Abstract

Domination of three phase induction motor in industrial drives demands precise and reliable diagnostics for interior fault detections. Electrical, mechanical, thermal, magnetic and environmental stresses during operation might result in internal faults in these machines. Avoiding unscheduled maintenance intervention can prevent immense monetary loss in process industries. Detection of faults in its premature state becomes an indispensable need in all such critical applications. Conventional DQ model of AC machines are not found to be used by researchers for internal fault analysis. Hence possibility of modification in conventional DQ model for static eccentricity analysis was investigated. Motor current signature analysis for static eccentricity condition in induction motor is conducted using proposed extended DQ model. Experimental validation of the results in a three phase squirrel cage induction motor with fabricated static eccentricity is also presented
