A new rotary electric contact method could radically change the way wind turbines generate electricity

Posted by in category: sustainability

Sandia National Laboratories researchers have developed a fundamentally new type of rotary electrical contact. The technology is called Twistact, and it will eliminate the need for expensive rare-earth magnets in large wind turbines.

Sandia is now ready to partner with the energy industry to develop the next generation of direct-drive wind turbines.

Sandia’s Twistact is a novel approach to transmitting electrical current between a stationary and rotating frame, or between two rotating assemblies having different speeds or rotational directions. This method is ideal for use in wind turbines.
