Kuki ibikoresho byamashanyarazi (nkimyitozo yintoki, gusya inguni, nibindi) muri rusange bakoresha moteri yasunitswe ahomoteri idafite amashanyarazi?Kugira ngo ubyumve, mubyukuri ntabwo bisobanutse mumurongo cyangwa ibiri.

Moteri ya DC igabanijwemo moteri yasunitswe na moteri idafite brush.“Brush” ivugwa hano yerekeza kuri karuboni.Brush ya karubone isa ite?

Kuki moteri ya DC ikenera gusya karubone?Ni irihe tandukaniro riri hagati ya karuboni ya karubone kandi idafite?Reka turebe hasi!

Ihame rya moteri ya DC yasunitswe

Nkuko bigaragara ku gishushanyo 1, iyi ni igishushanyo mbonera cyerekana moteri ya DC brush.Imashini ebyiri zihamye zinyuranye, igiceri gishyirwa hagati, impande zombi za coil zahujwe nimpeta ebyiri zumuzingi zumuringa, impande zombi zimpeta zumuringa zihura na brush ya karubone ihamye, hanyuma DC igahuzwa kugeza ku mpande zombi za karuboni.amashanyarazi.

ishusho 1

Nyuma yo guhuza amashanyarazi, ikigezweho cyerekanwa numwambi mubishusho 1.Ukurikije amategeko y’ibumoso, igiceri cyumuhondo gikorerwa imbaraga za electromagnetic hejuru;coil yubururu ikorerwa imbaraga zihagaritse kumashanyarazi.Rotor ya moteri itangira kuzunguruka ku isaha, na nyuma yo kuzunguruka dogere 90, nkuko bigaragara ku gishushanyo cya 2:

ishusho 2

Muri iki gihe, icyuma cya karubone kiri mu cyuho kiri hagati y’impeta zombi z'umuringa, kandi ikizunguruka cyose ntigifite umuyaga.Ariko munsi yibikorwa bya inertia, rotor ikomeza kuzunguruka.

ishusho 3

Iyo rotor ihindukiriye kumwanya wavuzwe haruguru mugikorwa cya inertia, umuyonga wa coil werekanwa mumashusho 3. Ukurikije itegeko ryibumoso, coil yubururu ikorerwa imbaraga za electromagnetic hejuru;igiceri cy'umuhondo gikorerwa imbaraga za electromagnetic ihanamye.Moteri ya moteri ikomeza kuzenguruka ku isaha, nyuma yo kuzunguruka dogere 90, nkuko bigaragara ku gishushanyo cya 4:

Igicapo 4

Muri iki gihe, umwanda wa karubone uri mu cyuho kiri hagati yimpeta zombi z'umuringa, kandi nta muyoboro uhari muri coil yose.Ariko munsi yibikorwa bya inertia, rotor ikomeza kuzunguruka.Noneho subiramo intambwe yavuzwe haruguru, kandi uruziga rurakomeza.

DC moteri idafite moteri

Nkuko bigaragara ku gishushanyo cya 5, iyi ni igishushanyo mbonera cyerekana imiterere ya amoteri ya DC.Igizwe na stator na rotor, aho rotor ifite inkingi ya magneti;hari ibice byinshi bya coil bikomeretsa kuri stator, kandi hariho ishusho 6 yibiceri.

Igicapo 5

Iyo tunyuze amashanyarazi kuri stator coil 2 na 5, coil 2 na 5 zizabyara umurima wa magneti.Stator ihwanye na magnet bar, aho 2 ni S (Amajyepfo) pole na 5 ni N (Amajyaruguru).Kubera ko inkingi za rukuruzi zihuje igitsina zikururana, N pole ya rotor izazenguruka kumwanya wa coil 2, naho S pole ya rotor izunguruka kumwanya wa coil 5, nkuko bigaragara ku gishushanyo cya 6.

