Ideal condition of a synchronous machine and subsequent fault models representing rotor eccentricity of different types as well as inter-turn short circuits in stator and rotor are created with finite element method simulation for a specially designed SM. This machine has provisions of recreating the same faults made in the simulations by suitable changeover of customized end-shields and sleeves in...
W pracy przedstawiono wyniki badań diagnostycznych silnika indukcyjnego przy wykorzystaniu sygnałów prądów fazowych w niestacjonarnych stanach pracy spowodowanych skokowymi zmianami momentu obciążenia. Zastosowano metodę analizy opartą na wykorzystaniu transformaty falkowej. Zbiory falkowych funkcji bazowych użytych w testach diagnostycznych zbudowano w oparciu o rzeczywiste przebiegi prądów fazowych...
The rapid growth of the signal processing theory resulted in the rise of new methods in diagnostics of the drives. This paper focuses on the application of the complete systems of orthogonal functions, for which fast computational procedures are applicable. It is shown that a spectral analysis employing bases of the Haar functions is highly suitable for both analysis and synthesis of the diagnostic...
