WebSep 8, 2024 · Non-uniform air-gap is termed as eccentricity. Eccentricity fault occurs due to bad manufacturing, unbalanced rotor shaft, and bearing wear. Vibration and harmonics in current signal are caused due to eccentricity fault. Increase in eccentricity index leads to rotor-stator collision which leads to mechanical stress. WebConclusion: Two novel measures, poststress change in shape index and eccentricity index, were independently associated with MACE and improved risk estimation. Changes in ventricular morphology have important prognostic utility and should be included in patient risk estimation after SPECT myocardial perfusion imaging.
