摘要： A magnetic thrust bearing for use in a device for relatively free rotational movement of a first part relative to a second part includes axial and laterally spaced magnets. Each magnet has a magnetic field of force with opposing poles and a transition section which converges to a transition line. Axial magnets are spaced on an axis of the first part of the device and lateral magnets are arranged on the second part of the device. The lateral magnets operating in units, having paired lateral magnets positioned on opposite sides of the axis with each of the paired magnets having an equal length and equal gap or space from the axis. Axial magnets have an alternating polar orientation such that the nearest magnetic poles of adjacent axial magnets are repelling, and the distance between transition lines of the axial magnets is substantially equal to the length of the lateral magnets. Accordingly, the magnetic field of force of each lateral magnetic unit is perpendicular and attracting to the repelling fields of force between adjacent axial magnets for lateral displacement of the first part relative to the second part by a fixed gap, so that, with this arrangement, the permanent-magnet bearing enables non-contact, relative motion between the two parts of the device using both attractive and repelling forces generated by magnets.

摘要： Featured is a method for passively-repulsively lifting a rotor assembly (11) of a flywheel energy storage system (10), comprising the steps of mechanically coupling a first permanent magnet (204a) to the rotor assembly (11) and fixedly positioning a second permanent magnet (204b) proximal to the first permanent magnet (204a) so that a repulsive force is generated therebetween causing the first permanent magnet (204a) to move with respect to the second permanent magnet (204b), thereby causing the rotor assembly (11) to be lifted to an operating level. The method further includes applying a radial force sufficient in magnitude and direction to oppose a radial force being generated by the permanent magnet repulsive force. Also featured is a passive-repulsive rotor assembly lift system (100) for a flywheel energy storage system (10) and a flywheel energy storage system (10) including such a repulsive rotor lift system (100).

摘要： A rotatable hub in which a supporting shaft having hydrodynamic pressure generating grooves is inserted comprises an annular thrust bearing plate in its lower portion and annular permanent magnets in its upper portion. The thrust bearing plate is inserted between the lower end face of the supporting shaft and a thrust flange fixed to the supporting shaft, maintaining the respective clearances D and E.The permanent magnets on the hub are confronting in such a manner that an upward and downward repulsive forces are generated between permanent magnets mounted on the supporting shaft, respectively maintaining the clearances B and C. Since the clearances B and C are greater than the clearances D and E, the permanent magnets will not mutually contact even when the hub is caused to move upward or downward by an external force during rotation and the thrust bearing plate contacts with the lower end face of the supporting shaft or the thrust flange.

摘要： A fluid pump with rotary impeller is disclosed which comprises an electromagnetically-driven, bearing-free, seal-free rotary impeller levitated by localized opposed, repulsive, permanent magnetic forces and by fluid forces, or by localized opposed repulsive magnetic forces only. Levitation by localized opposed magnetic or magnetic and fluid forces of an impeller driven by electromagnetic forces eliminates the need for bearings and seals in the driving mechanism. This avoids the heat build-up and leakage associated with other pumping mechanisms, which can be of importance in pumping of physiological fluids such as blood. The levitating forces of the present invention are applied repulsively both axially and radially with respect to the impeller and are auto-adjusting, such that any attempted displacement of the impeller will automatically incur a corrective change in levitating forces. The invention should be of use in numerous medical and non-medical applications where the benefits of impeller levitation by localized forces are apparent.
