摘要： A magnetic bearing wherein axially spaced combinations of permanent magnets on a rotor and stator are polarized to levitate the rotor and positioned with the rotor magnets offset axially outwardly (or inwardly) of the stator magnets to allow a force balance to be achievable to bear axial thrust. An electrically energizable coil modulates magnetic flux between the respective stator and rotor magnets for each combination. A first electrical circuit regulates electrical energy to the coils for maintaining a reference position of the rotor. A second electrical circuit compares feed-back of electrical energy to at least one of the coils with a reference electrical energy of about zero amps or volts and integrates the differences until the difference is about zero to provide a signal to modify the reference position, whereby to attain a zero force balance position wherein the current which must be supplied to the coils may be reduced to near zero.

摘要： A mass is levitated with respect to a base, at least one of which is comprised of a diamagnetic material, with the levitated mass also having a permanent magnetic property. A second permanent magnet is optionally configured such that it attracts the levitation mass away from the base to overcome gravitational force on the mass, thereby suspending the mass over the surface of the base. The mass is contained in a nonmagnetic, non-shielding and optionally optically-transparent housing so as to limit its excursion within a range of levitation positions. A position measurement means such as a laser interferometer, capacitance detector, or pickup coil is configured to measure positional deviations of the mass in response to incident pressure wave, the output of which being an electronic signal representing the pressure wave.

摘要： A magnetic bearing includes at least one inner bearing part; at least one outer bearing part which surrounds the inner bearing part; at least one permanent magnet and at least one flux guiding element which is positioned axially in relation to a rotation axis, adjacent to the permanent magnet(s), for guiding the magnetic flux of the permanent magnet(s) to one of the two bearing parts, and at least one superconductor on the other of the two bearing parts. The permanent magnet(s) and superconductor interact with each other in such a way that a bearing gap is formed around the rotation axis between the inner bearing part and the outer bearing part. The permanent magnent(s) is/are radially set back towards the bearing gap in relation to the flux guiding element(s) in a radial direction, perpendicular to the rotation axis. Each permanent magnet is held at least one of inwards and outwards by a corresponding radial holding element, at least on the facing towards the bearing gap.

摘要： A method for the excitation of the radial force and torque winding systems of electrical drives with integrated magnetic bearings. The drives comprise an electrical machine with torque and radial force windings which are introduced in the stator or rotor, a position and angle sensor system and analog or digital electronic circuitry for the control, regulation, monitoring and feeding of the machine. A model is used for setting the rotor position (36,37) and the rotational angle of the rotor (&phgr;) which describes the relationship between the forces acting radially and tangentially at the rotor or at the stator respectively and the loop currents, and indeed in such a manner that it takes into account the deviations from the sinusoidal form of the force components, which depend on the rotational angle of the rotor (&phgr;).
