Abstract
A first radial bearing includes nozzles in the stator at a radius rand a bearing surface on a circular section of the rotor at a radius R. A second radial bearing includes nozzles in the stator at a radius rand a bearing surface on the rotor at a radius R. An axial bearing includes a nozzle in the stator and a bearing surface on an axial end of the rotor, which runs orthogonally to the rotation axis and has an outer radius R. The second radial bearing is formed on an end section of the rotor, which has a smaller radius than or a radius that decreases away from the circular section, so that R<Rand r<r. The third bearing surface is formed on an end of the end section facing away from the circular section, so that R≤R
