Dynamic Analysis of the Simultaneous Mixed Eccentricity and Broken Rotor Bars in Induction Machine Based on Magnetic Field Diagnosis

Abstract

Background: Several approaches have been proposed for monitoring and diagnosis of the induction machine. Although, most of them focus on a single fault, but in a real rotator machine, two or more defects can be present simultaneously. Furthermore, one faulty condition could impair the detection of a differing fault and a wrong decision about the operational status of the machine.
