Abstract

A method for determining the characteristic feature quantity of a three-phase induction motor (12) which is required to calculate a deterioration parameter used when diagnosing a rotary mechanical system (10) using the three-phase induction motor (12) as a drive source includes a first process of performing frequency analysis of a current signal in operation from a three-phase induction motor (12), a second process of detecting, by frequency analysis, sideband waves SA and SB of a power supply frequency spectrum SL as the center which respectively exist in a frequency domain A on the low frequency side and a frequency domain B on the high frequency side, and a third process of setting, as an actual rotation frequency fr of the three-phase induction motor (12), the absolute value of the difference between a power supply frequency fline and the peak position frequency of one of the sideband waves SA and SB, thereby setting the actual rotation frequency fr as the first characteristic feature quantity.
