Permanent Magnet AC motors hold the largest market share because they are more efficient, have a higher torque-to-weight ratio, and perform better in variable speed applications than other motors.

It's not surprising that the powertrains of electric cars differ quite a bit from traditional internal-combustion engines. Although they have fewer moving parts, the rare-earth magnets that help power ...

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 ...

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 ...

When you think of electric motors, you usually think of magnets. But magnets are heavy, and good magnets can pose problems when you need lots of them. A technology called SESM (separately excited ...

Continuing headlines about superefficient electric drives might lead some observers to wonder about the future of three-phase induction motors. The truth is that induction motors aren’t going away any ...

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 ...

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 ...
