Analiza wpływu wybranych uszkodzeń na pracę napędu z silnikiem PM BLDC w układzie zasilania z zewnętrznym regulatorem napięcia. Badania symulacyjne

The paper presents a simulation test cascade control system of PM BLDC motor speed with subordinated current control loop. Tests had been performed in Matlab/Simulink in the case when an external voltage regulator is a source for electronics commutator. In this case it has the only role of the commutation, according to the name. The work presents the influence of some faults on waveforms of the phase currents, supply motor current and motor speed. To assess the state also proposed hodograph’s analysis of the spatial vector of stator currents and an analysis of spectra current amplitude. Selected results of simulation research have been presented.
