Indima yeeHall Effect ICs kwiBLDC Motor
Ii-IC ze-Hall effect zidlala indima ebalulekileyo kwiimoto ze-BLDC ngokufumanisa indawo ye-rotor, okuvumela ulawulo oluchanekileyo lwexesha lokuhamba kombane kwiikhoyili ze-stator.
Imoto yeBLDCUlawulo
Njengoko kubonisiwe kumfanekiso, inkqubo yolawulo lweemoto ze-BLDC iyayibona indawo yerotor ejikelezayo kwaye emva koko iyalele umqhubi wolawulo lweemoto ukuba atshintshele umbane kwikhoyili, ngaloo ndlela eqalisa ukujikeleza kweemoto.
Ukuchonga indawo yerotor yinxalenye ebalulekileyo yale nkqubo.
Ukungaphumeleli ukubona indawo yerotor kuthintela isigaba sokunika amandla ekuphunyezweni ngexesha elichanekileyo elifunekayo ukugcina ubudlelwane obufanelekileyo bokujika phakathi kwe-stator kunye nerotor, nto leyo ekhokelela kwimveliso ye-torque engaphantsi komgangatho.
Okona kubi kukuba, injini ayizukujikeleza.
Ii-IC ze-Hall effect zibona indawo ye-rotor ngokutshintsha i-voltage yazo xa zibona i-magnetic flux.
Ukubekwa kweHall Effect IC kwiBLDC Motor
Njengoko kubonisiwe kumfanekiso, ii-IC ezintathu zeHall effect zisasazwe ngokulinganayo kumjikelo we-360° (i-engile yombane) we-rotor.
Imiqondiso yeziphumo ze-IC ezintathu zeHall effect ezibona intsimi yemagnethi yerotor ziyatshintsha xa zidibene rhoqo emva kwe-60° yokujikeleza kujikelezo lwe-360° lwerotor.
Olu dibaniso lwemiqondiso lutshintsha umsinga ohamba ngekhoyili. Kwisigaba ngasinye (U, V, W), i-rotor inikwa amandla kwaye ijikeleza i-120° ukuvelisa i-S pole/N pole.
Ukutsala kunye nokugxothwa kwemagnethi okwenziwa phakathi kwerotor kunye nekhoyili kubangela ukuba irotor ijikeleze.
Ukudluliselwa kwamandla ukusuka kwisekethe yokuqhuba ukuya kwikhoyili kulungiswa ngokwexesha lokukhupha le-Hall effect IC ukuze kufezekiswe ulawulo olusebenzayo lokujikeleza.
Yintoni enikaiimoto zokungcangcazela ezingenabhrashiubomi obude? Ukusebenzisa iHall Effect ukuqhuba iiBrushless Motors. Sisebenzisa iHall Effect ukubala indawo yemoto kunye nokutshintsha isignali yedrive ngokufanelekileyo.
Le mifanekiso ibonisa indlela isignali yedrayivu etshintsha ngayo xa iphuma kwiisensa zeHall Effect.
