On-line identification of three-phase motor running state can be realized by using the theory of e-lectrical signal fusion. By using a three-phase electrical signals of the principal component analysis algo-rithm, which improves the speed of the data fusion and on-line identification, the requirements of the real-time observation has been reached. Designed a running condition recognition software based on LabVIEW and PCA algorithm, with the help of the extraction, fusion, analysis, storage electrical signals in the motor, which implements the feature recognition for the running status. At last, the reliability and practicability of this technology is verified by the experiments.
