The difference here is that rather than low-friction sapphire bearings, this motor uses zero-friction magnetic levitation using pyrolyzed graphite discs. The diamagnetic material hovers above a ...

hence the motor’s name. The rotor is a styrofoam sphere with neodymium magnets embedded around its equator. A sharpened bicycle spoke serves as an axle, and clever magnetic bearings provide near ...

Additionally, the integration of magnetic geared motors with bearingless designs has been explored to address durability issues associated with mechanical bearings in high-speed applications.

Permanent magnet is an object made up of ferromagnetic material, which has magnetic properties and creates its own magnetic field. Permanent magnet motors are manufactured using permanent magnets in ...
