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 ...

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 ...

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 ...

As NACFE has so well coined the phrase, we are in the "messy middle", a time when there are many solutions to decarbonize trucking. They start with improving fuel economy of diesel-powered vehicles, ...

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 ...

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 ...

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 ...
