Freudenberg designs new radial shaft seal ring for main bearings in wind turbines

The global expansion of wind-power facilities is proceeding unabated. Based on figures from Global Wind Energy Council, nearly 487 GW of output from wind energy were in place at the end of 2016. At the start of the decade, the installed output wasn’t even half that amount. It is not just the number of facilities that

Slip rings: A few ideas for extending their life

Jesse Shearer | Design Engineer | United Equipment Accessories As the wind energy industry has grown over the last decade, so has turbine slip ring technology. Although these devices are small, their importance should not be undervalued. Wind turbines require reliable transmission of power and data signals from the nacelle to the control system for

Turbine components: slip rings

What tests should a slip ring pass to consider it reliable? The most critical time to perform reliability tests on slip-ring assemblies is before they leave the factory. This is especially true when it is not feasible to perform a complete testing procedure on a product once installed up-tower. Analysis should consist of at least

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
