Abstract

U ovom radu napravljene su simulacije asinkronog motora modeliranog u programskom paketu Infolytica MagNet. Također, napravljena je MATLAB skripta kojoj je svrha automatizirano pokretanje simulacija. Simulacije su provedene na dva načina. Prvo su napravljene simulacije kojima se željeno stanje stroja postiglo napajanjem stroja kliznom frekvencijom, dok se drugim načinom postiglo mijenjanjem vodljivosti materijala rotora. Rezultati simulacija korišteni su kako bi se prikazala ovisnost pojedinih parametara stroja o struji statora i klizanju. Oba načina dala su očekivane ovisnosti. Cilj rada je bio napraviti algoritam za minimizaciju struje statora modeliranog asinkronog stroja za definirani elektromotorni pogon.

Abstract (english)

MagNet, have been made. Also, MATLAB script has been made to automatically run those simulations. Simulations have been made in two ways to achieve desired machine state. One way was to apply slip frequency to the stator of the machine, and the other was to change the conductivity of the rotor material. The results of those simulations were used to show the dependance of certain parameters of the machine on the stator current and slip. Both ways gave the expected results. The purpose of the thesis was to create an algorithm for minimisation of the stator current for the a priori defined electric drive.
