The Moog EPA3 slip ring is well suited for both large and small wind turbines. Its high reliability and modular design can be scaled and optimized for most requirements. It utilizes Fiber On Tip (FOT) power contacting technology. No maintenance (cleaning) is required. The slip ring can be part of a large wind turbine electric pitch control system with the option to integrate hydraulic pitch control systems, if required. It can also be used on the yaw axis of small wind turbines. Speeds range from 0 to 100 rpm with through-bore model sizes up to 54mm available.
