- Motor current signature approaches to broken rotor bar detection in motor drives were pioneered 30 years ago. Broken bars are a common cause of motor failure, yet since the first advances there has been only incremental improvement in this approach.
That is, until the publication of this paper, because this provides a step change in sensitivity and automated capability. It’s an important further step towards the objective of monitoring an entire machine from the drive motor. The method is presently part of a large research contract to establish a full scale condition monitoring demonstrator for a world leading ship builder.
