Rezumat: Rezolverul este folosit pentru comanda motoarelor electrice fara perii. Avantajul rezolverului este ca acesta furnizeaza in permanenta o marime corespunzatoare pozitiei unghiulare a rotorului, inconvenientul constand in faptul ca furnizeaza o marime analogica si care depinde de o functie trigonometrica. Pentru a obtine informatia de pozitie sub forma digitala, s-au conceput convertoarele rezolver–digital.
Cuvinte cheie: pozitie, rezolver, convertor rezolver-digital
Abstract: The resolver is used to command the brushless electrical motors. The advantage of resolver is the providing of a magnitude corresponding to the rotor angular position. Its drawback consists of analogical magnitude provided, magnitude that depends on a trigonometric function. Resolver-to-digital converters (RDC) were realized in order to obtain the position information in digital mode.
