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 ...

General Motors and Stellantis are hoping to fix a glaring hole in their electric vehicle roadmaps, with the two automakers setting their sights on a US-made magnet tech that could upend the motors ...

The automaker is teaming up with a small Minnesota-based startup to develop iron nitride-based magnets in the hopes of localizing a key aspect of its EV motor production. The automaker is teaming up ...

While electric vehicles certainly offer a host of eco-friendly advantages, they're not without some asterisks, one being the rare earth materials (and harmful mining thereof) used to make the magnets ...

Nearly 40 years ago, General Motors invented the rare-earth magnet and thus laid the foundation for modern electric motors. But now the automaker is moving on to a different technology. GM recently ...

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 ...

Electric motors are everywhere—from the cars we drive to the appliances in our homes—but most rely on rare earth magnets that come with high costs and environmental challenges. A new wave of ...

China's grip on global supply chains is turbocharging efforts to find alternatives to the small group of metals that dominate EV motor technology ...

Two great minds in permanent-magnet-free motor design are fusing their know-how to create an even more capable inductive electric motor. Mahle and Valeo have teamed up to introduce what they call the ...

Rarely a week went by in 2025 without some newsworthy development related to rare earth elements, magnets, and electric motors. IEEE Spectrum was on top of the big ones, starting with the production ...
