20.500.12556/RUL-97609 Izdelava naprave za merjenje magnetne neuravnoteženosti elektromotorja Design of a test rig for measuring unbalanced magnetic pull of an electric motor Rotorje elektromotorjev je možno s kvalitetnim balansiranjem tudi v serijski proizvodnji zelo dobro masno uravnotežiti ter s tem zmanjšati sile in posledično vibracije ter hrup. Z zelo dobro masno uravnoteženostjo pridejo do izraza druge sile, kot je problem magnetne neuravnoteženosti elektromotorja. Da bi le to lahko izmerili in ovrednotili njen vpliv, je potrebno izdelati merilno napravo. Delo obravnava konstruiranje in izdelavo merilne naprave ter opis in analizo testne meritve. Predstavljena naprava omogoča merjenje sile, ki jih generira magnetna neuravnoteženost v manjših elektromotorjih. The rotors of electric motors can be well balanced in mass production, thus reducing the forces and consequently vibrations and noise. A very good mass balance results in the expression of other forces, such as the problem of unbalanced magnetic pull. The minimised mass imbalance causes the previously relatively small forces, such as unbalanced magnetic pull, to become more pronouced. In order to measure and evaluate the unbalanced magnetic pull, a device capable of measuring its impact had to be constructed. This thesis describes the design and construction of said measuring device. Some test measurements were subsequently preformend and analysed. The constructed device enables the measurements caused by unbalanced magnetic pull in small electric motors. magnetna neuravnoteženost elektromotorja masna neuravnoteženost elektromotorja elektromagnetne sile dinamična ekscentričnost rotorja zračna reža univerzalni elektromotor rotor unbalanced magnetic pull rotating unbalance electromagnetic forces dynamic eccentricity of rotor air gap universal electric motor rotor true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2017-10-28 07:15:18 2017-10-28 07:15:20 2023-10-27 12:53:39 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 204029 1327.pdf 1327.pdf 1 D00F7888B498085114C4AEBA4CC70F50 570e850b9f673241d0e2bd0ca5a1ea96fcdf3b70edda7a72af7e5c9fffb03c57 3b0f58a3-a1b4-11eb-a523-00155dcfd717 20.500.12556/rul/12e724eb-4103-4ca9-bf95-887f39fb9e98 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=106667 Fakulteta za strojništvo 0 0 0
