The invention provides a fault determination method and device for a rotating machine and electronic equipment, and the method comprises the steps: carrying out the signal decomposition of a vibration signal according to a local feature scale decomposition algorithm, and determining a plurality of intrinsic scale component signals corresponding to the vibration signals in different vibration directions; carrying out vector spectrum information fusion on the optimal intrinsic scale component signals corresponding to different vibration directions, and determining a vector intrinsic scale component signal corresponding to the rotating machine to be detected; and performing envelope spectrum analysis on the full-vector intrinsic scale component signal to obtain bearing fault feature information of the to-be-detected rotating machine, and determining whether the to-be-detected rotating machine has a fault based on the bearing fault feature information. According to the invention, screening of the plurality of int
