A broken motor in an automated machine can bring production on a busy factory floor to a halt. If engineers can't find a ...

Hobby servos are nifty and useful for a wide range of projects. There’s nothing stopping you from building your own servos though, and you can even give them nifty features like 360-degree rotation In ...

We last caught up with Equipmake back in 2018, when this British company's spoked magnet electric motors were capable of generating a monster 9 kilowatts of power per kilogram, using cheap materials ...

It used to be a staple of junior high physics class to build some sort of motor with paperclips or wire. A coil creates a magnetic field that makes the rotor move. In the process of moving, brushes ...

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 ...

Tesla made a significant change to its electric motor strategy with the introduction of the Model 3, switching from an AC induction motor to a permanent magnet motor. Now, Tesla’s principal motor ...

China controls about 90% of the entire global supply of rare earth magnets, including their mining and refining. That means that most of the neodymium, dysprosium, and terbium that end up in EV motors ...

Ahead of releasing all the specs and opening orders for the Model 3 dual motor and performance versions, Tesla CEO Elon Musk has been slowly releasing some details about the new versions of the ...

As an engineer working with electric motors and generators, I've kept an eye open for software that more completely analyzes these machines. Maxwell Version 10 may end the search. lt uses finite ...
