I-brushless DC motor iquka umzimba wemoto kunye nomqhubi, kwaye iyimveliso eqhelekileyo ye-mechatronic.Ngenxa yokuba i-brushless ye-DC motor isebenza ngokuzilawula, ayizukongeza ukuqala ukujika kwi-rotor njenge-synchronous motor enomthwalo onzima oqala phantsi komgaqo wesantya esiguqukayo, kwaye ayiyi kubangela i-oscillation kunye nokulahlekelwa kwesinyathelo xa umthwalo utshintsha. ngequbuliso.Iimagnethi ezisisigxina ze-brushless DC motors ezincinci kunye ezinomthamo ophakathi ngoku ubukhulu becala zenziwe ngezinto ezinqabileyo zomhlaba neodymium-iron-boron (Nd-Fe-B) ezinamaqondo aphezulu ombane.Ke ngoko, umthamo womhlaba onqabileyo wemagnethi esisigxina ye-brushless motor iyancitshiswa ngobungakanani besakhelo esinye xa kuthelekiswa nenqanaba lesithathu leasynchronous motor yomthamo ofanayo.
I-motor ebrashiweyo: I-motor brushed iqulethe isixhobo se-brush, kwaye yi-motor ejikelezayo, enokuthi iguqule amandla ombane kumandla omatshini (i-motor), okanye iguqule amandla omatshini kumandla ombane (ijenereyitha).Ngokungafaniyo neenjini ze-brushless, izixhobo zebrashi zisetyenziselwa ukwazisa okanye ukukhupha i-voltage kunye neyangoku.Imotor ebrashiweyo sisiseko sazo zonke iinjini.Ineempawu zokuqalisa ngokukhawuleza, ukunyathela ngexesha elifanelekileyo, ukulawulwa kwesantya esigudileyo kuluhlu olubanzi, kunye nesekethe yolawulo elula.
Umgaqo osebenzayo we-brush motor kunye ne-brushless motor.
1. Imoto ebrashiweyo
Xa i-motor isebenza, i-coil kunye ne-commutator iyajikeleza, kodwa intsimbi yamagnetic kunye ne-carbon brush ayijikelezi.Ukutshintsha okutshintshileyo kolwalathiso lwangoku lwekhoyili lufezwa ngumhambisi kunye nebrashi ejikelezayo ngemoto.Kwishishini lemoto yombane, iimotor ezixutyiweyo zohlulwe zibe ziimotor ezinesantya esiphezulu kunye neemotor ezinesantya esiphantsi.Kukho iiyantlukwano ezininzi phakathi kweenjini ezibrashwayo kunye neenjini ezingasebenziyo.Ukusuka kwigama, kunokubonwa ukuba iimotor ezixutyiweyo zineebhrashi zekhabhoni, kwaye iimotor ezingenazo iibrashi zekhabhoni.
Imoto yebrashi inamacandelo amabini: stator kunye nerotor.I-stator inezibonda zamagnetic (uhlobo lwe-winding okanye uhlobo lwemagnethi esisigxina), kwaye i-rotor ine-windings.Emva kokufakelwa kombane, intsimi yamagnetic (i-magnetic pole) yenziwe kwakhona kwi-rotor.I-angle efakiweyo yenza ukuba i-motor ijikeleze phantsi komtsalane we-stator kunye ne-rotor magnetic fields (phakathi kwe-N pole kunye ne-S pole).Ngokutshintsha indawo yebrashi, i-angle phakathi kwe-stator kunye ne-rotor magnetic poles inokutshintshwa (kucingelwa ukuba i-pole magnetic ye-stator iqala ukusuka kwi-engile, i-pole magnetic ye-rotor ikwelinye icala, kwaye isalathiso esivela Ipali yemagnethi yerotor ukuya kwipali kazibuthe yestator yindlela yokujikeleza kwemoto) indlela, ngaloo ndlela itshintsha indlela yokujikeleza kwemoto.
2. I-brushless motor
I-brushless motor ithatha ukuguqulwa kwe-elektroniki, i-coil ayihambi, kwaye i-pole magnetic ijikeleza.I-brushless motor isebenzisa iseti yezixhobo ze-elektroniki ukuva indawo yepoli yemagnethi esisigxina kwindawo yeHolo.Ngokwale mbono, isekethe ye-elektroniki isetyenziselwa ukutshintshela ulwalathiso lwangoku kwikhoyili kwangexesha ukuze kuqinisekiswe ukuba amandla kazibuthe ngendlela echanekileyo aveliswa ukuqhuba i-motor, ukuphelisa ukusilela kwi-motor brushed.
Ezi sekethe ngabalawuli beemoto.Umlawuli wemoto engena-brushless unokuqonda eminye imisebenzi engakwaziyo ukwenza ibhrashi yemoto, njengokulungelelanisa i-angle yokutshintsha amandla, ukuqhotsa i-motor, ukubuyisela umva i-motor, ukutshixa i-motor, kunye nokusebenzisa umqondiso we-brake ukumisa umbane kwi-motor. .Ngoku i-alarm alarm lock yemoto yebhetri isebenzisa ngokupheleleyo le misebenzi.
Iingenelo ezahlukeneyo zeemoto ezingenabrashi kunye neenjini ezibrashiweyo
I-motor brushed ineenzuzo zayo, oko kukuthi, ixabiso liphantsi kwaye ulawulo lulula.Iindleko zeenjini ze-brushless ziphezulu kakhulu, kwaye ulwazi olungaphezulu luyimfuneko ekulawuleni.Ngokukhula okuqhubekayo kwetekhnoloji yokulawula i-brushless motor, ukuhla kweendleko zamacandelo e-elektroniki, ukuphuculwa kweemfuno zabantu kumgangatho wemveliso, kunye noxinzelelo kugcino lwamandla kunye nokunciphisa ukukhutshwa, ngakumbi nangakumbi iinjini ezibrashwayo kunye neenjini ze-AC ziya kutshintshwa DC brushless motors.
Ngenxa yobukho beebrashi kunye nee-commutators, iimoto ezixutyiweyo zinesakhiwo esintsonkothileyo, ukuthembeka okulambathayo, ukusilela okuninzi, umthwalo onzima wokulungisa, ubomi obufutshane, kunye neentlantsi zokutshintsha zinokuphazamiseka kombane.I-motor ye-brushless ayinayo iibhulashi, ngoko akukho jongano oluhambelanayo, ngoko icocekile, inengxolo encinci, eneneni ayifuni ukugcinwa, kwaye inobomi obude.
Kwezinye iimveliso eziphantsi, kunokwenzeka ngokupheleleyo ukusebenzisa i-motor brushed, nje ukuba itshintshwe ngexesha.Nangona kunjalo, kwezinye iimveliso zexabiso eliphezulu, ezifana nezilungisi zomoya, iimoto, kunye nabashicileli, ixabiso lokutshintsha i-hardware liphezulu kakhulu, kwaye ayifanelekanga ukutshintshwa rhoqo kwamalungu, ngoko ubomi obude bee-motor ze-DC ziye zaba ngcono. ukhetho.
I-Shenzhen Zhongling Technology Co., Ltd ibigxile kuphando lwe-stepper motor kunye ne-servo motor ukusukela ekusekweni kwayo, kwaye ifumene inani lamalungelo awodwa abenzi kwaye inamava atyebileyo.Iinjini ze-stepper kunye neenjini ze-servo eziveliswe yinkampani zikwathengiswa ekhaya nakwamanye amazwe, ibe lolona khetho lubalaseleyo kwiinkampani ezininzi zeerobhothi kunye neenkampani ezininzi zokuvelisa izixhobo ezizenzekelayo.
