    摘要: Die Erfindung betrifft eine elektrische Maschine mit einem Läufer in einem ortsfesten Maschinengehäuse, der eine supraleitende Erregerwicklung und ein zylindrisches Wellenendstück enthält. Um das Wellenendstück ist ein nicht-rotierendes Anschlußkopfteil angeordnet. Zwischen diesen Bauteilen sind ein Lager und eine Dichtungsvorrichtung vorgesehen und wird ein Kühlmittel übergeleitet. Der Läufer einer solchen Maschine führt axiale und radiale Schwingungen aus. ist der Anachlußkopf starr mit dem Maschinengehäuse verbunden, muß die Dichtungsvorrichtung ein entsprechendes Spiel ermöglichen. Dies führt jedoch zu Abdichtungsschwierigkeiten. Die Erfindung sieht deshalb ein Lager (22; 25) mit so geringem radialen Spiel vor, daß das Anschlußkopfteil (2) den radialen Auslenkungen des Wellenendstückes (3) aus dessen Sollage bezüglich einer Rotationsachse (4) folgt. Die Dichtungsvorrichtung (29; 30) kann dann vorteilhaft eine Ferrofiuidikdichtung (50 bis 52) sein. Als Lager (22; 25) kommt insbesondere ein Gleitlager in Frage. Entsprechend gestaltete Anschlußkopfteile können für supraleitende Turbogeneratoren vorgesehen werden.

    摘要: The superconducting rotor (10) includes at least one field coil (12) made of a superconductor material having a given superconducting transition temperature. A cryocooler system is mounted for rotation with the rotor (fig. 2). The cryocooler includes a cold head portion (24) mounted in heat transfer relation with the field coil (12) to cool the field coil to a temperature below its transition temperature and includes a piston/regenerator (42), (figs. 3, 4 and 5) adapted to allow passage of a working fluid at a mass flow rate which is substantially uniform over the cross section of the piston/regenerator during the operation of the system. Heat is conducted away from the field coils (12) by heat pipes (80) or by conduction through high thermally conductive material. Mounting the cryocooler cold head (24) for rotation with the rotor eliminates the use of a cryogenic liquid pool for rotor cooling.

    摘要: A rotary member (2) is continually held suspended in the space by a strong pinning force (fishing effect) of high temperature oxide superconductors (1) under superconductive state. The magnetic field of the magnets (3) on thus suspended rotary member (2) is distributed concentrically about the center of the pinning force, so that the rotary member can be continually rotated in a non-contact state while being lifted off the high temperature oxide superconductors (1).
    Thus, by utilizing the external energy via an input/output device (10,11), the theory member (2) is rotated in a vacuum tank (6) under highly vacuum state and is held continually rotating for an extended period of time.
    By taking out the kinetic energy of rotary member via the input/output device, the stored energy can be taken outside.

    摘要: An electric rotary machine (for example, a dynamoelectric machine) having a superconducting rotor is disclosed in which an outer shielding member (3) for protecting a superconducting field winding (5) from the influence of the magnetic fluid from the stator side and for interrupting heat radiated from the normal temperature side is made of a nickel alloy containing not more than 0.3% carbon, not more than 1% silicon, not more than 2% manganese, not more than 1.5% titanium, from 2 to 8% aluminum, from 8 to 40% copper, and not less than 55% nickel for the balance by weight. The nickel alloy has a structure that a y'-phase precipitation is formed by aging in an austenitic matrix, and is non-magnetic at 20°C.
