Researchers at China's National University of Defense Technology (NUDT) have accelerated a one-ton vehicle from a dead stop ...

Abstract: This paper proposes an analytical method to calculate magnetic field of nonlinear spoke-type permanent-magnet motors (STPMM) considering static, dynamic, mixed rotor eccentricities and pole ...

The Trump administration invested a lot of time during 2025 trying to set up deals to establish rare-earth supply chains that do not depend on China. This effort started puzzlingly, with some ...

Discover how to build a simple electric train using just a copper coil, an AA battery, and disc magnets in this step-by-step ...

As Beijing's new licensing rules on samarium and related materials restrict exports of these heat-resistant magnets, America's ability to produce precision-guided munitions has come under pressure.

Automakers and aerospace firms are accelerating rare-earth-free motor designs as dependence on neodymium becomes a liability.

Abstract: Inherent levitation eccentricity, which results from sensor detection errors, is an inevitable problem in bearingless permanent magnet synchronous motor (BPMSM) systems. It will drastically ...

The RTV 31 hovertrain was expected to be even faster than Japan’s bullet train, but now it is rotting beside a railway line ...
