethernet fieldbus interfaces. This enables fully digital communication for improved performance, enhanced remote diagnostics and greater process control.

Pitch Pumps

Moog delivers the Hydraulic Pitch Pump (RKP) as part of the Hydraulic Power Unit. The pump features low noise and provides longer service life. It is available with digital onboard electronics for remote maintenance and condition monitoring.

Remote Servicing for Pitch Systems

Remote Terminal Software

The Moog Wind Turbine Pitch Remote Terminal Software for pitch systems offers remote or on-site access and ensures that operators and manufacturers are able to perform operational analysis and monitoring based on real data.
