In the article numerical calculation results of natural frequencies for end-winding of synchronous of generator stator are presented. The numerical model was draw up using the finite element methods. This calculations allow for designing the end-winding out of work scope in the resonance and for extending the of electric machines life.
Duże siły i amplitudy drgań występujące w pobliżu lub stanie rezonansu są niebezpieczne dla maszyn elektrycznych. Naprężenia dynamiczne towarzyszące drganiom przy częstotliwościach rezonansowych prowadzą do zniszczenia zmęczeniowego. Dlatego maszyna elektryczna powinna być tak zaprojektowana, aby uniknąć pracy w pobliżu rezonansu, a więc jej częstotliwości drgań własnych powinny znajdować się w bezpiecznej...
