Abstract: A magnetic levitation includes a stator with coil cores, a concentrated winding provided at each longitudinal leg of the coil cores surrounding a respective longitudinal leg, the stator including a cup-shaped recess into which a rotor is configured to be inserted, magnetic field sensors to determine the position of the rotor arranged around the cup-shaped recess, and a ring-shaped holding device for the magnetic field sensors, the ring-shaped holding device having a cavity for each magnetic field sensor, the cavity delimited with respect to the radial direction by an inside wall and by an outside wall. The magnetic field sensors to be pushed into the cavity, and the cavity dimensioned such that the inside wall and the outside wall rest flat against the magnetic field sensors.

Abstract: A magnetic levitation device includes a housing, a stator and a controller. The stator includes coil cores having longitudinal and transverse legs and a winding at each longitudinal leg. The stator has a recess for the rotor. The controller includes a circuit board with front and back sides, with circuit breakers arranged on the front side. The housing includes an outer wall, a stator housing, a control housing, and a separating wall separating the stator housing from the control housing. A web is arranged on the separating wall adjacent to the outer wall, projecting into the control housing. The back side of the circuit board is supported on the web. The circuit breakers are arranged in an area with which the back side of the circuit board is supported on the web. The thermal connecting elements for dissipating heat are between the plurality of circuit breakers and the web.
