An active magnetic rotor-bearing assembly for conveying a fluid comprising a rotor assembly is disclosed and a bearing assembly for contactless bearing the rotor assembly, where the bearing assembly comprises an even number of electromagnetic units arranged around a central structure each comprising a first salient established by a magnetic material and a permanent magnet providing a first magnetic pole and a coil around the salient, further comprises an inter-yoke with inter-yoke portions connected to the first salient of each electromagnetic unit and being separated from each other by structure spacers, providing a closed first magnetic flux passing the rotor assembly applying a first attractive force further comprising a position stabilizing portion perpendicular to the first attractive force on the rotor-assembly and the coils providing an electromagnetic flux between each first salient and the rotor assembly for applying adaptable axial force and/or tilting torque to the rotor assembly.
