1. A blood pump, comprising:
an inlet;
an outlet;
a rotor for delivering fluid from the inlet to the outlet, wherein the rotor is suspended within the blood pump by radial passive magnetic forces to axially attract or repel in one direction at least by way of passive magnetic forces, so that during a fluid-delivering rotation of the rotor, axial thrust of the rotor acts counter to axially acting magnetic forces;
a stator;
a plurality of motor coils included in the stator of the blood pump; and
rotor magnets included in the rotor, wherein the motor coils are arranged on a side of the rotor facing the inlet or on a side of the rotor facing away from the inlet.