Ishusho 6

Noneho dukuraho umuyagankuba wa stator coil 2 na 5, hanyuma tugahita tugenda kuri stator coil 3 na 6. Muri iki gihe, ibishishwa 3 na 6 bizabyara umurima wa magneti, kandi stator ihwanye na magneti bar. , aho 3 ni S (amajyepfo) pole na 6 ni N (amajyaruguru).Kubera ko inkingi za rukuruzi zihuje igitsina zikururana, N pole ya rotor izazenguruka kumwanya wa coil 3, naho S pole ya rotor izunguruka kumwanya wa coil 6, nkuko bigaragara ku gishushanyo 7.

Igicapo 7

Muri ubwo buryo nyene, imiyoboro ya stator ya 3 na 6 irakurwaho, hanyuma ikanyuzwa kuri stator coil 4 na 1. Muri iki gihe, ibishishwa 4 na 1 bizabyara umurima wa rukuruzi, kandi stator irasa kuri magnet bar, aho 4 ari S (amajyepfo) pole na 1 ni N (amajyaruguru).Kubera ko inkingi za rukuruzi zihuje igitsina zikurura mugenzi we, N pole ya rotor izunguruka kumwanya wa coil 4, na S pole ya rotor izunguruka kumwanya wa coil 1.

Kugeza ubu, moteri yazengurutse igice cyuruziga….Igice cya kabiri kizenguruka ni kimwe nihame ryabanje, ntabwo rero nzabisubiramo hano.Turashobora kumva gusa moteri ya DC idafite uburobyi nko kuroba karoti imbere yindogobe, kugirango indogobe ihore yerekeza kuri karoti.

Nigute dushobora guhererekanya neza kuri coil zitandukanye mubihe bitandukanye?Ibi bisaba uruzinduko rugezweho… ntabwo birambuye hano.

Kugereranya ibyiza nibibi

DC brush moteri: gutangira byihuse, feri mugihe, kugenzura umuvuduko uhamye, kugenzura byoroshye, imiterere yoroshye nigiciro gito.Ingingo ni uko bihendutse!igiciro gihenze!igiciro gihenze!Byongeye kandi, ifite nini nini yo gutangira, nini nini (rotation force) kumuvuduko muke, kandi irashobora gutwara umutwaro uremereye.

Nyamara, kubera ubushyamirane buri hagati ya brush ya karubone nigice cyogutwara abagenzi, moteri ya DC ya brush ikunda kwibasirwa nubushyuhe, ubushyuhe, urusaku, kwivanga kwa electromagnetiki kubidukikije, gukora neza no kubaho igihe gito.Kuberako amashanyarazi ya karubone aribintu bikoreshwa, bikunda kunanirwa kandi bigomba gusimburwa nyuma yigihe runaka.

Brushless DC moteri: Kuberako imoteri ya DCikuraho ibikenerwa byo gusya karubone, ifite urusaku ruke, nta kubungabunga, igipimo gito cyo kunanirwa, igihe kirekire cya serivisi, igihe gihoraho cyo gukora na voltage, no kutivanga mubikoresho bya radio.Ariko bihenze!Birahenze!Birahenze!

Ibikoresho Byimbaraga

Ibikoresho byimbaraga nibikoresho bisanzwe bikoreshwa mubuzima.Hariho ibirango byinshi n'amarushanwa akaze.Umuntu wese yunvikana cyane.Kandi ibikoresho byingufu bigomba gutwara umutwaro uremereye kandi bigomba kugira itara rinini ryo gutangira, nkimyitozo yintoki hamwe n imyitozo.Bitabaye ibyo, iyo gucukura, moteri irashobora kunanirwa gukora byoroshye kuko biti ya myitozo irahamye.

Iyumvire nawe, moteri ya DC yogejwe ifite igiciro gito, itara rinini ryo gutangira, kandi irashobora gutwara imitwaro iremereye;nubwo moteri idafite brush ifite igipimo gito cyo kunanirwa nubuzima burebure, irazimvye, kandi itara ryo gutangira riruta kure cyane ya moteri yasunitswe.Niba warahawe amahitamo, wahitamo ute, ngira ngo igisubizo kirigaragaza.
