Study of Induction Motor Inter-Turn Fault Part I: Development of Fault Models with Distorted Flux Representation

Energies, 2022
An inter-turn fault (ITF) is one of the most frequent induction motor faults; thus, many previous works have studied its model and diagnosis. However, previous works, simplifying the specific distorted flux distribution by the ITF, presented induction ...

Variation-aware fault modeling [PDF]

Science China Information Sciences, 2010
To achieve a high product quality for nano-scale systems both realistic defect mechanisms and process variations must be taken into account. While existing approaches for variation-aware digital testing either restrict themselves to special classes of defects or assume given probability distributions to model variabilities, the proposed approach ...
