The NEC defines a controller in a few different ways. In Art. 100, a controller is described as “a device or group of devices that serves to govern, in some predetermined manner, the electric power ...

Never mind present-day’s bonny blather on the benefits of electric, hydrogen and biofuel power. How do you feel about magnets? Better make up your mind, stat; as of this morning, a company named ...

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 ...

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 ...

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.

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 ...

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 ...

For decades, permanent magnets have been one of the least questioned links in the electrification supply chain.
