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 ...

In a world filled with high-tech robotics kits and programmable gadgets, one artist decided to strip everything back to the fundamentals of physics. Jamie from the YouTube channel Jamie’s Brick Jams ...

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 ...

The leading German tech giants over at Mahle have developed an electric motor that doesn’t use permanent magnets. It has the potential of powering a wide range of vehicles, it’s highly efficient, and ...

Electric motors are everywhere—from the cars we drive to the appliances in our homes—but most rely on rare earth magnets that come with high costs and environmental challenges. A new wave 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 ...

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 ...

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 ...

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 ...
