When viewed in the direction of the rotational axis C1 of the rotor 20, the magnetic pole center side of the bulk superconductors 30 is disposed nearer to a stator 10 than the magnetic pole end side of the bulk superconductors 30. A ferromagnet 28 is disposed on the rotational axis C1 side of the bulk superconductors 30. A magnetizing apparatus 100 is disposed outside the bulk superconductors 30 in the radial direction of the rotor 20. Magnetization of the bulk superconductors 30 is performed by directing magnetic flux lines from the magnetizing apparatus 100 toward the bulk superconductors 30.

In this structure, the rotary machine can stably maintain the capability of thermal transport between the condenser section and the evaporator section, even in a case where the whole of the rotary machine is tilted or shakes.
