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 ...

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 ...

"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 ...

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 ...

Vimag Labs secures $5 million to advance its innovative magnet-free motor technology for automotive and industrial ...

AUSTIN, Texas--(BUSINESS WIRE)--3M today announced a new magnet bonding adhesive system designed to provide electric motor design and manufacturing engineers with an advanced tool for bonding ...

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 ...

Magnetic couplings transmit high torque with no physical contact, and they disengage smoothly when load gets too high. Generally speaking, the couplings use magnetic power in three different ways; ...

This file type includes high-resolution graphics and schematics when applicable. In the seemingly endless quest for higher motor performance and improved system cost efficiencies, motor manufacturers ...

Christian Ruoff, writing in Charged, tells us that the most likely explanation has to do with historical factors. By many accounts, the reason Tesla started developing an induction motor in the first ...
