Sandia innovation eliminates reliance on rare-earth magnets for large-scale wind turbines

Green Car Congress

Motivated by the need to eliminate expensive rare-earth magnets in utility-scale direct-drive wind turbines, Sandia National Laboratories researchers have developed a fundamentally new type of rotary electrical contact. Most of the current utility-scale wind turbines are dependent on rare-earth magnets, Koplow said. 1 milliohm).
