【Abstract】 This paper develops a general method for calculating frequency spectrum of radialelectromagnetic vibration of the stator in induction machine with winding deteriorationand unfaulted conditions.The effects of various kinds of magnetic field harmonics in the airgap are considered in this method.The method is used to obtain a relative comparison ofstator vibration spectrum in a wound-rotor induction machine running under normal con-ditions with those of the same motor when it has experienced internal line-to-line deterio-ration between two stator phases.更多还原
