New high reliability slip ring brings new technology to wind turbines
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.
Trends in slip rings
Slip rings provide a reliable transmission of power or signals from stationary cables in the nacelle to rotating equipment in the hub. A basic slip-ring assembly uses solid metal rings and graphite or precious-metal wire brushes, which contact the outside diameter of the rotating metal ring. As the ring turns, electrical current or signal conducts through…
How perfect (blade) pitch lightens wind turbine structural loads

An American pitch system in a Chinese turbine
U.S. manufacturer Moog has supplied an AC servo motion-controlled pitch system for a 3-MW wind turbine in China. “In 2011, China’s emphasis on wind energy development will boost the wind energy sector. Chinese wind turbine manufacturers are ramping up their investment to seize a larger share of the world market,” says Lars Rasmussen, Moog’s general manager for the Asia Pacific region.
A motor just for pitch
Pitch motors have a tough job. They spin around in a turbine hub and must work when it’s hot and cold. They are often on six-month maintenance intervals usually to check their brushes. It’s no wonder they konk-out after a few years. Engineers at Moog have recognized the problem and so devised a line of…
