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 ...

We see our share of pitches for perpetual motion machines in the Hackaday tips line, and we generally ignore them and move along. And while this magnetic levitation motor does not break the laws of ...

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 ...

In a children’s playground project featuring dynamic dancing fountains, the SplashBotix division of ARM Automation faced a ...

Toachieve systems design goals, where motors are involved, of increasedefficiency and improved power density, along with lower noise and variablespeed operating capability, technologies beyond ...

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 ...

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 ...
