Detection of arcing in DC motors

open access: yes1999 Information, Decision and Control. Data and Information Fusion Symposium, Signal Processing and Communications Symposium and Decision and Control Symposium. Proceedings (Cat. No.99EX251), 1999
Abstract This paper outlines an on-line condition-monitoring method for detecting arcing around the brush-commutator interface in DC motors. These motors are the critical components in steel-rolling mills, and tend to have excessive arcing and motor flashover under certain circumstances.
