Kumenya ihame ryakazi rya brush moteri na brushless moteri

Koza ihame ryo gukora moteri

Imiterere nyamukuru yamoteri idafite moterini stator + rotor + brush, kandi torque iboneka mukuzunguruka umurima wa magneti kugirango usohokane ingufu za kinetic. Brush ihora ihura na commutator kugirango ikore amashanyarazi kandi ihindure icyiciro mukuzunguruka

Brush moteri YAKORESHEJWE imashini, pole ya magneti ntigenda, kuzunguruka coil.Iyo moteri ikora, coil na commutator bizunguruka, mugihe ibyuma bya magnetiki na brush ya karubone ntibikora.Guhinduranya icyerekezo cya coil icyerekezo cyakozwe na commutator hamwe na brush izunguruka hamwe na moteri.

Muri moteri ya brush, iyi nzira ni uguhuza ingufu ebyiri zinjiza amaherezo ya coil, nayo, igatondekanya mu mpeta, igatandukanywa hamwe n’ibikoresho bikingira hagati, bigakora ikintu cyose kimeze nka silinderi, gihinduka ibinyabuzima inshuro nyinshi hamwe na moteri ya moteri. , amashanyarazi binyuze mu nkingi ebyiri ntoya ikozwe muri karubone (brush ya karubone), munsi yigitutu cyumuvuduko wimpeshyi, uhereye kumyanya ibiri yihariye ihamye, umuvuduko winjiza amashanyarazi, ingingo ebyiri zumuzingi wa silindrike kugeza kuri coil ya seti ya amashanyarazi.

Nkamoterikuzunguruka, ibishishwa bitandukanye cyangwa inkingi zitandukanye za coil imwe zongerwamo ingufu mugihe gitandukanye, kugirango habeho itandukaniro ryiza rya Angle hagati ya ns pole ya coil itanga imbaraga za magnetique na ns pole ya statut ya magneti ihoraho.Imirasire ya rukuruzi ikururana kandi ikazunguruka, ikabyara imbaraga kandi igasunika moteri kuzunguruka. Electrode ya karubone iranyerera ku mutwe winsinga nka brush hejuru yikintu, bityo izina "brush".

Kunyerera hamwe bizatera guterana no gutakaza amashanyarazi ya karubone, bigomba gusimburwa buri gihe.Guhindura no kuzimya hagati ya brush ya karubone n'umutwe winsinga ya coil birashobora gutera amashanyarazi, kumeneka kwa electronique no kubangamira ibikoresho bya elegitoroniki.

Brushless moteri ikora

Muri moteri idafite amashanyarazi, ingendo ikorwa nu muzunguruko mugenzuzi (muri rusange salle sensor + umugenzuzi, kandi tekinoroji igezweho ni magnetiki encoder).

Moteri idafite amashanyarazi ikoresha ingendo za elegitoronike, coil ntigenda, pole ya magneti irazunguruka. Moteri itagira amashanyarazi ikoresha ibikoresho bya elegitoronike kugirango yumve aho pole ya magneti ya magneti ihoraho ikoresheje element ya SS2712.Ukurikije ubu buryo, umuzunguruko wa elegitoronike ukoreshwa muguhindura icyerekezo cyumuyaga muri coil mugihe gikwiye kugirango habeho kubyara ingufu za magneti muburyo bwiza bwo gutwara moteri. Kuraho ibibi bya moteri ya brush.

Iyi mizunguruko yitwa moteri igenzura.Umugenzuzi wa moteri idafite amashanyarazi arashobora kandi kumenya imirimo imwe n'imwe idashobora kugerwaho na moteri idafite amashanyarazi, nko guhindura amashanyarazi ahinduranya Angle, feri ya moteri, gutuma moteri ihinduka, gufunga moteri, no gukoresha feri yerekana guhagarika amashanyarazi kuri moteri.Ubu imodoka ya bateri yimodoka ya elegitoronike ifunga, kumikoreshereze yuzuye yiyi mirimo.

Moteri ya Brushless dc nigicuruzwa gisanzwe cya mechatronics, kigizwe numubiri wa moteri nu mushoferi.Kuko moteri ya brushless dc ikoreshwa muburyo bwo kugenzura byikora, ntabwo izongera intangiriro yo guhinduranya rotor nka moteri ya syncronique hamwe na moteri yihuta yihuta. n'umutwaro uremereye utangira, kandi ntabwo bizatera ihungabana no gusohoka mugihe umutwaro uhindutse.

Itandukaniro ryuburyo bwo kugenzura umuvuduko hagati ya moteri ya brush na moteri idafite brush

Mubyukuri, kugenzura ubwoko bubiri bwa moteri ni kugenzura voltage, ariko kubera ko brush idafite dc Yifashisha ingendo za elegitoronike, bityo rero irashobora kugerwaho no kugenzura ibyuma bya digitale, kandi dc idafite amashanyarazi ikoresheje komatori ya karuboni, ukoresheje silikoni igenzurwa na gakondo gakondo ishobora kugenzurwa. , byoroshye.

1. Igikorwa cyo kugenzura umuvuduko wa moteri ya brush ni uguhindura voltage yumuriro wa moteri.Nyuma yo guhinduka, voltage numuyoboro uhindurwa na commutator hamwe na brush kugirango uhindure imbaraga zumurima wa magneti wakozwe na electrode kugirango ugere kuri intego yo guhindura umuvuduko.Iyi nzira izwi nko kugenzura igitutu.

