    • 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′).
    • 超导同步电机具有超导磁力轴承。 作为第一轴承部的定子侧的超导体(6)与转子侧的第二轴承部(12)相对配置,第二部分通过焊剂供给部(11)被磁力和机械连接到极 铁心(9)。 转子极芯(9)中的超导激励线圈(10)激励极芯(9)和第二支承部件(12)。 为了冷却超导励磁线圈(10),提供冷却剂供给(16,16',24,25),其通过铁磁流体密封件(26)相对于转子轴(8,8')密封。 励磁线圈的功率通过滑环(21)或在转子轴(8')处被感应连接(29)馈送。
