The dynamic diagnostic model of the mount of the winding in slot of the stator core of a powerful turbo-generator is constructed. The range of possible values of parameters of model is defined. Dynamics of the symmetric distributed vibro-impact system "winding - core" for various values of system parameters and external exciting forces is studied. Tendencies of change of parameters of the signal of shocking forces with development of defect are defined. Calculation of the spectra of signals of shocking forces that excite the vibroacoustic vibrations of the stator design is carried out.
