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

Never mind present-day’s bonny blather on the benefits of electric, hydrogen and biofuel power. How do you feel about magnets? Better make up your mind, stat; as of this morning, a company named ...

Compromise is key to keeping a team humming along. Say one person wants an inrunner electric motor, and the other prefers ...

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 ...

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 ...

The design also opens up a pathway for massive weight reduction in EV design. YASA said that deploying the in-wheel motors in lieu of a traditional power and drivetrain could save around 440 pounds ...

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 ...
