A method is provided for producing a bearing arrangement for an implantable blood pump. A bearing arrangement and an implantable blood pump are also provided. In the method, a rotor may be provided having one or more drive magnets. The rotor has a conveying element. In addition, a stator having stator windings is provided. Furthermore, the rotor is arranged in a flow channel formed by an inside wall of the stator. A rotor rotation is then driven. While the rotor rotation is driven, a deflection of the rotor is determined. In addition, the deflection of the rotor may be corrected by applying, removing, magnetizing and/or demagnetizing magnetically active material on the stator and/or on the rotor in a non-rotationally symmetrical manner.
A method for producing a bearing arrangement for an implantable blood pump, comprising:
(canceled)
An implantable blood pump comprising an electric motor including a rotor, a stator, and a bearing arrangement with a passive magnetic radial bearing, the passive magnetic radial bearing comprising at least one rotor bearing magnet and at least one stator bearing magnet, characterized by a magnetically active material applied non-radially symmetrically to the rotor and/or to the stator to define and/or correct a radial deflection of the rotor.
