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 ...

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 ...

IE5+ permanent magnet synchronous motors (PMSM) from NORD Drivesystems deliver the highest energy efficiency available in the ...

We see our share of pitches for perpetual motion machines in the Hackaday tips line, and we generally ignore them and move along. And while this magnetic levitation motor does not break the laws of ...

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 ...

LONDON (Reuters) - Tesla's shift to a magnetic motor using neodymium in its Model 3 Long Range car adds to pressure on already strained supplies of a rare earth metal that had for years been shunned ...

A number of readers questioned the veracity of the technology presented in this article. To address their concerns, we did a follow-up, which can be found here. Permanent magnets are an integral part ...
