Rkhumbula indlela esebenza ngayo i-motor ye-DC brush
Ukuze uqonde ngcono indlelaiimoto ezingenabhrashiumsebenzi, kufuneka siqale sikhumbule indlela esebenza ngayo i-brush DC motor, njengoko yayisetyenziswa ixesha elide ngaphambi kokuba kubekho ii-brushless DC motors.
Kwindlela eqhelekileyoImoto yeDC, kukho iimagnethi ezisisigxina ngaphandle kunye ne-armature ejikelezayo ngaphakathi. Iimagnethi ezisisigxina aziguquki, ngoko ke zibizwa ngokuba yi-stator. I-armature iyajikeleza, ngoko ke ibizwa ngokuba yi-rotor. I-armature ine-electromagnet. Xa usebenzisa umbane kule electromagnet, idala intsimi yemagnethi kwi-armature etsala kwaye igxotha iimagnethi kwi-stator. I-commutator kunye neebhrashi zezona zinto ziphambili ezahlula i-DC brush motor kwezinye iintlobo zeemoto.
Yintoni iBrushless DC Motor?
Injini yeDC engenabhrashi okanyeI-BLDCyimoto yombane esebenza ngamandla angqalileyo kwaye ivelisa intshukumo yayo ngaphandle kweebhrashi njengakwiimoto zeDC eziqhelekileyo.
Iimoto ezingenabhrashi zithandwa kakhulu kule mihla kuneemoto zeDC ezibrashiweyo eziqhelekileyo kuba zisebenza kakuhle, zinokulawula isantya esichanekileyo se-torque kunye nesantya sokujikeleza, kwaye zibonelela ngokuqina okuphezulu kunye nengxolo ephantsi yombane, ngenxa yokungabikho kweebrashi.
Zisebenza Njani iiBrushless DC Motors?
Umgaqo wokusebenza wemoto encinci engenamabhrashi ubandakanya ukusebenzisana kwemagnethi ejikelezayo kunye nekhoyili engashukumiyo. Ngokungafaniyo neemoto zemveli ezixutyiweyo, akukho bhrashi okanye ii-commutator ezibonakalayo ezibandakanyekayo. Kwimoto engenamabhrashi, i-rotor equlathe iimagnethi ezisisigxina ijikeleza i-stator engashukumiyo eneekhoyili ezininzi okanye ii-windings. Ezi khoyili zibekwe zijikeleze i-stator ngamaxesha athile. I-elektroniki yemoto ilawula umbane ohamba ngekhoyili nganye ukwenza intsimi yemagnethi ejikelezayo. Le ntsimi yemagnethi ejikelezayo isebenzisana neemagnethi ezisisigxina kwi-rotor, nto leyo ebangela ukuba i-rotor ijikeleze. Indlela kunye nesantya sokujikeleza kunokulawulwa ngokulungelelanisa ixesha kunye nobukhulu bombane ohamba ngekhoyili. Ukuze kujikelezwe kakuhle, ii-sensors zesikhundla zihlala zidityaniswa kwimoto ukuze zinike impendulo kwisekethe yolawulo. Le ngxelo ivumela umlawuli wemoto ukuba amisele ngokuchanekileyo indawo ye-rotor kwaye alungise umbane kwiikhoyili ngokufanelekileyo. Ngokubanzi, ii-motor ezincinci ezingenamabhrashi zisebenza ngokusebenzisa ukusebenzisana phakathi kwentsimi yemagnethi ejikelezayo eveliswa ziikhoyili ze-stator kunye neemagnethi ezisisigxina kwi-rotor, okuvumela ukujikeleza okusebenzayo nokuchanekileyo ngaphandle kwesidingo seebhrashi zomzimba okanye ii-commutators.
Isiphelo
Iimoto ezincinci ezingenamabhrashi zisebenza kakuhle kakhulu, zihlala ixesha elide, zilawula ngokuchanekileyo, kwaye zinciphisa ingxolo xa kuthelekiswaiimoto zemveliZisetyenziswa kakhulu kumashishini ahlukeneyo, kuquka i-aerospace, izixhobo zonyango, iirobhothi, kunye ne-elektroniki yabathengi. Njengoko ubuchwepheshe kunye nemfuno yolawulo oluchanekileyo lweemoto ziqhubeka zikhula, ukusetyenziswa kweemoto ezincinci ezingenamabhrashi kulindeleke ukuba kwande kwixesha elizayo.
