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.

By removing rare earths from the equation, these designs promise cleaner supply chains and more sustainable production.

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 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 ...

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 ...

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 ...

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 ...

Electric motors have only one moving part, but a look into the three types and how each works proves they are far from simple ...
