Fluid pump

A method for manufacturing a fluid pump, having the following steps:

• manufacturing a combination rotor as a pump rotor and an electric motor rotor of a disk design with axial arrangement of magnets or soft-magnetic elements in the combination rotor;
• wherein a first stator of an axial flux electric motor surrounds the combination rotor on a first end side, and a second stator of the axial flux electric motor surrounds the combination rotor on a second end side, opposite the first end side, of a common housing;
• wherein a first set of cores of the first stator and a second set of cores of the second stator lie opposite one another, offset in a circumferential direction with respect to one another and axis-parallel with respect to a rotational axis of the combination rotor and wherein such offset results in the cores being non-coaxial among the first and second sets,
• insertion of the combination rotor into an outer ring,
• insertion of a shaft or axle,
• lateral attachment of at least one side wall to the outer ring to provide fluid-tight sealing of the combination rotor accommodating an end of the shaft or axle in the at least one side wall,
• lateral attachment of at least one of the first or second stator of the axial flux electric motor to the at least one side wall in order to drive the combination rotor in the common housing by at least the outer ring and the at least one side wall, wherein the cores of the first and second stator are arranged axis-parallel with respect to the rotational axis of the combination rotor.
