Nigute ushobora gukuraho urusaku rwa moteri ya DC?

Moteri ya DC ihujwe no gutanga amashanyarazi binyuze muri brush ya commutator.Iyo umuyaga unyuze muri coil, umurima wa magneti ubyara imbaraga, kandi imbaraga zituma moteri ya DC izunguruka kugirango itange umuriro.Umuvuduko wa moteri ya DC yogejwe igerwaho muguhindura imbaraga zumurimo cyangwa imbaraga za magneti.Moteri ya Brush ikunda kubyara urusaku rwinshi (haba acoustic na mashanyarazi).Niba urusaku rudatandukanijwe cyangwa rukingiwe, urusaku rw'amashanyarazi rushobora kubangamira uruziga rwa moteri, bikaviramo gukora moteri idahindagurika.Urusaku rw'amashanyarazi ruterwa na moteri ya DC rushobora kugabanywamo ibyiciro bibiri: kwivanga kwa electronique na urusaku rw'amashanyarazi.Imirasire ya electromagnetique iragoye kuyisuzuma, kandi iyo ikibazo kimaze kugaragara, biragoye kubitandukanya nandi masoko y urusaku.Kwivanga kwa radiyo cyangwa guhuza imirasire ya electromagnetic biterwa no kwinjiza amashanyarazi cyangwa imirasire ya electronique ituruka hanze.Urusaku rw'amashanyarazi rushobora kugira ingaruka kumikorere yumuzunguruko.Urusaku rushobora kuganisha ku kwangirika kwimashini.

Iyo moteri ikora, rimwe na rimwe ibibatsi bibaho hagati ya brux na commutator.Imirabyo ni imwe mu mpamvu zitera urusaku rw'amashanyarazi, cyane cyane iyo moteri itangiye, kandi ugereranije n'umuyaga mwinshi utemba ugenda.Imiyoboro yo hejuru mubisanzwe itera urusaku rwinshi.Urusaku rusa narwo rubaho mugihe umwanda ukomeje kuba udahungabana hejuru ya commutator kandi ibyinjira muri moteri biri hejuru cyane kuruta uko byari byitezwe.Ibindi bintu, harimo na insulasiyo zakozwe hejuru yimodoka, nazo zirashobora gutera ihungabana ryubu.

EMI irashobora gushira mubice byamashanyarazi ya moteri, bigatuma moteri ikora nabi kandi igatesha agaciro imikorere.Urwego rwa EMI rushingiye ku bintu bitandukanye nkubwoko bwa moteri (brush cyangwa brushless), gutwara ibinyabiziga no gutwara ibintu.Mubisanzwe, moteri yogejwe izabyara EMI nyinshi kuruta moteri idafite amashanyarazi, niyo yaba ubwoko ubwo aribwo bwose, igishushanyo cya moteri kizagira ingaruka cyane kumeneka wa electromagnetic, moteri ntoya yogejwe rimwe na rimwe itanga RFI nini, cyane cyane LC Low pass filter hamwe nicyuma.

Irindi rusaku rutanga amashanyarazi ni amashanyarazi.Kubera ko kurwanya imbere kwamashanyarazi atari zeru, muri buri cyiciro cyizunguruka, moteri idahoraho izahindurwa ihindagurika ryumuvuduko kumashanyarazi, kandi moteri ya DC izabyara mugihe cyihuta.urusaku.Kugirango ugabanye amashanyarazi ya electronique, moteri ishyirwa kure yumuzunguruko ushoboka.Icyuma cya moteri isanzwe itanga ingabo ihagije kugirango igabanye EMI yo mu kirere, ariko icyuma cyongeweho kigomba gutanga kugabanya EMI neza.

Ibimenyetso bya electromagnetique byakozwe na moteri birashobora kandi guhurira mumuzunguruko, bigakora ibyo bita uburyo-busanzwe bwo kwivanga, bidashobora gukurwaho no gukingira kandi birashobora kugabanywa neza na LC yoroheje-yoroheje.Kugirango urusheho kugabanya urusaku rwamashanyarazi, birakenewe gushungura kumashanyarazi.Mubisanzwe bikorwa wongeyeho ubushobozi bunini (nka 1000uF no hejuru) hejuru yumuriro wamashanyarazi kugirango ugabanye imbaraga zokwirinda amashanyarazi, bityo bigatezimbere igisubizo cyigihe gito, kandi ukoresheje igishushanyo cyumuzunguruko cyoroshye (reba ishusho hepfo) kugeza kuzuza ibirenze, birenze urugero, LC muyunguruzi.

Ubushobozi nubushake mubisanzwe bigaragara muburyo bwumuzunguruko kugirango harebwe impuzandengo yumuzunguruko, gukora LC muyunguruzi ruto, kandi uhagarike urusaku rwumuvuduko ukomoka kuri brush ya karubone.Ubushobozi bwo guhagarika cyane cyane imbaraga za voltage zatewe no gutandukana gutunguranye kwa brush ya karubone, kandi capacitor ifite imikorere myiza yo kuyungurura.Kwishyiriraho capacitor muri rusange bihujwe ninsinga zubutaka.Inductance irinda cyane cyane ihinduka ritunguranye ryikinyuranyo hagati yicyuma cya karuboni nu rupapuro rwumuringa wa komuteri, kandi guhagarara birashobora kongera imikorere yubushakashatsi hamwe ningaruka zo kuyungurura LC muyunguruzi.Inductors ebyiri na capacator ebyiri zikora imikorere ya LC muyunguruzi.Imashini ikoreshwa cyane cyane mu gukuraho ingufu z'amashanyarazi zatewe na brush ya karubone, naho PTC ikoreshwa mu gukuraho ingaruka z'ubushyuhe bukabije ndetse no kwiyongera gukabije kuri moteri.
