Automakers and aerospace firms are accelerating rare-earth-free motor designs as dependence on neodymium becomes a liability.

China controls about 90% of the entire global supply of rare earth magnets, including their mining and refining. That means that most of the neodymium, dysprosium, and terbium that end up in EV motors ...

Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

Weary of being captive to geopolitics, car companies are looking for ways to replace powerful rare-earth magnets in electric motors. BMW is using motors without ...

MUNICH, Germany—ZF unveiled an electric motor that does not require magnets or rare earth materials, reducing reliance on mining in countries such as China and cutting manufacturing's carbon footprint ...

It turns out the most abundant rare earth we have, cerium, can substitute for dysprosium when properly co-alloyed with cobalt. That's good news for the motor business. Share on Facebook (opens in a ...

Several companies around the globe have been hard at work innovating and refining magnet-free electric motors to make them a more viable option for the fast-growing EV industry. ZF Friedrichshafen has ...

Did you know GM invented the domestic, affordable permanent magnet? Before this neodymium-iron-boron magnet came along in 1984, electric motors, generators, audio speakers, hard-disk drives, and the ...

How often have you had conversations with friends about electric vehicles where you talked about their engines? Here's a fun fact. EVs do not have engines. They have motors or, to be more specific, ...

Last month, at a livestreamed Tesla investor event that went short on new cars and long on grandiose narratives, a minor detail in Elon Musk’s “Master Plan Part 3” made big news in an obscure corner ...
