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

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 ...

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 ...

Tesla will create a permanent magnet electric vehicle motor with zero rare earth elements in it, the company announced at its Investor Day today. Rare earth elements are a bone of contention in EV ...

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 ...

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 ...

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 IronHorse permanent-magnet dc 56C-frame motors feature totally enclosed nonvented (TENV) and totally enclosed fan-cooled (TEFC) models. Constructed of a rolled-steel frame with cast-aluminum end ...

Tesla made a significant change to its electric motor strategy with the introduction of the Model 3, switching from an AC induction motor to a permanent magnet motor. Now, Tesla’s principal motor ...

GM and Niron have teamed up to pry the EV motor material supply chain away from China. Did you know GM invented the domestic, affordable permanent magnet? Before this neodymium-iron-boron magnet came ...
