A magnetic bearing is a bearing that supports a load using magnetic levitation. Magnetic bearings support moving parts without physical contact. For instance, they are able to levitate a rotating shaft and permit relative motion with very low friction and no mechanical wear. Magnetic bearings support the highest speeds of all kinds of bearing and have no maximum relative speed.
Passive magnetic bearings use permanent magnets and, therefore, do not require any input power but are difficult to design due to the limitations described by Earnshaw's theorem. Techniques using diamagnetic materials are relatively undeveloped and strongly depend on material characteristics. As a result, most magnetic bearings are active magnetic bearings, using electromagnets which require continuous power input and an active control system to keep the load stable. In a combined design, permanent magnets are often used to carry the static load and the active magnetic bearing is used when the levitated object deviates from its optimum position. Magnetic bearings typically require a back-up bearing in the case of power or control system failure.
EAAT has been developing and producing magnetic bearings with wide ranging requirements for customers in the areas of industry, materials testing and scientific research.

A Magnetic Bearing Made With Permanent Magnets
In this video we show a passive magnetic bearing made with permanent magnets. It is a very basic structure similar to the ones used in actual motors with magnetic bearings.
The permanent magnets distributed in a half circle shape provide a suspension force to the rotor. Even though those magnets make the rotor levitate in a centered position, they are not able to provide damping to radial oscillations and cause unstable forces in the axial direction.
In this experiment, the rotor position is restricted by a mechanical contact, similar to the tip of a spinning top.

NCSU - ECE535 - Demo of a Permanent Magnetic Bearing
In this video I demonstrate a permanent magnetic bearing. I describe the equations that can be used to calculate forces between permanent magnets and how Earnshaw's Theorem describes why this system is unstable without a physical contact point. Finally I describe how I built the bearings and demonstrate their operation.
