Abstract
U ovom radu, opisan je utjecaj skošenja utora rotora (štapova) asinkronog motora na njegov rad pod nazivnim opterećenjem. Skošenje utora rotora u teoriji prigušuje neželjene parazitne harmonike magnetske indukcije, vibracije i buku te je bilo potrebno simulacijom doći do rezultata koji će potvrditi tu teoriju ili doći do suprotnih rezultata, uz objašnjenje istih. Obavljene su simulacije nekoliko modela kaveznog motora, bez i sa skošenjima različitih iznosa. Geometrija modela je napravljena u alatu RMxprt, a simulacija je napravljena u Maxwell 2D pomoću metode konačnih elemenata. Rezultati su obrađeni Fourierovom transformacijom i spektralnom analizom. Analizom momenta se dolazi do zaključka kako su skošenjem prigušeni parazitni momenti, a time i buka, dok neki neželjeni harmonici indukcije, zbog razlike između stvarnog motora i modela, ostaju prisutni.
Abstract (english)
This master thesis describes the influence skewed rotor slots (bars) of the induction machine has on its operation under nominal load. Skewed rotor slots, in theory, suppresses unwanted parasitic flux density harmonics, vibrations, noise and it was necessary, by simulation, to come up with results that would corroborate that theory or come to the opposite results, with an explanation of the same. Simulations of several models of squirrel-cage induction machines have been made, without and with the skewing of different amounts. The geometry of the model was made in RMxprt tool, and the simulation was made in Maxwell 2D using the finite element method. The results were processed by Fourier transform and spectral analysis. By analyzing the torque, it comes to the conclusion that the parasitic moments and thus the noise are suppressed by skewing, while some unwanted flux density harmonics, due to the difference between the actual engine and the model, remain present.
