A new method to analyze the vibration signal of the asynchronous motor based on chaos theory and fractal geometry was proposed.The frequency and the Lyapunov index showed that the vibration signal has obvious chaotic features.Then reconstructed the data sequences' phase space.Used the classical algorithms to find the delay time and the embedding dimension of the system.Finally,calculated the correlation dimension of the reconstructed strange attractor.This method provides the basis for fault analysis of the eccentric motor.
