Toyota Looking to Develop Rare Earth-Free Electric Motors

Rare-earth minerals such as neodymium and dysprosium are used in motor magnets that power hybrids and electric cars.

Toyota Motor Corp., the world’s largest seller of hybrid autos, is developing an alternative motor for future hybrid and electric cars that doesn’t need rare-earth minerals at risk of supply disruptions.

Toyota engineers in Japan and the U.S. are working on a so- called induction motor that’s lighter and more efficient than the magnet-type motor now used in its Prius, said John Hanson, a company spokesman. Research is at an “advanced stage,” he said, without saying when vehicles with the motors may be sold.

“It’s a long-term approach,” said Hanson, who is based at Toyota’s U.S. unit in Torrance, California. “When you’re looking at a geopolitical issue like rare-earth supply, that can lead to developments that create very good solutions.”
