Abstract

A superconducting machine for supporting a coolant feed line for superconducting machines includes a hollow shaft that can be connected to the superconducting machine in a first region, the coolant feed line being disposed in the interior thereof for feeding the coolant from the refrigeration unit to the superconducting machine. A magnetic support is disposed in the first region of the hollow shaft so that a radial and thus motion-damping, centering force is exerted on the coolant feed line. The magnetic support has a first and a second magnetic cylinder, wherein the first magnetic cylinder is disposed on the outer jacket of the coolant feed line and the second magnetic cylinder is disposed on the inner face of the hollow shaft. The first magnetic cylinder is a cylinder made of highly electrically conductive material having ohmic resistance.
