Detection of Arcing in DC Motors - ScienceDirect

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. The proposed method utilises system-identification and ...
