Rare-earth magnets are essential for electric motors in vehicles, drones, and trains, forming the backbone of modern, ...

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 ...

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 ...

Is the dependence on rare earths for electric vehicle motors soon to be over? A magnet-free innovation promises to enhance motor efficiency while being more environmentally friendly. Mahle, based in ...

When you think of electric motors, you usually think of magnets. But magnets are heavy, and good magnets can pose problems when you need lots of them. A technology called SESM (separately excited ...

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 ...

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 ...

Exploring Why This 17-Year-Old's Electric Motor Is Important. Permanent magnets are a critical resource for renewables, as the generators in some wind turbines and motors in electric vehicles rely on ...
