Embodiment Construction

[0025] figure 1 The basic structure of superconducting electric machine 100 with cooling unit 200 , already described at the beginning with reference to the prior art, is shown again. The electric machine, in this example the synchronous electric machine 100 , is connected to the cooling unit 200 via the device 300 , in particular the hollow shaft 320 and the coolant supply line 310 . In the cooling unit, the coolant is cooled to 77K and fed to the rotor shaft 110 of the synchronous machine 100 via the coolant supply line 310 . In order to avoid heat leakage at the synchronous machine 100 , the hollow shaft 320 is correspondingly long. The hollow shaft is fixedly connected to the rotor shaft 110 on one side, that is to say in the region 320 ″, so that it rotates at the same rotational speed as the rotor 110 during operation of the synchronous machine. A coolant supply line 310 is arranged in the hollow shaft 320 . At the end of the hollow shaft 320 facing away from the sync...

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.

Description

technical field [0001] The invention relates to a device and a method for supporting a coolant supply line for a superconducting electrical machine. The invention relates in particular to a device for supporting long coolant supply lines for superconducting electric motors according to the preamble of claim 1 . A device of this type according to the preamble is known from DE 10358341 A1. Background technique [0002] Since the discovery of high-temperature superconductivity in materials that exert their superconducting role at an operating temperature of 77K (for example, YBCO and BiSCO), superconducting motors with superconducting rotor windings, such as synchronous motors, can be economically advantageously used or a generator. Such a superconducting motor is known, for example, from DE 10358341 A1. [0003] figure 1 A possible configuration of such a superconducting electric machine 100 with an attached cooling unit 200 is shown. Superconducting electric machine 100 ...
