| Abstract: | This paper develops a general method for calculating frequency spectrum of radial
electromagnetic vibration of the stator in induction machine with winding deterioration
and unfaulted conditions.The effects of various kinds of magnetic field harmonics in the air
gap are considered in this method.The method is used to obtain a relative comparison of
stator 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. |
