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 ...

Magnetic Bearing Chiller Helps Maximize Cooling Capacity with a Reduced Footprint The new air-cooled chiller, based on Trane's proven Magnetic Bearing compressor platform, produces up to 850 tons ...
