The global price of energy is at an all-time high, with few signs of relief in sight, making consumers and businesses alike interested in energy conservation. Currently, the most common motor type in ...

Permanent Magnet AC motors hold the largest market share because they are more efficient, have a higher torque-to-weight ratio, and perform better in variable speed applications than other motors.

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 ...

Inventors and fans have long been captivated by the concept of a magnetic engine, which uses magnets to create perpetual motion and power a vehicle without the need for fuel. Nevertheless, it is still ...

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 ...

The switch to a neodymium-intensive permanent magnet motor in a volume model like the Model 3 has some worried about long-term supply issues. Kyle Hyatt (he/him/his) hails originally from the Pacific ...

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 ...

Washington, D.C., has spent the past five years fixating on rare earths—where they’re mined, how they’re processed, and who controls the magnet supply chain. That attention is overdue. But the ...

With its Hunstable Electric Turbine, Linear Labs promises three times the torque, twice the power and a 10% increase in range in an electric vehicle over a typical permanent magnet motor. One problem ...

When you think of glass, you probably picture something fragile and brittle, not a material built for high-stress electromechanical components. However, researchers at Germany's Saarland University ...
