Abstract:V diplomskem delu je obravnavan elektromagnet na izmenični tok s spremenljivo zračno režo med jedrom in kotvo, v območju od 0 mm do 5 mm. Za primera brez in s kratkostičnima obročema na jedru je bila opravljena analiza magnetnih razmer, časovnih potekov električnih veličin vzbujalne tuljave in toka kratkostičnih obročev ter časovnega poteka sile na kotvo pri različnih dimenzijah zračne reže. Omenjene analize so bile izvedene s pomočjo programa OPERA 3D, ki temelji na metodi končnih elementov. Uporabljen je bil harmonični tip izračuna magnetnega polja, kar ustreza stacionarnemu obratovanju elektromagneta. To pomeni, da prehodni pojavi v izračunu niso bili zajeti. Rezultati analiz so prikazani v grafičnih in tabelaričnih oblikah.

Title:ANALYSIS OF MAGNETIC CONDITIONS ELECTROMAGNET WITH SHORTING RINGS
Abstract:In this thesis is diskussed about electromagnet on a alternating current with variable air gap, between the the iron core and armature, in the range of 0 mm to 5 mm. In both cases of electromagnet with and without shorting ring were made analysis of magnetic conditions, timing of a electrical quantities of coil, timing of shorting rings, and timing force of armature on the different dimensions of air gap. Mentioned analysis were made with program OPERA 3D, which is based on method of finite elements. Used was a harmonical type of calculation for magnetic field, which is corresponding to stationary operation electromagnet. This means that transients effecst were not included. Results od analysis are presented in graphic and table form.
Keywords:Electromagnet, shorting ring, magnetic field, finite element method
