Ikamva lemoto liya kuba “librashi” emva kwayo yonke loo nto!Iingenelo kunye nokungeloncedo, umsebenzi kunye nobomi beemoto ezingenabrashi!|

Isishwankathelo

Iinjini ze-Brushless ze-DC ziye zaphuphuma kumashishini ahlukeneyo njengezambuku eziphambeneyo, zaba yinkwenkwezi efanelekileyo ekhulayo kushishino lweemoto.Ngaba sinokwenza uqikelelo olunesibindi - kwixesha elizayo, ishishini leemoto liya kungena kwixesha "leebrashi"?

Iinjini ze-Brushless DC azinazo iibhrashi kunye nabahambi, kungoko igama labo.Ibandakanya umzimba wemoto kunye nomqhubi, kwaye iyimveliso eqhelekileyo ye-mechatronic.Njengomntu "omtsha" kushishino lweemoto, nangona imbali yeemoto ze-brushless ze-DC ezingena e-China ayinde, kwaye ixabiso liphezulu kunelo leemoto ezixutywayo, ngenxa yeenzuzo ezicacileyo zeemoto ezingenazintambo, ukuqhubela phambili kophuhliso kunokuchazwa njenge ngokukhawuleza.Emva kokungena eTshayina, yathandwa ngokukhawuleza ngamashishini afana nezixhobo zasekhaya, iimoto, iinqanawa kunye noomatshini, kwaye yahlala kwindawo kumashishini ahlukeneyo kwaye yaphuhliswa ngokukhawuleza.

Kutheni le nto iimowutha ezingenabrashi zinendawo?

Ixabiso eliphantsi ngokungathandabuzekiyo ligxininise kuhlaselo lweshishini kwiimoto ezingenabrushless, kutheni le nto inokuhlala kwindawo yentengiso yeemoto ngexesha elifutshane?Enyanisweni, oku kufana ne-Apple.Ngethuba nje umphumo wokusetyenziswa kunye nomgangatho unokuqinisekiswa, unokutsala abathengi abathembekileyo.Umzekelo, ixabiso leemveliso ze-elektroniki ze-Apple liphezulu kunomndilili, kodwa imarike isatshisa.Ngokucacileyo, xa umgangatho kunye nexabiso linokukhethwa kuphela, abathengi abanamandla okuthenga basaza kubeka kuqala kwisiphumo sokusetyenziswa.

inzuzo:

(1) Ibhrashi, ukuphazamiseka okuphantsi

I-brushless motor isusa i-brush, kwaye olona tshintsho luthe ngqo kukuba akukho spark sombane esiveliswayo xa i-motor brushed isebenza, enciphisa kakhulu ukuphazamiseka kwe-spark yombane kwisixhobo serediyo esilawulwa kude.

(2) Ingxolo ephantsi kunye nokusebenza kakuhle

I-motor ye-brushless ayinayo iibhulashi, amandla okubetha ayancipha kakhulu ngexesha lokusebenza, ukusebenza kakuhle, kwaye ingxolo iya kuba ngaphantsi kakhulu.Le nzuzo yinkxaso enkulu yokuzinza komzekelo.

(3) Ubomi obude kunye neendleko eziphantsi zokugcina

Ngaphandle kwebrashi, ukunxitywa kwemoto ye-brushless ikakhulu kwi-bearing.Ukusuka kwindawo yokujonga i-mechanical, i-brushless motor iphantse ibe yi-motor-free motor.Xa kuyimfuneko, kufuneka kuphela ukwenza ukugcinwa kokususa uthuli.Ngokuthelekisa yangaphambili kunye nelandelayo, uya kuzazi iingenelo ze-brushless motor kwi-motor brushed, kodwa yonke into ayikho ngokupheleleyo.I-brushless motor inesantya esisezantsi sokusebenza kwetorque kunye netorque enkulu.Iimpawu zentsebenzo yemoto ye-brushless ayinakuphinda ithathelwe indawo, kodwa ngokumalunga nokulula kokusetyenziswa kweemoto ezingenazintambo, kunye neendlela zokunciphisa iindleko zabalawuli be-brushless kunye nophuhliso kunye nokhuphiswano lwemarike yetekhnoloji ye-brushless ekhaya nakwamanye amazwe, inkqubo yamandla e-brushless. kwinqanaba lophuhliso olukhawulezayo kunye nokuthandwa, okukwakhuthaza kakhulu ukuphuhliswa kwentshukumo yemodeli.

ukusilela:

(1) I-friction inkulu kwaye ilahleko inkulu

Abahlobo abakudala bemodeli baye badibana nale ngxaki xa bedlala ngeenjini ezixutywe ngaphambili, oko kukuthi, emva kokusebenzisa i-motor kangangexesha elithile, kuyimfuneko ukuvula i-motor ukucoca iibrashi zekhabhoni zemoto, elixesha- okutyayo kunye nokusebenza ngamandla, kunye nokuqina kwesondlo akukho ngaphantsi kokucoca indlu.

