    • A superconductive rotor of a dynamoelectric machine comprising a rotor shaft, a support rim, a plurality of slot teeth (86) formed at the outer periphery of said rim, said teeth located between rotor slots, and a plurality of slot assemblies, one within each rotor slot. Each slot assembly comprises a plurality of stacks (72) of superconductors (60), each superconductor within a stack having insulation (74) on only two of its sides and being disposed one on top of another in a generally radial direction relative to the rotor shaft; a plurality of insulative separators (73), one between each pair of stacks; a top insulative strip (79) and a bottom insulative strip (80), respectively radially above and below said conductor stacks; and a side panel (77) on either side of the slot assembly and next to a slot tooth. Cooling channels are disposed on the surfaces of the separators.

    • A ferromagnetic member (21) of a movable part (2) is disposed on a side of a stationary part (1) such that the ferromagnetic member (21) faces a high temperature superconductor (11) of the stationary part (1). The high temperature superconductor (11) is brought into a superconductive state by cooling it to a temperature below a critical temperature in a magnetic field. The magnetic flux pinned to the high temperature superconductor (11) is caused to pass through the ferromagnetic member (21) so that an attractive force is generated between the high temperature superconductor (11) and the ferromagnetic member (21) to hold the movable part (2). When the ferromagnetic member (21) has a shape such that when the gap becomes lower than a predetermined value, the attractive force decreases, the movable part (2) can be stably suspended in a non-contacting manner, without the necessity of control, by the combination of the high temperature superconductor (11) and the ferromagnetic member (21).
    • 可动部件(2)的铁磁部件(21)设置在固定部件(1)的一侧,使得铁磁部件(21)面对静止部件(1)的高温超导体(11)。 通过将高温超导体(11)冷却至低于磁场临界温度的温度,使其成为超导状态。 引导到高温超导体(11)的磁通通过铁磁部件(21),使得在高温超导体(11)和铁磁部件(21)之间产生吸引力,以保持可动部分 (2)。 当铁磁构件(21)具有这样的形状,即当间隙变得低于预定值时,吸引力减小,可移动部件(2)能够以不接触的方式稳定地悬挂,而不需要控制, 通过高温超导体(11)和铁磁部件(21)的组合。
