1. A heart support system, comprising:
a rotor bearing system comprising:
a housing, wherein a first permanent magnet is mounted within the housing and configured to rotate about a first axis;
a rotor configured to convey a liquid, wherein the rotor comprises a second permanent magnet, wherein the second permanent magnet comprises a hollow-cylindrical permanent magnet and is configured to rotate about a second axis;
wherein the first permanent magnet and the second permanent magnet at least partially overlap axially,
wherein the first permanent magnet is axially offset relative to the second permanent magnet,
wherein the first permanent magnet and the second permanent magnet are arranged to produce an axial force;
wherein the housing is positioned between the first permanent magnet and the second permanent magnet in an axial overlap region of the first permanent magnet and the second permanent magnet;
a first bearing configured to provide a relative axial positioning of the rotor and the housing with respect to one another and configured to receive the axial force resulting from the arrangement of the first permanent magnet and the second permanent magnet; and
a second bearing, wherein the first bearing and the second bearing are configured to receive radial forces and configured to position the second axis of the second permanent magnet.
