Patent ID: 7061147

Claim:
A plurality of electrical machines based on superconducting technology, each of the machines, comprising: a rotor with superconductors; a rotor cryostat; a rotor shaft; a cryogenic connection to a cryogenic conductor between the cryostat and a cold generator, the cryogenic connection including a fixed cold head and a distributor, projecting into the rotor shaft area, for a liquid coolant; and a non-superconducting stator, wherein the plurality of electrical machines are designed to be shock-resistant, wherein the stator, the rotor and the cryostat are decoupled via elastic elements, in terms of movement, from an outer machine housing and from the rotor shaft, wherein the rotor, stator and cryostat include connecting elements and bearings between them, the connecting elements and bearings resulting in movement of the rotor, stator and cryostat as a unit when accelerated by shock, the movement of the unit being greater than a vibration amplitude, and wherein a flexible cryogenic line is arranged between the distributor for the liquid coolant and the cryostat.
