WebOct 12, 2024 · Eccentricity fault in electrical motor causes increased noise and vibration, and degradation of motor characteristics. Thus, early detection of the eccentricity fault is required. Motor current signal analysis, a common fault detection method, may fail to detect eccentricity faults, depending on the type of eccentricity. This article proposes an … WebTo add to the fun, the three effects I've listed—changes in eccentricity, changes in obliquity, and precession—are not independent. According to Berger, cycles in eccentricity arise from 'beats' between different precession cycles: The 95,000-year eccentricity cycle arises from a beat between the 23,700-year and 19,000-year precession cycles.
