Abstract
A simple diagnostic of a rotary mechanical system is performed involving: a first step for performing a fast Fourier transform on an operation-time current signal of a three-phase induction motor 12; a second step in which the sidebands of the current spectrum peak of the power frequency, present at frequency positions centered on the current spectrum peak of the power frequency and separated from each other to the lower-frequency side and to the higher-frequency side by a characteristic frequency interval related with abnormalities in the rotary mechanical system 11, are extracted from the obtained current spectrum, and the current spectrum peak value is calculated from one or both sidebands; a third step in which a deterioration parameter of the rotary mechanical system 11 is calculated from the current spectrum peak values of the power source frequency and the sidebands; and a fourth step in which the value of the deterioration parameter is recorded and is compared with a deterioration criterion value to detect abnormalities in the rotary mechanical system 11.