(2) Ubushushu bukhulu kwaye ubomi bufutshane

Ngenxa yokwakheka kwemoto exutyiweyo, ukuchasana koqhagamshelwano phakathi kwebrashi kunye ne-commutator kukhulu kakhulu, okukhokelela kuxhathiso olukhulu lwemoto, ekulula ukuvelisa ubushushu, kwaye umazibuthe osisigxina yinto ethintela ubushushu.Ukuba iqondo lobushushu liphezulu kakhulu, intsimbi yamagnetic iya kwenziwa demagnetized., ukwenzela ukuba ukusebenza kwe-motor kuhlaziywe kwaye ubomi be-motor brushed buchaphazeleke.

(3) Ukusebenza okuphantsi kunye namandla aphantsi okuvelisa

Ingxaki yokufudumeza yemoto exutyiweyo ekhankanywe ngasentla ibangelwa ikakhulu kukuba i-current iyasebenza ekuxhathiseni kwangaphakathi kwemoto, ngoko ke amandla ombane aguqulwa abe ngamandla obushushu ukuya kwinqanaba elikhulu, ngoko ke amandla okuphuma kwemoto ebrashiweyo. ayikho enkulu, kwaye ukusebenza kakuhle akukho phezulu.

Indima yee-motorless brushless

I-brushless motor ikwasisixhobo esiguqula amandla ombane abe ngamandla omatshini.Ngokusebenzisa amandla ombane, amandla omatshini angafunyanwa ukufezekisa iinjongo ezithile.Yintoni ukusetyenziswa kwemoto brushless ngokubanzi?Ingasetyenziswa kwishishini elincinci lezixhobo zasekhaya, njengefan yombane eqhelekileyo.Ngapha koko, i-brushless motor iguqula amandla ombane abe ngamandla oomatshini, kwaye fan yombane iya kujika ikuzise imvakalelo epholileyo.Ukongeza, umtshini wengca kwishishini legadi usebenzisa i-brushless motor.Ukongeza, izixhobo zombane kwishishini lezixhobo zamandla nazo zisebenzisa ii-motor brushless.Indima ye-brushless motor kukuguqula amandla ombane abe ngamandla oomatshini, ukuze adlale indima kubomi bomntu wonke kwaye aphucule umgangatho wobomi bomntu wonke.

Ngoku i-brushless DC motor ikwazile ukutshintsha ngokupheleleyo ummiselo wesantya se-DC motor, isiguquli sefrequency + umgaqo wesantya sokuguqula isantya semoto, i-asynchronous motor + isantya sokunciphisa isantya.Idibanisa zonke iingenelo zeemoto zeDC zemveli ngelixa isusa ibrashi yekhabhoni kunye nesakhiwo seringi sokutyibilika, kwaye ineempawu ezibalaseleyo zetorque.Inokusebenza kakuhle kwetorque kwisantya esiphakathi nesisezantsi, itorque enkulu yokuqala kunye nencinci yokuqala yangoku, ukulawulwa kwesantya esingenanyathelo, uluhlu olubanzi lolawulo lwesantya, kunye nomthamo owomeleleyo wokugcwala.Ngaphaya koko, ubomi bangoku beenjini eziqhelekileyo ezibrashwayo bumalunga neeyure ezingama-10,000, kwaye ubomi beenjini ze-DC ezingenabrush buphindaphindene kaninzi.

Ukongeza, ngenxa yokuba i-brushless motor ngokwayo ayinayo i-excitation kunye nelahleko yebrashi ye-carbon, ilahleko ye-multi-stage deceleration iyapheliswa, kwaye izinga lokulondolozwa kwamandla elibanzi linokufikelela kwi-20% ~ 60%, ngoko ke umahluko wamaxabiso kunye neenjini eziqhelekileyo unokuthembela kuphela. ukonga amandla.Emva konyaka omnye, iindleko zokuthenga ziya kufunyanwa kwakhona.Ukongeza, urhulumente uye wakhuthaza ukulondolozwa kwamandla kunye nokukhuselwa kwendalo kwiminyaka yamuva nje.Iimotor ezingena-brush zinokuthiwa ziyindlela yophuhliso lweemoto.
