The invention relates to the technical field of motor fault detection, and relates to a driving motor fault detection method and device, computer equipment and a storage medium. The method comprises the following steps: respectively acquiring a reference spectrum and a spectrum deviation range of a part sample of a driving motor; acquiring a first vibration signal and a first rotating speed signal of at least one real part of the driving motor in the bench experiment process of the driving motor; according to the first vibration signal and the first rotating speed signal, obtaining a frequency spectrum of the part object; respectively acquiring a spectrum difference between the spectrum of the at least one part object and the corresponding reference spectrum; if the frequency spectrum difference exceeds the frequency spectrum deviation range, taking the frequency spectrum of the corresponding part object as the target frequency spectrum of the corresponding part; accumulating the at least one target frequency
