The invention discloses a fault diagnosis method, device and system for an electric vehicle driving motor, relates to the technical field of motor diagnosis, and mainly aims to reduce consumption of vehicle end computing resources and improve the efficiency of motor fault diagnosis. According to the main technical scheme, the method comprises the steps of receiving stator current data corresponding to a permanent magnet synchronous motor sent by a vehicle end; the stator current data are input into a trained multi-classification fault diagnosis model, a diagnosis result corresponding to the permanent magnet synchronous motor is obtained, the multi-classification fault diagnosis model is a 1D convolutional neural network model, and the diagnosis result comprises the occurrence probability corresponding to each fault category; determining a fault result corresponding to the permanent magnet synchronous motor according to the occurrence probability corresponding to each fault category; and synchronizing the fault result to the vehicle end, so that the vehicle end triggers a corresponding early warning operation. The method is used for fault diagnosis of the permanent magnet synchronous motor.
