  • Publication number: 20240006938
    Abstract: A stator-core fixing structure fixes a stator core to a housing. The stator-core fixing structure includes a plurality of outer peripheral surface portions, and a plurality of inner peripheral surface portions. The plurality of outer peripheral surface portions are included in an outer peripheral surface of the stator core and have outer diameters different from each other. The plurality of inner peripheral surface portions are included in an inner peripheral surface of the housing and have inner diameters different from each other. Each of the plurality of outer peripheral surface portions corresponds to a corresponding one of the plurality of inner peripheral surface portions. Each of the plurality of outer peripheral surface portions contacts the corresponding one of the plurality of inner peripheral surface portions.

  • Publication number: 20230228297
    Abstract: A thrust magnetic bearing includes a coil formed by winding a conductive wire, and a core that houses the coil. The core is provided with a refrigerant inlet and a refrigerant outlet. A refrigerant flow path connecting the refrigerant inlet and the refrigerant outlet is provided between the coil and the core. The refrigerant flow path is formed so that a refrigerant flowing from the refrigerant inlet to the refrigerant outlet mainly flows along the coil in a winding direction of the coil.

  • Patent number: 11454279
    Abstract: A thrust magnetic bearing includes a stator having a coil, and a rotor. The stator includes main and auxiliary stator magnetic-pole surfaces. The rotor includes main and auxiliary rotor magnetic-pole surfaces facing the main and auxiliary stator magnetic-pole surfaces. When an electric current flows in the coil, an electromagnetic force in an axial direction is generated between the main stator and rotor magnetic-pole surfaces, and an electromagnetic force in a radial direction is generated between the auxiliary stator and rotor magnetic-pole surfaces. When the rotor is displaced in the radial direction, a radial force that acts on the rotor between the auxiliary stator and rotor magnetic-pole surfaces is increased in a direction of the displacement, and a radial force that acts on the rotor between the main stator and rotor magnetic-pole surfaces is increased in a direction opposite to the direction of the displacement.

  • Patent number: 11313376
    Abstract: A thrust magnetic bearing includes a stator having a coil that produces a magnetic flux, and a rotor. The magnetic flux supports the rotor in a non-contact manner. The stator has main and auxiliary stator magnetic pole surfaces. The rotor has main and auxiliary rotor magnetic pole surfaces. The main and auxiliary rotor magnetic pole surfaces face the main and auxiliary stator magnetic pole surfaces. The auxiliary stator magnetic pole surface includes at least one first stator surface and at least one second stator surface, alternately arranged. The auxiliary rotor magnetic pole surface includes at least one first rotor surface, and at least one second rotor surface, alternately arranged. Nr?1 and Nt?2, with Nr representing a number of pairs of the first stator and rotor surfaces facing each other, and Nt representing a number of pairs of the second stator and rotor surfaces facing each other.
