A superconducting machine is disclosed, in particular for use as a generator in a stand-alone power system. In at least one embodiment, the superconducting machine includes a stator and a rotor capable of rotating with respect to the stator. At least one superconducting coil for generating at least two magnetic poles is provided on at least one component part, in particular the rotor, which superconducting coil is cooled via a cooling device; and at least two parallel winding elements are provided on the respective other component part, in particular the stator, in the armature winding for each phase, which winding elements can be connected either in series or in parallel via at least one switching device.

The invention relates to an insulated container (11) which can be evacuated and has an application (12) to be cooled, in which insulated container (11) a vacuum can be built up by means of a vacuum pump (22). In order to allow the vacuum pump (22) to be switched off during normal operation, a getter material (26) is arranged in the insulated container and binds gas components which penetrate into the insulated container as a result of unavoidable leakages. The invention provides for the getter material to be accommodated in maintenance areas (20), which can be disconnected by means of valves (21) from the working area (18) which contains the application (12). This allows the getter materials (26) in each maintenance area to be replaced or regenerated, while the operation of the application (12) to be cooled can be maintained owing to the partitioning of the working area (18) from the maintenance area (20).

A method involves sheathing a superconductor with a thermoplastic insulation material on all sides. The conductor exits a guide channel that extends in the propulsion direction. A melt hose is extruded from the molten insulation material in the propulsion direction and through a nozzle that has an outlet which embraces the conductor, whereby a distance is kept on all sides. The melt hose is stretched via the propulsion of the conductor. The hose is drawn to the surface of the conductor and is compacted by cooling. The method can especially be used for sheathing band-shaped high-Tc-superconductors. Materials having processing temperatures between 200° C. and 450° C., are selected as thermoplastic insulation materials.

A super conductor is disclosed, in particular a high temperature super conductor of a synchronous machine, including a cooling circuit for a coolant. The liquefied coolant in the cold head provided with a condenser is guided to the super conductor which is to be cooled, in particular in the rotor of the synchronous machine and is returned to the condenser in a gaseous form. In order to guide the coolant from the condenser to the super conductor, pressure generated by a component of the coolant evaporated by a heat source is used.

A rotor for an electric machine includes a pole core having a coolable magnetisable rotor section which is made of a super-conducting material. The rotor section has a rotationally symmetric geometry. The pole core is formed as a cylinder and the rotor section is arranged on an outer surface of the cylinder so as to be encircling.

A superconductive synchronous machine having superconductive magnetic bearings. A superconductor (6) on the stator side as a first bearing part is disposed opposite from a second bearing part (12) on the rotor side, the second being part being magnetically and mechanically connected via a flux feed section (11) to the pole core (9) of the rotor. A superconductive exciting coil (10) in the rotor pole core (9) excites both the pole core (9) and the second bearing part (12). In order to cool the superconductive exciting coil (10), coolant feeds (16, 16′, 24, 25) are provided, which are sealed in relation to the rotor shaft (8, 8′) by ferrofluid seals (26). The power for the exciting coil is fed via slip rings (21) or by being inductively connected (29) at the rotor shaft (8′).
