The number of interesting and innovative mechanisms that 3D printing has enabled always fascinates us, and it’s always a treat when one of them shows up in our feeds. This axial flux magnetic gearbox ...

Gravity basically doesn’t factor into a new style of rotation-based magnetic levitation being developed. This spin-stabilized levitation uses a rotating magnet to steady the levitating magnet and lock ...

Magnetic levitation demonstrated using a Dremel tool spinning a magnet at 266 Hz. The rotor magnet is 7x7x7 mm3 and the floater magnet is 6x6x6 mm3. This video show the physics described in the work ...

This file type includes high resolution graphics and schematics when applicable. The simplest axial magnetic gearboxes consist of two disks each containing alternating positive and negative magnets ...

Continuing headlines about superefficient electric drives might lead some observers to wonder about the future of three-phase induction motors. The truth is that induction motors aren’t going away any ...
