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 ...

Chinese EV maker BYD has disclosed four patents detailing variable-flux permanent magnet synchronous motor technology.

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 ...

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 ...

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 ...

Explore the fascinating world of perpetual motion through a deep dive into magnet motors. This video unveils the science and theories behind building a perpetual motion machine and magnet motor, ...

MP’s initial magnetics facility in Fort Worth, Texas, will source materials from Mountain Pass, California, restoring a fully integrated U.S. supply chain MP has entered a long-term agreement with ...

In 1960, the large-angle type PM step motor was the most used step motor. This two-phase, bifilar wound PM step motor (top) advanced 45° mechanical with each pulse from the drive, while by 1962 PM ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...
