Abstract:
1. A rotational machine adapted as a bearing-free engine including a stator designed as a bearing and drive stator having a magnetic stator plane and a magnetic rotor having a magnetic rotor plane and supported magnetically in contact free manner within the stator, wherein an axial height of the rotor is smaller than or equal to a half diameter of the rotor and the rotor is stabilized passively by reluctance forces with respect to the magnetic stator plane both against an axial displacement and also against a tilting from an equilibrium position and a sensor unit having a first sensor and a second sensor is provided at the stator such that for the determination of a deflection of the rotor from the equilibrium position a first sensor signal from a first measurement zone of the rotor can be evaluated by means of the first sensor and a second sensor signal from a second measurement zone can be evaluated by means of the second sensor, characterized in that for the determination of the tilting of the rotor relative to the magnetic stator plane a first control measurement zone which is part of the first measurement zone is provided either below or above the magnetic rotor plane at the rotor such that at least 50% of the first sensor signal which can be generated from the first measurement zone can be generated by the first control measurement zone at the first sensor, wherein the tilting of the rotor brings about a damping force on a tilting movement of the rotor via a differentiating portion of a radial position regulator.
