Magnetic bearings use an electromagnet to provide non-contacting, friction-free motion in rotary applications. They are constructed of a rotating and a stationary part (rotor and stator, respectively) ...

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 ...

A sharpened bicycle spoke serves as an axle, and clever magnetic bearings provide near-zero friction rotation. The stator coil comes from an old solenoid and is driven by a very simple two ...

Avionics systems also rely on ultra-quiet bearings to avoid disrupting the accuracy of sensitive navigation and control ...
