Moog Components Group has announced the introduction of a new slip ring that is a direct replacement for pitch control slip rings on the GE 1.5 MW series wind turbines.
The AC7008 slip ring provides reliable transmission of power and data signals from the nacelle to the control system for the rotary blades. The advantage of this slip ring over traditional models is its performance and quality in harsh environments. Costly downtime is eliminated by utilizing fiber brushes and robust mechanical components in the slip ring design.
The AC7008 slip ring operates maintenance free for over 100 million revolutions. A
unique feature of the fiber brush technology is its ability to achieve long life without lubrication over a wide range of temperatures, humidity and rotational speeds. In addition, the fiber brush has the capability to handle high power while at the same time transferring data signals.
Moog has long recognized the value of fiber brushes for long life, space efficient slip rings. Moog’s patented approach has led to hundreds of different slip ring designs for a variety of challenging applications — from satellite solar array drive power transfer to industrial packaging equipment.
Key Advantages of the Slip Ring:
-Maintenance free for over 100 million revolutions
-Minimal wear debris generation
-No lubrication required
-Wide operating temperatures
-Lower life cycle cost
-High reliability
The Moog AC7008 slip ring provides direct connection to the gearbox with wire terminal connections in both the stator and rotor junction boxes. Each unit is shipped with a heater installed. The slip ring is protected from the environment and sealed to an IP54 rating.
