Embodiment Construction

[0012] The electrical machine arrangement 1 shown in the figure has an electrical machine 2 and a cooling system. The electric machine is, for example, a synchronous electric motor or a generator, comprising a rotor 3 with a superconducting winding, in the figure only the rotor shaft 4 and its terminal section 5a protruding from the end walls 6a, 6b of the machine housing 7 , 5b is visible. The basic construction of electric machines with superconducting windings is known from the documents mentioned at the outset, to which reference is expressly made here. Arranged on the end wall 6 a is a circular link body 8 , wherein the link body is formed, for example, by a ball bearing or a roller bearing. A further link body 8 is fastened to a bracket 9 positioned at a distance from the end wall 6a, wherein this link body can likewise be designed as a rolling or ball bearing. The link body 8 is arranged coaxially to the axis of rotation 10 of the rotor 3 and serves to support a carri...

Abstract

A superconducting machine device is disclosed including a machine; a rotor including a superconductive coil; and a cooling system including at least one incline-intolerant component for cooling the coil. In at least one embodiment, at least one component is held by a carrier compensating for an incline of the machine device.

Description

technical field [0001] The invention relates to an electric machine comprising an electric machine with a superconducting rotor winding and a cooling system for cooling the rotor winding or the rotor. Background technique [0002] Cooling systems of such devices as are known, for example, from DE 100 57 664 A1, DE 103 21 463 A1 and DE 100 39 964 A1 usually have parts that do not allow tilting, which is problematic when used on ships or offshore platforms. For oil-lubricated compressors, for example, it is necessary that the suction area of ​​the lubrication circuit is always arranged inside the oil sump or oil pan. In extreme inclination situations there is therefore sometimes a fear of an interruption of the lubrication with the resulting negative consequences. Furthermore, there is a risk that the compressed working gas will become contaminated with oil, since oil separators and adsorbers are designed for vertical operation. Superconducting windings are mostly cooled by ...
