Magnetic levitation device and a centrifugal pump

A magnetic levitation device for contactless magnetic levitation of a rotor, comprising:

• a disk-shaped or ring-shaped magnetically effective core;
• a stator comprising a plurality of coil cores with a plurality of longitudinal legs and a plurality of transverse legs, each coil core of the plurality of coil cores comprising a longitudinal leg of the plurality of longitudinal legs extending from a first end in an axial direction to a second end, and a transverse leg of the plurality of transverse legs arranged at the second end of the longitudinal leg and extending in a radial direction perpendicular to the axial direction, at least one concentrated winding provided at each longitudinal leg of the plurality of longitudinal legs surrounding the longitudinal leg, the stator further including a cup-shaped recess into which the rotor is capable of being inserted, the cup-shaped recess arranged at an axial end of the stator, and the transverse leg of each of the plurality of transverse legs arranged around the cup-shaped recess;
• a first holding device;
• and
• a second holding device capable of being connected to the first holding device,
• the first holding device comprising a bottom plate on which a plurality of holding elements is provided, each holding element of the plurality of holding elements extending in the axial direction and designed to receive exactly one longitudinal leg of the plurality of longitudinal legs, and the second holding device is configured to receive the plurality of transverse legs.
