Abstract
A magnetic bearing with high-temperature superconductor elements which has a stator and a rotor, which is held such that it can rotate with respect to the stator and is mounted in an axially and radially self-regulating manner in the stator. A body of a Type-2 superconductor, in particular a high-temperature superconductor, is provided on the rotor. The stator has a coil of a superconducting material.
Claims9
A magnetic bearing with high-temperature superconductor elements, comprising:
- a stator;
- and
- a rotor which is held such that it can rotate with respect to the stator and k mounted in a self-regulating manner axially and radially in the stator,
- wherein a body comprising a type-2 superconductor is provided on the rotor, the body having a cylindrical outermost surface between two axial ends, and
- wherein the stator has a coil composed of a superconducting material, the coil arranged between the two axial ends and surrounding the cylindrical outermost surface, the coil forming a magnetic field in an area of the body, and
- the body having crystalline defects on which flux vortices of the magnetic field of the coil are retained, whereby the magnetic bearing has the effect of an axial bearing and a radial bearing.
