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

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 ...

Magnets, typically using rare earth metals like neodymium, are found at the heart of most electric vehicle motors. It's nice to have a permanent source of powerful rare earth magnetism in your rotor, ...

The leading German tech giants over at Mahle have developed an electric motor that doesn’t use permanent magnets. It has the potential of powering a wide range of vehicles, it’s highly efficient, and ...

Nearly 40 years ago, General Motors invented the rare-earth magnet and thus laid the foundation for modern electric motors. But now the automaker is moving on to a different technology. GM recently ...

We last caught up with Equipmake back in 2018, when this British company's spoked magnet electric motors were capable of generating a monster 9 kilowatts of power per kilogram, using cheap materials ...

The high-energy-product neodymium rare-earth permanent magnet (RE-PM) was discovered in the early 1980s. Later, dysprosium doping emerged to provide reasonable RE-PM magnetization life by sacrificing ...

Nikesh Kooverjee has been contributing to the automotive sphere for 11 years. His previous roles include Digital Editor at CAR South Africa and associate editor at CarBuzz. He has always had a strong ...

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 ...
