Abstract
The present disclosure relates to a motor malfunction monitoring device, and a drive motor for oilfield operations including: a signal acquisition module configured to acquire operation data of the drive motor, wherein the signal acquisition module comprises a vibration signal acquisition unit and/or an electrical signal acquisition unit, the vibration signal acquisition unit comprises one or more vibration sensors mounted at a component to be detected of the drive motor during use and provided for detecting transverse vibration and/or longitudinal vibration, and/or the electrical signal acquisition unit comprises a voltage sensor and a current sensor for detecting a voltage and a current of the drive motor, respectively; a data storage module storing therein a database of normal operation spectrums created when the drive motor runs normally; and a signal analysis module configured to extract an acquired operation data spectrum of the operation data acquired, compare the acquired operation data spectrum with a respective normal operation data spectrum in the database of normal operation spectrums to obtain a similarity, and determine that the drive motor fails when the similarity is less than a predetermined threshold.
