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 ...

Several companies around the globe have been hard at work innovating and refining magnet-free electric motors to make them a more viable option for the fast-growing EV industry. ZF Friedrichshafen has ...

Boosting energy efficiency in hazardous areas is critical for operators seeking to reduce their operating costs while also ...

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 ...

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 ...

A number of readers questioned the veracity of the technology presented in this article. To address their concerns, we did a follow-up, which can be found here. Permanent magnets are an integral part ...

If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is ...

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 ...
