The invention relates to a method for determining current eccentricity of rotating rotor (1) at which is rotor (1) equipped with a phase marker (5) scanned at constant speed of rotation up to 500 rpm by a sensor (50) of phase marker (5) at the point of the phase 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), is from them estimated current position of phasor of the 1st 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 1st 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). Further on, is the invention related to a method of diagnostics of eccentricity of rotating rotor (1) based on this method for determining current eccentricity. |
