Fecha de publicación: 29/12/2022 Fuente: WIPO (eseential oils OR extracts) This failure symptom detection device for electric motor-provided equipment comprises: a diagnostic calculation unit (91) that calculates an index value for determining whether there is an abnormality in electric motor-provided equipment (1) on the basis of the detection result of current flowing from a drive device (4) to an electric motor (3); and a diagnostic determination unit (92) that determines whether there is an abnormality in the electric motor-provided equipment (1) on the basis of the calculation result of the diagnostic calculation unit (91). The diagnostic calculation unit (91) is provided with: a starting current extraction unit (911) that extracts, from the detected current, a current during an acceleration period from the time of starting the electric motor (3) to the time of reaching a fixed rotational speed; a data generation unit (914) that divides, for data on the current having been extracted by the starting current extraction unit (911), data within the acceleration period into a plurality of data items; and a frequency analysis unit that performs frequency analysis on each of the data items acquired through the division carried out by the data generation unit (914).
