The invention relates to a mounting for a turbo-machine rotor. Said mounting is characterized in that radial support of the rotor is assured by one or more permanent magnet bearings. One or more single-thrust sliding bearings provide axial support. The permanent magnet bearings also serve as a lifting device for the sliding surfaces of the hydrodynamic sliding bearings. A force, acting in the opposite direction from the axial force, is generated by axial displacement of the rotor-sided bearing elements of the permanent magnet bearing, in relation to the housing-sided bearing elements, counter to the direction of axial force. This force separates the sliding surfaces of the hydrodynamic sliding bearings from each other in the stopping phases of the rotor. Once it has come to a stop, and when it is in the starting and stopping phases, the rotor is guided by one or more sliding or rolling bearings. These are so configured that, at low rotational speed and when at a standstill, they have a substantially lower moment of friction than the hydrodynamic sliding bearings used in the mounting.

The present invention relates to a magnetic suspension bearing supported by magnetic force, which comprises one or more magnets fixed on a shaft directly or indirectly which can rotate with said shaft, and matching magnets provided in a certain space, wherein the magnetic polarity and magnitude of magnetic force of the matching magnets match with the magnetic polarity and magnitude of magnetic force of said one or more magnets to achieve the full suspension rotation of said shaft, and said magnets and/or matching magnets are permanent magnets. The present invention is of simple design and large power, with many other advantages such as great rigidity and great load-bearing capability and widely use in various fields.

A magnetic bearing system for a rotating machine is disclosed. The magnetic bearing system provides a non-contacting radial rigid support for the rotating machine by employing two magnetic assemblies each being formed by stacked annular magnets. The magnetic assemblies are mounted separately on a shaft of the rotating machine and a shaft hole provided on the stator seat of the rotating machine for containing the shaft.

Bearing device of magnet type for instruments and the like and non-contact support of one part relatively to another part by means of magnet fields wherein the one part is rotatable relatively to the other at least a part of a full turn. The novelty lies therein that the magnet devices intended to keep the rotatable part essentially centered relatively to the stationary part are off-set so that besides radially acting force components also axial force components biasing the rotatable part in an axial direction appear; and in that a connection device connecting the rotatable part with the stationary part and permitting the former to turn at least a portion of a turn is arranged along the axis of rotation so as to keep the rotatable part correctly off-set positioned.

The subject invention concerns an article of manufacture, which can be in various shapes and forms as disclosed herein, based on the principle of magnetic levitation. When motion is applied to the article of manufacture, there results a body moving through the air without mechanical support. This invention can be used for many purposes including entertainment and educational uses.
