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

While electric vehicles certainly offer a host of eco-friendly advantages, they're not without some asterisks, one being the rare earth materials (and harmful mining thereof) used to make the magnets ...

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 ...

Permanent magnet synchronous motors (PMSMs) are widely recognised for their efficiency and performance in applications ranging from electric vehicles to industrial machinery. However, the generation ...

There is a constant need and desire throughout the HVAC industry to spur innovation and create new products and ideas that can redefine the marketplace. In the realm of motors, the permanent magnet ...

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 ...

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 ...

Toyota says it has invented a new magnet for high-energy applications like electric motors that uses a fraction of the amount of neodymium (a rare-earth element) of a standard iron, boron, neodymium ...

It turns out the most abundant rare earth we have, cerium, can substitute for dysprosium when properly co-alloyed with cobalt. That's good news for the motor business. Share on Facebook (opens in a ...

DYSPROSIUM and neodymium are not exactly the best-known elements in the periodic table, but for makers of high-end electric motors they have become vital. Both are strongly magnetic and thus crucial ...
