Rotating Shaft - an overview | ScienceDirect Topics
In a magnetic bearing the rotating shaft is supporting in a powerful magnetic field, Fig. 3.15. As with the air bearing gives a nuer of significant advantages, no wear between the rotating and stationary parts, thus particle generation is eliminated, therefore magnetic bearings are particularly suited to clean room appliions.
Turbo blowers - AERZEN
AERZEN uses air for Non-Contact bearing system. The air bearing is used as standard solution in the Turbo Blowers of the AT and TB Series. The value of non-contact air bearings has enormous advantages over mechanical and magnetic solutions. Functioning value and operation features within the turbos are based on very simple physical principles.
Analytical Calculation of the Magnetic Field Distribution in a Linear and Rotary Machine with an Orthogonally Arrayed Permanent Magnet
magnetic field distributions are analytically determined. In [20], a precision equivalent magnetic circuit analysis of a five-degree-of-freedom hybrid magnetic bearing was proposed in consideration of the non-uniform distribution of magnetic density. Reference [21
Position, Distance and Bearing Calculations
For exampe, if the true bearing is 10 , the magnetic bearing would be (10 – 22 + 360 =) 348 . Similarly, a measured bearing of 95 magnetic would be equivalent to (95 + 22 =) 117 true. If more than a few sites are being evaluated, it can be more

What is a Rotor - Types, Working, Functions & Appliions
An electrical rotary drive, designed as a bearingless motor, has a magnetically journalled rotor ( 3 ) and a stator ( 2 ) which comprises a drive winding ( 6 ) having at least two loops ( 61, 62 ) for producing a magnetic drive field which produces a torque on the rotor

Magnetic Bearings - an overview | ScienceDirect Topics
Magnetic Bearings. Magnetic bearings react differently than hydrodynamic or rolling-element bearings in that the mechanical bearings react immediately to a load change while the magnetic bearing in line with the load change must increase its force at the same rate to maintain rotor position. From: Compressors (Third Edition), 2005.
