Abstract

V magistrskem delu je prikazana odvisnost izgub elektromehanskega pogona, sestavljenega iz trifaznega asinhronskega motorja in frekvenčnega pretvornika, od parametrov nadomestnega vezja motorja in posledično izbranih parametrov regulatorjev. Izračun parametrov nadomestnega vezja trifaznega asinhronskega stroja je izveden s pomočjo standarda [1], s pomočjo iterativnega izračuna parametrov ter z analitičnim izračunom s programskim orodjem emLook. Merilni del je izveden s standardom [19]. Standard predpisuje določitev izgub in izkoristka pogonskega sklopa glede na različne parametre nadomestnega vezja. Delo je sklenjeno z analizo in opisom rezultatov ter razlago rezultatov.

Secondary title: Influence of parameters on power losses of three-phase unduction motor powered by frequency inverter
Secondary abstract: The aim of master's thesis is to present the power losses of three-phase induction motor powered by frequency inverter, dependent on differently entered parameters of equivalent circuit of induction motor and consequently the selected parameters of regulators. Three-phase induction motor equivalent circuit parameters calculation is performed by using standard [1], iterative calculation parameters and analytical calculation using the emLook software tool. The measuring part is presented by the standard [19], where we determine the losses and the efficiency of the power drive, depending on the different entered parameters of the equivalent circuit. The work is concluded by analysis and describing the results, and the reasons why the results obtained are as they are.
