Uvod<\/h4>\n

42BLF03 je 3-fazni istosmjerni motor bez \u010detkica Nema17 (DC motor bez \u010detkica - BLDC) brzine vrtnje 4000RPM, struje 5.7A, napona 24VDC i snage 78W.<\/p>\n

Op\u0107enito o DC motorima bez \u010detkica (DC motor bez \u010detkica - BLDC)<\/h3>\n

Istosmjerni motori bez \u010detkica rade na istom principu magnetskog privla\u010denja i odbijanja kao bru\u0161eni istosmjerni motori, ali su ne\u0161to druga\u010dije gra\u0111eni. Umjesto mehani\u010dkog komutatora i \u010detkica, magnetsko polje statora rotira pomo\u0107u elektroni\u010dke komutacije. To zahtijeva kori\u0161tenje aktivne upravlja\u010dke elektronike.<\/p>\n

U motoru bez \u010detkica, rotor ima permanentne magnete pri\u010dvr\u0161\u0107ene na njega, a stator ima namote. Motori bez \u010detkica mogu se izraditi s rotorom na unutarnjoj strani ili s rotorom na vanjskoj strani namota (ponekad se nazivaju i "outrunner" motor).<\/p>\n

Broj namota koji se koriste u motoru bez \u010detkica predstavlja broj faza. Iako se motori bez \u010detkica mogu izraditi s razli\u010ditim brojem faza, naj\u010de\u0161\u0107i su trofazni motori bez \u010detkica.<\/p>\n

Tri namota motora bez \u010detkica spojena su u konfiguraciji "zvijezda" ili "trokut". Motor 42BLF03 ima konfiguraciju zvijezde.<\/p>\n

\"DC<\/a><\/p>\n

Trofazni istosmjerni motori bez \u010detkica mogu se izraditi u razli\u010ditim magnetskim konfiguracijama koje se nazivaju polovi. Najjednostavniji trofazni motori imaju dva pola: rotor ima samo jedan par magnetskih polova, jedan sjeverni i jedan ju\u017eni. Motori se tako\u0111er mogu izraditi s vi\u0161e polova, \u0161to zahtijeva vi\u0161e magnetskih sekcija u rotoru i vi\u0161e namota u statoru. Ve\u0107i broj polova mo\u017ee osigurati ve\u0107u izvedbu, iako se vrlo velike brzine bolje posti\u017eu s manjim brojem polova.<\/p>\n

Kako pokre\u0107emo istosmjerni motor bez \u010detkica?<\/h3>\n

Za pogon trofaznog istosmjernog motora bez \u010detkica moramo mijenjati napon na svakoj fazi u odre\u0111enom nizu. Da bi se to postiglo, koriste se tri pogonska kruga "pola mosta", od kojih se svaki sastoji od dva prekida\u010da. Prekida\u010di mogu biti bipolarni tranzistori, IGBT ili MOSFET ovisno o potrebnom naponu i struji.<\/p>\n

Ovaj DC motor bez \u010detkica kompatibilan je s BLDC-8015A drajver istosmjernog motora bez \u010detkica<\/a> u Napajanje 24V<\/a> (150W ili 200W).<\/p>\n
