Finite Element Analysis Study of FBG Magnetostrictive Composite Flux Sensor Geometry for Electric Motor Air-gap Flux Monitoring

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


With the progressively more prominent usage of electric motors in a wide range of applications, more advanced monitoring of their operating parameters is becoming increasingly important. The in-service observation of the air-gap magnetic flux can be very useful for monitoring the status of permanent magnets, which are key to most modern motors’ performance. This was recently shown to be possible through the in-situ application of magnetostrictive composite fibre optic flux sensors. This paper reports an electromagnetic finite element model study exploring the performance of various such sensor configurations and positions in the air-gap of a commercial motor design, with a view to identifying sensor design and implementation features that can yield an enhanced response.
