Izračun elektromagnetnih vibracij sesalne enote z metodo končnih elementov

Čemažar, Simon (author), Miljavec, Damijan (mentor)

V magistrskem delu je opisan proces modeliranja elektromagnetnih vibracij elektronsko komutirane sesalne enote z metodo končnih elementov. V začetnem poglavju so opisani različni viri in mehanizmi nastanka vibracij in hrupa pri električnih strojih. V nadaljevanju je na splošno opisano delovanje sinhronskih motorjev s trajnimi magneti, ter proces generiranja elektromagnetnih sil. Glavni del naloge predstavlja opis izgradnje sklopljenega numeričnega modela, ki je sestavljen iz 3D elektromagnetnega modela ter 3D strukturnega modela. Posamezen model je bil verificiran na podlagi meritev vzorca elektronsko komutirane sesalne enote. Verificiran sklopljen model je bil uporabljen na rešitvi s katero je bil v praksi odpravljen hrup elektronsko komutirane sesalne enote.

Abstract

The thesis describes the process of modeling electromagnetic vibrations of an electronically commutated vaccum motor using a finite element method. The initial chapter describes the various sources and mechanisms for creating vibrations and noise in electrical machines. The following chapter describes the operation of synchronous permanent magnet motors and also the process of generating electromagnetic forces. The main part of this thesis is the description of the construction of a coupled numerical model consisting of a 3D electromagnetic model and a 3D structural model. Each model was verified on the basis of the measurements of an electronically commutated vacuum motor sample. The verified coupled model was used on a solution that in practice eliminated the noise of an electronically commutated vaccum motor.
