1. Isimiso sokusebenza:

Isimiso esisebenzayo se-DC yokupholisa fan: ngokusebenzisa i-DC voltage kanye ne-electromagnetic induction, amandla kagesi aguqulwa abe yimishini yokushintshanisa i-blade. Ikhoyili ne-IC ziyaqhubeka zishintshwa, futhi indingilizi kazibuthe yokungeniswa ishayela ukujikeleza kwekhaba.

Isimiso esisebenzayo se-AC fan: Iqhutshwa ngumthombo wamandla we-AC, futhi i-voltage izoshintsha phakathi kokuhle nokubi. Akunciki ekulawulweni kwesifunda ukukhiqiza amandla kazibuthe. Imvamisa yokuphakelwa kwamandla ilungisiwe, futhi ijubane eliguqukayo lezigxobo zikazibuthe ezikhiqizwe yishidi lensimbi lesilicon kunqunywa ubukhulu bokuphakelwa kwamandla. Ukuphakama kwemvamisa, isivinini sokushintsha amandla kazibuthe sishesha, futhi ijubane lokujikeleza lishesha kakhulu. Kodwa-ke, imvamisa akufanele isheshe kakhulu, ukushesha kakhulu kuzodala ubunzima ekuqaleni.

Ukwakheka kwesakhiwo:

I-Rotor ye-DC yokupholisa fan ifaka ama-fan blades we-DC okupholisa fan, okuyimithombo yokugeleza komoya, i-axis fan, futhi asetshenziselwa ukuxhasa ukuzungeza kwama-fan blade, iringi yamagnor magnetic, uzibuthe waphakade, futhi ukhuthaze ukhiye wejubane lokushintsha amandla kazibuthe, ifreyimu yendandatho kazibuthe, indandatho kazibuthe engaguquki. Ngaphezu kwalokho, kufaka phakathi iziphethu ezisekelayo. Ngalezi zingxenye, ingxenye yonke nengxenye yezimoto kumiselwe ukujikeleza kwesifo sofuba. Ukuqondiswa kokujikeleza kukhiqizwa, futhi isivinini sokujikeleza esisebenzayo nesikhulu kubalulekile. Ijubane layo elilawula ukusebenza lihle, futhi ukulawula kulula.

Isakhiwo sangaphakathi se-AC fan (isigaba esisodwa) sakhiwa ngama-coil windings amabili, eyodwa ukuqala kokugwedla, lawa ma-windings amabili axhunyiwe ochungechungeni, okwenza amaphuzu amathathu, iphuzu lochungechunge ukuphela okuvamile, futhi isiqalo sokuqeda ukuqala ukusebenza kokuqalisa kokuphela Ukuphela kokugwedla ukuphela kokugijima. Ngaphezu kwalokho, i-capacitor yokuqala iyadingeka. Umthamo uvame ukuba phakathi kwe-12uf futhi i-voltage yokumelana imvamisa i-250v. Kukhona izixhumi ezimbili. Umkhawulo owodwa uxhunywe ekugcineni kovalo lokuqala kanti olunye luxhunywe ekugcineni kokugwedla okugijima ukwakha unxantathu. Ukunikezwa kwamandla (asikho isidingo sokuhlukanisa ulayini obukhoma nomugqa ongathathi hlangothi) kuxhunywe ekugcineni kokugijima okusebenzayo (okungukuthi, kuxhunywe komunye umkhawulo we-capacitor), kanti enye ixhunywe ekugcineni okuvamile , futhi ucingo lokugxila luxhunywe kugobolondo lezimoto.

3. Izici ezibonakalayo:

Izinto ze-DC zokupholisa fan: Yenziwe nge-alloy material, futhi ubude bempilo bungasetshenziswa ngokuqhubekayo amahora angaphezu kwama-50,000. Isakhiwo sangaphakathi se-DC sine-transformer nebhodi elikhulu lokulawula (kufaka phakathi isekhethi yokuguqulwa kwemvamisa, isihlungi sesilungisi, isekhethi se-amplifier, njll.), Okungeke kuthinteke ukwehla kwamandla kagesi. Impilo yesevisi ende.

Isakhiwo sangaphakathi somlandeli we-AC ikakhulukazi siyisiguquli. Iningi lezinto ezisetshenziselwa umlandeli we-AC zenziwe ngezinaliti zokukhipha zasekhaya, izinaliti ngokuvamile ze-tungsten noma izinto zensimbi engagqwali. Uma i-voltage ishintshashintsha kakhulu, izothinta impilo yesevisi ye-transformer.
