Popis: Blind signal separation technique is the new one for array processing and data analysis. The research object of the paper is the complex and aliasing vibration signal measured from the AC electric motor velocity modulation system. Fast ICA algorithm is adapted to separate the vibration signals. Major source signals have been successfully and clearly separated from the complex and aliasing measured vibration signals. Then the characteristics of each source vibration signals can be effectively extracted in different frequency by analyzing source signals. The results are helpful for the later data analysis.
