Design and analysis of Air-Gap Faults in Switched Reluctance Motor

SRM is utilized in many industrial applications owing to its simple construction along with its ruggedness. While this feature is inherently present due to the robustness of SRM, it is not guaranteed a fail-safe and needs in-depth analysis for various operational circumstances. In rotating machines, one of the most general faults is Eccentricity which may lead to operational defects. A few end-users mistook this eccentricity as sloppy alignment, despite the essential need for it to diagnose and assess whether or not the motor’s left/right run-out is running true. This work reports simulations of the proposed model for comprehending SRM operational characteristics at low, medium and high severities under static, dynamic and mixed forms of eccentricity.
