Notice of Violation of IEEE Publication Principles Bearing Damage Detection of the Induction Motors using Current Analysis

This paper deals with the application of CSA for detection of bearing damage on induction motor. Three-phase IM are the "workhorses" of industry and are the most widely used electrical machines. In industrialized nations, 70% of industrial processes use the induction motor. For this reason, detection of incipient motor failures is very important, thereby avoiding production lost and reducing operational costs. The main idea of motor damage detection leads with "motor variables, currents, flux, electric torque and power, variations (in particular the spectrum) with respect to the normal time-varying operating conditions of the motor". MCSA is a noninvasive on line monitoring technique to diagnose faults in three-phase IM by differences detection between fault and normal conditions, in current spectrum. Experimental tests were realized in IM of small power, and the results will be validated in later works with a representative quantity of motors.
