Claim:
1. A method for determining current eccentricity of rotating rotor ( 1 ), wherein, the rotor ( 1 ) equipped with a phase marker ( 5 ) is at constant speed of rotation up to 500 rpm scanned by a sensor ( 50 ) of phase marker ( 5 ) at the point of this marker ( 5 ), and outside of the phase marker ( 5 ) by at least one sensor ( 3 , 30 , 4 , 40 ) of relative rotor vibrations, while after digitizing the signals of the sensors ( 3 , 30 , 4 , 40 , 50 ), there is estimated, based on the digitized signals, a current position of phasor of the 1 st harmonic component of signal of the sensor ( 3 , 30 , 4 , 40 ) of relative rotor vibrations in the complex plane, which is subsequently compared to a reference position of the phasor of the 1 st harmonic component of this signal, which has been determined in advance, whereas the variation vector of the phasors is an image of eccentricity of the rotor ( 1 ).
