Abstract

The invention relates to the technical field of fault diagnosis, in particular to a motor fault diagnosis method and device, a storage medium and electronic equipment, and solves the problem that a fault diagnosis result is inaccurate due to the adoption of single-domain feature extraction in related technologies. The method comprises the following steps: collecting a vibration signal of a to-be-tested motor; sampling the vibration signal to obtain a vibration signal sample set; extracting vibration features in the vibration signal sample set to obtain a vibration feature sample set, wherein the vibration features comprise a time domain feature, a frequency domain feature and a time frequency feature; and inputting the vibration characteristic sample set into a pre-trained diagnosis model to obtain a diagnosis result. According to the invention, fault diagnosis is carried out in a mode of extracting the multi-domain features, the performance degradation degree of the motor equipment can be accurately described, and an accurate fault diagnosis result can be efficiently obtained.

Description

technical field [0001] The present application relates to the technical field of fault diagnosis, in particular to a motor fault diagnosis method, device, storage medium and electronic equipment. Background technique [0002] With the continuous development of my country's social economy and the continuous improvement of people's living standards, various household appliances continue to enter people's lives, bringing people great convenience. However, as people's demand for electrical equipment continues to grow, while bringing huge business opportunities to electrical equipment, it also puts forward higher requirements for ensuring the normal operation of electrical equipment. For example, for electrical equipment including motors, due to the inevitable aging and wear of the motors, the performance of the electrical equipment will deteriorate or even lose its working ability. When electrical equipment fails, the traditional manual troubleshooting method requires experts t...
