Moog Introduces New Slip Ring

Moog Components Group has introduced 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 company says the advantage of this slip ring over traditional models is its performance and quality in harsh environments. Utilizing fiber brushes and robust mechanical components in the slip ring design, the company adds.

The AC7008 slip ring operates maintenance-free for over 100 million revolutions. The product's fiber brush technology is able to achieve long life without lubrication over a wide range of temperatures, humidity and rotational speeds, according to the company. In addition, the fiber brush has the capability to handle high power while, at the same time, transferring data signals.

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.
