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 ...

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 ...

Toachieve systems design goals, where motors are involved, of increasedefficiency and improved power density, along with lower noise and variablespeed operating capability, technologies beyond ...

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 ...

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 ...

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 ...
