A pole core portion which between each of the permanent magnets and an outer surface of the rotor core is provided with a plurality of pole slits. A region of the pole core portion is defined by concave portions provided on q-axes to be interpolars on both sides of the pole core portion, and thereby configured that a gap between the outer surface on the q-axis of the rotor core and an inner surface of the stator core is larger than a gap between the outer surface on the d-axis of the pole core portion and the inner surface of the stator, so that magnetic fluxes from the permanent magnet pass through the pole core portion concentrately.

摘要： A superconducting bearing device for supporting a rotary shaft (rotary body) 2 in a noncontact state for rotation at a high speed. A superconducting bearing 4 for supporting the rotary shaft 2 in a noncontact state relative to a housing 1 comprises permanent magnets 14 mounted on the rotary shaft 2, and Type II superconductors 17 attached to the housing 1 and opposed to the magnets as vertically spaced apart therefrom. A mechanical catcher bearing 21 comprising a thrust ball bearing is disposed between the housing 1 and the rotary shaft 2 at opposed portions thereof. An initial position determining mechanism is provided for lifting a bearing ring 23 of the catcher bearing 21 on the housing 1 to position the housing 1 and the rotary shaft 2 in place relative to each other, whereby the superconductors 17 and the permanent magnets 14 on the shaft 2 can be positioned in place relative to each other. The superconducting bearing 4 can be operated efficiently by suitably determining the relative position. The catcher bearing 21 prevents damage to the rotary shaft 2 and parts therearound when the superconductors 17 of the bearing 4 become normally conductive.

摘要： A superconducting bearing device includes a permanent magnet on a rotor, with a superconductor placed opposite the magnet. Flux trapped in the superconductor during cooling helps to stabilize the rotor. More specifically, the permanent magnet is mounted on the rotor so that, as the rotor rotates, its rotation does not alter the magnetic flux distribution around the axis of rotation of the rotor. The superconductor permits penetration of the magnetic flux from the magnet, being spaced from the magnet by a distance that permits a predetermined quantity of the magnetic flux to penetrate it, while not permitting rotation of the rotor to alter the distribution of the penetrating magnetic flux.
