Abstract:Motor current stator analysis (MCSA) are usually used to detect the broken bars. In several industrial applications, like cement industry, the motor is subjected to load torque variations of low frequencies, which have effects similar to rotor faults in the current spectrum and result of diagnostic procedure may be ambigues. In this paper, we present a study based on the application of the instantaneous active and reactive courant signature analyses for discriminating broken rotor bars from mechanical load osc… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
