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 ...

Cages/retainers are almost always utilized to maintain uniform roller loading and spacing. Although fluid bearings and magnetic bearings are also manufactured for thrust applications, these areas are ...

The basic principle is this: to correct for declination, you want the map bearing and the magnetic bearing to be equivalent. If you are lucky enough to be on the line where the declination is 0°, both ...
