Abstract
The invention relates to a rotary machine comprising a stator and a rotatably mounted rotor, with one or more magnetic field sensors arranged stationary relative to the stator at a radial distance from a stationary axis, at least one measuring device which configured to detect magnetic field changes with the aid of the aforementioned magnetic field sensors, a rotor which is configured to generate one or more electrical signals in each case, said signals having signal components which correspond to the rotor rotation frequency and to the distance between magnetic field sensor and rotor in each case, wherein a demodulator unit carries out a demodulation of signals generated by or derived from the magnetic field sensors, such that a signal is generated which corresponds to the distance between the rotor and the magnetic field sensor.
