Iyini i-brushless motor futhi isebenza kanjani?

Iyini i-brushless motor futhi isebenza kanjani?Sizophendula le mibuzo kulesi sihloko.

Esikhathini samathuluzi wesimanje wamandla namagajethi, akumangazi ukuthi amamotho ama-brushless avame kakhulu emikhiqizweni esiyithengayo.Nakuba i-brushless motor yasungulwa maphakathi nekhulu le-19, ayizange ikwazi ukuhweba kuze kube ngu-1962.

I-Brushless motor, ngenxa yokusebenza kahle kwayo okuphezulu, ukudluliswa kwetorque ebushelelezi, ukuqina okuphezulu kanye nesivinini sokugijima, kancane kancane ithatha indawo yemoto yokudweba.Izicelo zabo, esikhathini esidlule, ziye zanqunywa kakhulu izindleko ezengeziwe zezilawuli zezimoto eziyinkimbinkimbi, ezidingekayo ukuze kusetshenziswe injini.

Ukusebenza kwangaphakathi kwezinjini zombili kuyafana.Lapho ikhoyili yenjini inikwa amandla, idala indawo kazibuthe yesikhashana exosha noma eheha uzibuthe ongunaphakade.

Amandla avelayo abe eseguqulwa abe ukujikeleza kwe-shaft ukwenza umshini usebenze.Njengoba i-shaft ijikeleza, i-current iqondiswe kumakhoyili ahlukene, ukuze insimu yamagnetic igcinwe ikhange futhi ixoshwe, ivumela i-rotor ukuthi ijikeleze ngokuqhubekayo.

I-brushless motor iphumelela kakhulu kune-motor yokudweba ohlelweni lokuguqula amandla kagesi abe amandla emishini.Azinayo i-commutator, enciphisa ukunakekelwa nokuba yinkimbinkimbi, futhi inciphisa ukuphazamiseka kwe-electromagnetic.

Bangakwazi ukuthuthukisa i-torque ephezulu, impendulo enhle yesivinini, futhi bangakwazi ukulawula kalula i-chip eyodwa (iyunithi yokulawula imoto).

Ziphinde zisebenze ngaphakathi kwebanga elibanzi lejubane, okuvumela ukulawula ukunyakaza okuhle kanye ne-torque lapho uphumule.

I-brushless motor kanye ne-wire drawing motor ihluke kakhulu ngesakhiwo.

Ibhulashi lisetshenziswa kunjini yebhulashi ukudlulisa okwamanje kuma-windings ngokusebenzisa othintana nabo abahambayo.

Nokho, injini brushless ayidingi commutator.Amandla kazibuthe enjini ashintshwa yi-amplifier eqalwa idivayisi ehlehlayo.Isibonelo isifaki khodi esibonakalayo esikala ukunyakaza okuhle ngoba akuncikile esigabeni sokunyakaza.

Ama-windings enjini yokudweba atholakala ku-rotor futhi atholakala ku-brushless motor stator.Isidingo sebhulashi singaqedwa ngokubeka ikhoyili endaweni emile ye-stator noma injini.

Ngamafuphi, umehluko omkhulu phakathi kwe-brushless motor kanye ne-brushed motor ukuthi awekho omagnethi abangaguquki nezintambo ezijikelezayo (ama-brushed), futhi ama-brushless motors anezintambo ezimisiwe kanye nozibuthe abajikelezayo.Inzuzo eyinhloko i-brushless motor ngaphandle kokungqubuzana, ngaleyo ndlela inciphisa ukushisa futhi ithuthukise ukusebenza kahle jikelele.
