Abstract
V delu je predstavljena celotna veriga določitve izgub v železu sinhronskega stroja s trajnimi magneti, v procesu analize z metodo končnih elementov. S pomočjo simulacije sinhronskega stroja so identificirani posamezni pojavi, ki bi lahko vplivali na vrednost izgubne moči ter natančnost določitve posameznih modelov za določitev izgub v železu. Fenomeni so podrobneje preučeni s pomočjo vzorcev elektro pločevine ter primerjani z Bertottijevim ter LS modelom. S pomočjo opravljenih meritev so pridobljeni potrebni koeficienti ter dokazana funkcionalnost modelov. Opravljena je bila tudi implementacija modelov v proces analize rotacijskih strojev s pomočjo programskega paketa FEMM v povezavi z okoljem Matlab. Podrobna analiza ter meritve magnetih dogajanj so omogočile dober vpogled v mehanizem izgub v železu, ki lahko olajša načrtovanje elektromagnetnih komponent.

Title:
Identification of influential phenomena on iron losses in permanent magnet synchronous machine
Abstract:
Thesis presents the entire chain of iron losses prediction in case of permanent magnet synchronous machine in the analysis process using finite element method. Through simulation of synchronous machine the individual phenomena that could affect the value of the power loss and accuracy of iron loss models is identified. Phenomena are further examined using samples of electrical steel sheets and compared with Bertotti and LS models. With the help of measurements the necessary coefficients are obtained and functionality of the models is demonstrated. Iron loss models are implemented in the simulation process using FEMM software in connection with the Matlab environment. Detailed analysis and measurements of magnetic behavior allow a good insight into the mechanism of ferromagnetic losses, which may facilitate in the design of electromagnetic components.
