A failure symptom detection device for an electric motor-provided equipment, which detects a failure symptom of the electric motor-provided equipment including a load with an electric motor used as a motive-power source and a driving device which supplies power to the electric motor and drives the electric motor, the failure symptom detection device comprising: - a current detection unit which detects current flowing from the driving device to the electric motor; - a diagnosis calculation unit which calculates an index value for determination for presence/absence of abnormality of the electric motor-provided equipment, on the basis of a result of detection by the current detection unit; - a diagnosis determination unit which determines presence/absence of abnormality of the electric motor-provided equipment on the basis of a result of calculation by the diagnosis calculation unit; and - a diagnosis result reporting unit which reports a result of diagnosis determined by the diagnosis determination unit, to outside, characterised in that the diagnosis calculation unit includes - a starting current extraction unit which, from the current detected by the current detection unit, extracts current in an acceleration period until a constant rotational speed is reached after starting of the electric motor, - a data generation unit which divides data of the current in the acceleration period extracted by the starting current extraction unit, into plural pieces of data, and - a frequency analysis unit which performs frequency analysis on each piece of data divided by the data generation unit. the failure symptom detection device comprising: - a current detection unit which detects current flowing from the driving device to the electric motor; - a diagnosis calculation unit which calculates an index value for determination for presence/absence of abnormality of the electric motor-provided equipment, on the basis of a result of detection by the current detection unit; - a diagnosis determination unit which determines presence/absence of abnormality of the electric motor-provided equipment on the basis of a result of calculation by the diagnosis calculation unit; and - a diagnosis result reporting unit which reports a result of diagnosis determined by the diagnosis determination unit, to outside, - a current detection unit which detects current flowing from the driving device to the electric motor; - a diagnosis calculation unit which calculates an index value for determination for presence/absence of abnormality of the electric motor-provided equipment, on the basis of a result of detection by the current detection unit; - a diagnosis determination unit which determines presence/absence of abnormality of the electric motor-provided equipment on the basis of a result of calculation by the diagnosis calculation unit; and - a diagnosis result reporting unit which reports a result of diagnosis determined by the diagnosis determination unit, to outside, characterised in that the diagnosis calculation unit includes - a starting current extraction unit which, from the current detected by the current detection unit, extracts current in an acceleration period until a constant rotational speed is reached after starting of the electric motor, - a data generation unit which divides data of the current in the acceleration period extracted by the starting current extraction unit, into plural pieces of data, and - a frequency analysis unit which performs frequency analysis on each piece of data divided by the data generation unit. - a starting current extraction unit which, from the current detected by the current detection unit, extracts current in an acceleration period until a constant rotational speed is reached after starting of the electric motor, - a data generation unit which divides data of the current in the acceleration period extracted by the starting current extraction unit, into plural pieces of data, and - a frequency analysis unit which performs frequency analysis on each piece of data divided by the data generation unit.
