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 ...

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 ...

This video is an animation of the principle behind PI’s magnetic linear motors. The magnetic linear motors correspond to a sequence of a number of voice-coil actuators; individual coils can be ...

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 ...

This study focuses on the direct-drive ultrasonic resonant motors called PILine ® motors. Their direct-drive design enables ultra-low response times and highly precise positioning without any backlash ...

MUNICH, Germany—ZF unveiled an electric motor that does not require magnets or rare earth materials, reducing reliance on mining in countries such as China and cutting manufacturing's carbon footprint ...

LONDON (Reuters) - Tesla's shift to a magnetic motor using neodymium in its Model 3 Long Range car adds to pressure on already strained supplies of a rare earth metal that had for years been shunned ...
