Automakers and aerospace firms are accelerating rare-earth-free motor designs as dependence on neodymium becomes a liability.

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 ...

Recent patent disclosures indicate that BYD has strengthened its work on variable-flux permanent-magnet synchronous ...

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 ...

The electric motors that power today’s EVs rely on permanent magnets made using rare-earth metals such as neodymium. Rare earths are the 15 elements whose atomic numbers run from 57 to 71, plus ...

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 ...

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 ...

"Even though electric vehicles might help us in transition away from fossil fuels, they also create these new problems in terms of polluting and often unstable supply chains.” When I started my video ...

How the switched reluctance motor's (SRM) architecture eliminates the need for magnets and rotor windings. Why SRMs are some of the most rugged and cost-effective motor technologies available. A look ...

MUNICH, Germany—ZF unveiled an electric motor that does not require magnets or rare earth materials, reducing reliance on mining in countries such as China and cutting manufacturing's carbon footprint ...

The trend in the automotive industry is to replace mechanically actuated systems with systems based on electric motor technology. The traditional brushed dc motor is not suitable for many of these ...
