Optimizacija univerzalnega motorja

MRLJAK, LUKA (author), Miljavec, Damijan (mentor)

V diplomskem delu je predstavljeno 3D-modeliranje univerzalnega elektromotorja s pomočjo metode končnih elementov. Vezni model elektromotorja je izdelan v simulacijskem okolju Cedrat Flux. V prvem delu je izdelan model serijsko proizvajanega elektromotorja, ki mu v drugem delu optimiziramo končni izkoristek in znižamo stroške materiala, potrebnega za njegovo izdelavo. Del diplomskega dela je posvečen klasifikaciji in načinu izračuna izgub v železnem jedru ter optimizaciji izgub v bakrenem navitju. Rezultat diplome je prototip optimiziranega univerzalnega motorja. S pomočjo njegovih meritev je narejena primerjava med matematičnem modelom in realnim prototipom.

Abstract

The thesis describes the 3D modeling of an universal electrical motor based on finite element analysis. The motor is modeled in Cedrat Flux environment. The thesis also describes the commutation motor modeling techniques and modeling of a real motor which is optimized in the second part of the thesis. A part of the thesis is dedicated to the classification and computation of the iron core losses and optimization of copper winding losses in the analyzed motor. The result of this research is the optimized universal electrical motor in a form of prototype. On the basis of the measurements the comparison between the prototype and mathematical model is made.
