When we hear about moving objects with electricity, most of us imagine a "pulling force." Positive and negative charges ...

What if the very principles that have powered industry for over a century were suddenly turned on their head? For decades, electromagnetic motors—reliant on copper windings and rare earth magnets—have ...

Electrostatic motors are now common in MEMS applications, but researchers at the University of Wisconsin and spinoff C-Motive Technologies have brought macroscale electrostatic motors back. [via ...

Electric motors usually comprise a stator and a rotor, with the latter rotating inside the former. Donut Lab thinks this design is outdated, and a hollowed-out rotor can offer important advantages.

Scientists at the Korea Institute of Science and Technology (KIST) have developed a new class of lightweight, highly conductive carbon nanotube (CNT) wiring that does away with copper and aluminum ...

This remarkable miniature rotorcraft is so lightweight and efficient that it can lift its own mass given nothing but sunlight. The entire thing weighs about as much as four paperclips, and it can fly ...

Yasa’s yokeless dual-rotor motor design with a threefold power-density gain, points toward lighter, more efficient ...
