This thesis addresses the diagnosis of the mechanical faults of the electromechanical machines by treatment of the power supply (currents and voltages). The main aim is to extract and separate the various components, electric or mechanical, which exist. By modeling the asynchronous machine and the bearing defect, we try to explain the impact of the fault, characterized as cyclostationary process, on the operating mode of the machine. The signal processing tools dedicated to the cyclostationary process can bring a new solutions. We propose to combine these tools and the traditional approaches to extract a useful information from a noisy signal or to extract the mechanical informations form the electric signals and vice versa. To validate the...
