Technical Electrodynamics| Zusammenfassung: | The mathematical models for definition of the forces operated on the stator winding cores a powerful turbogenerator is presented. On the basis of the developed models are investigated electromagnetic forces on crowns of a teeth and electrodynamics forces which operate in a slot on the conductors of one and different phase windings by means of analytical and numerical calculation methods. The amplitude of the forces operating in a slot with cores of one phase winding more in 1,33 times, than in slots with cores of dissimilar phases are shown. The results of experimental researches of vibrations of the stator core of physical model are presented. In a spectrum of a signal amplitude of the basic harmonic of a magnetic field opposite to a tooth more than opposite to a groove is shown. Since the basic frequency electromagnetic forces is equal 1000 Hz, vibrations on other frequencies are indicate in presence of deflections from a normal technical condition of stator elements.
