Abstract (en)

[origin: WO2008006699A1] 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').
