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

The switch to a neodymium-intensive permanent magnet motor in a volume model like the Model 3 has some worried about long-term supply issues. Kyle Hyatt (he/him/his) hails originally from the Pacific ...

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 ...

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 ...

The global price of energy is at an all-time high, with few signs of relief in sight, making consumers and businesses alike interested in energy conservation. Currently, the most common motor type in ...

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 ...

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 ...

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 ...

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 ...

There seems to be some confusion within the industry about the terms “permanent magnet synchronous motors” (PMSMs) and “brushless DC (BLDC) motors”. I’ve talked with several different application ...

When was the last time you stopped to think about how electric cars actually work? We superfans of the car biz have mostly developed a reasonable understanding of how combustion powertrains work. Most ...
