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 ...

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 ...

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 ...

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 ...

"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 ...

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

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 ...

Automakers are racing to redesign the heart of the electric vehicle, the traction motor, so they can cut their dependence on rare earth metals without sacrificing performance. BMW, General Motors and ...

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 ...
