Abstract

U ovom radu projektiran je sinkroni reluktantni motor potpomognut permanentnim magnetima za primjenu u pogonu električnog automobila. Na početku je dan pregled načela rada sinkronih reluktantnih motora. Dan je opis oblika rotorskih barijera i funkcije Žukovskog iz koje slijedi takva geometrija barijera. Opisan je postupak parametriranja geometrije motora i odabira parametara koji se optimiraju. Pomoću programskih paketa Comsol čiji proračun se temelji na metodi konačnih elemenata te uz pomoć programskog paketa Matlab napravljena je optimizacija za izvedbe motora dva, tri i četiri sloja barijera na rotoru. Funkcija koja se minimizira optimizacijom je omjer momenta i volumena motora uz poštivanje funkcija ograničenja i provjeru izvedivosti geometrije. U prikazu rezultata optimizacije napravljena je usporedba između tri izvedbe motora.

Abstract (english)

In this thesis, a permanent magnet assisted synchronous reluctance motor for use in an electric car is designed. At the beginin, a review of the working principle of synchronous reluctance motor is given. Later on, a description of the shape of rotor barriers and Zhukovski function, followed by such geometry of the barriers are given. The procedure for parameterizing motor geometry and selection of parameters that are optimized is described. Using the Comsol software package, whose calculation is based on finite element method, and with the help of Matlab software package, motors with two, three and four layers of rotor barriers have been optimized. The function that is minimized by optimization is the ratio of torque and volume of motor, while respecting the constraints and checking the feasibility of the geometry. In the results obtained, a comparison was made between three motor designs.