2. Igikorwa cyo kugenzura umuvuduko wa moteri idafite amashanyarazi ni uko voltage yumuriro wa moteri idahinduka, ikimenyetso cyo kugenzura ihinduka ryamashanyarazi kirahinduka, kandi igipimo cyo guhinduranya umuyoboro mwinshi MOS uhindurwa na microprocessor kugeza menya ihinduka ryumuvuduko.Iyi nzira yitwa guhinduranya inshuro.

Itandukaniro ryimikorere

1. Brush moteri ifite imiterere yoroshye, igihe kirekire cyiterambere hamwe nikoranabuhanga rikuze

Kera mu kinyejana cya 19, igihe moteri yavukaga, moteri ifatika yari uburyo butagira umuyonga, aribwo moteri ya ac squirrel-cage asynchronous moteri, yakoreshejwe cyane nyuma yibisekuru bigenda bisimburana.Nyamara, moteri idafite imbaraga ifite inenge nyinshi zidashobora kurenga, bityo ko iterambere ryikoranabuhanga rya moteri ritinda.Byumwihariko, moteri ya dc idafite amashanyarazi ntiyashoboye gushyirwa mubikorwa byubucuruzi.Hamwe niterambere ryihuse ryikoranabuhanga rya elegitoronike, ryashyizwe mubikorwa byubucuruzi kugeza mu myaka yashize.Mubyukuri, iracyari mubyiciro bya ac moteri.

Moteri ya Brushless yavutse bidatinze, abantu bahimbye moteri ya dc brushless.Kuko uburyo bwa moteri ya dc brush buroroshye, bworoshye kubyara no gutunganya, byoroshye kubungabunga, byoroshye kugenzura; moteri ya Dc nayo ifite igisubizo cyihuse, itara rinini ritangira, kandi Irashobora gutanga imikorere ya torque kuva kuri zeru kugera kumuvuduko wagenwe, bityo yakoreshejwe cyane iyo isohotse.

2. Moteri ya brush idafite moteri ifite umuvuduko wo gusubiza byihuse kandi nini yo gutangira

Dc brushless moteri ifite igisubizo cyihuse cyo gutangira, nini yo gutangira itara, ihinduka ryihuse, hafi nta kunyeganyega byunvikana kuva kuri zeru kugeza kumuvuduko ntarengwa, kandi birashobora gutwara umutwaro munini mugihe utangiye. imbaraga zingirakamaro ni ntoya, itangira ryumuriro ni rito, ijwi ritangira rirasakuza, riherekejwe no kunyeganyega gukomeye, kandi umutwaro wo gutwara ni muto mugihe utangiye.

3. Moteri idafite dc idafite moteri ikora neza kandi ifite feri nziza

Moteri ya brushless igengwa nubuyobozi bwa voltage, bityo gutangira no gufata feri birahagaze, kandi imikorere yihuta nayo ihagaze neza. Moteri itagira amashanyarazi isanzwe igenzurwa no guhinduranya inshuro ya digitale, ibanza guhindura ac kuri dc, hanyuma dc ikagera kuri ac, kandi igenzura umuvuduko binyuze mumihindagurikire.Kubwibyo, moteri idafite brush ntigikora neza mugihe utangiye no gufata feri, hamwe no kunyeganyega kwinshi, kandi bizahagarara gusa mugihe umuvuduko uhoraho.

4, dc brush kugenzura ibinyabiziga neza

Dc brushless moteri isanzwe ikoreshwa hamwe nagasanduku kagabanya na decoder kugirango imbaraga zisohoka za moteri nini kandi igenzure neza, igenzura rishobora kugera kuri mm 0,01, hafi irashobora kureka ibice byimuka bigahagarara ahantu hose wifuza. Imashini zose zisobanutse ibikoresho ni dc igenzura neza neza.Kubera ko moteri idafite brush idahagaze neza mugihe cyo gutangira no gufata feri, ibice byimuka bizahagarara kumyanya itandukanye buri gihe, kandi umwanya wifuzwa urashobora guhagarikwa gusa na pin cyangwa imyanya ntarengwa.

5, dc brush ikoresha moteri igiciro ni gito, kubungabunga byoroshye

Bitewe nuburyo bworoshye bwa moteri ya dcless brush, igiciro cyumusaruro muke, abayikora benshi, ikoranabuhanga rikuze, bityo irakoreshwa cyane, nkinganda, ibikoresho byimashini zitunganya ibikoresho, ibikoresho bisobanutse, nibindi, niba moteri yananiwe, gusimbuza karuboni , buri cyuma cya karubone gikenera amadorari make, ahendutse cyane.Ikoranabuhanga rya moteri ridafite amashanyarazi ntirirakuze, igiciro kiri hejuru, igipimo cyo gusaba ni gito, cyane cyane kigomba kuba mubikoresho byihuta byihuta, nkibihe byo guhinduranya ikirere, firigo, nibindi. , brushless moteri yangiritse irashobora gusimburwa gusa.

6, nta brush, kwivanga hasi

Moteri ya Brushless ikuraho brush, impinduka itaziguye ni ukubura moteri ya brush ikora, bityo bikagabanya cyane kwangirika kwamashanyarazi kubikoresho bya radio bya kure.

7. Urusaku ruke no gukora neza

Hatariho guswera, moteri idafite amashanyarazi izagira umuvuduko muke mugihe ikora, ikora neza hamwe n urusaku rwo hasi cyane, ninkunga ikomeye yo gutuza kwimikorere yicyitegererezo.

8. Igihe kirekire cya serivisi hamwe nigiciro gito cyo kubungabunga

Koza moteri nkeya, idafite moteri yambara cyane cyane mubitwara, uhereye kumashini, moteri idafite amashanyarazi ni moteri idafite kubungabunga, mugihe bibaye ngombwa, kora gusa kubungabunga umukungugu.
