DETECTING STATOR AND ROTOR FAULTS IN A SYNCHRONOUS ELECTRIC MACHINE USING A CURRENT STATOR SIGNATURE
In this paper, the analysis of the stator current signature in the real axes and the analysis of the modulus of the Park current vectors are presented for the diagnosis of stator and rotor faults in an operating three-phase salient pole synchronous motor, directly connected to the network and using the fast Fourier transform. Simulation results are presented to show the effectiveness and merits of these two proposed approaches for fault detection and to discriminate from other abnormal conditions responsible for the same motor behavior.
