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 ...

A new bipartisan bill aims to boost U.S. rare earth magnet production, highlighting a critical supply chain dependency inside drone motors.

Experiment Electric Motor of Magnetic Rotor in Motion ...

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 ...

Perpetual motion machine magnet motor ...

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 ...

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

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 ...

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 ...
