Doorka Saamaynta Hoolka ICs ee Matoorka BLDC
Saamaynta Hoolka ICs waxay door muhiim ah ka ciyaartaa matoorada BLDC iyagoo ogaanaya booska rotor-ka, taasoo u oggolaanaysa in si sax ah loo xakameeyo wakhtiga socodka hadda socda ee gariiradaha stator.
Matoorka BLDCXakamaynta
Sida ku cad shaxanka, nidaamka kontoroolka mootada BLDC waxa uu aqoonsanayaa booska rotor-ka wareegta, ka dibna waxa uu farayaa darawalka kontoroolka mootada in uu hadda u beddelo gariiradda, si uu bilaabo wareegtada mootada.
Ogaanshaha booska rotor waa qayb muhiim ah oo ka mid ah habkan.
Ku guuldareysiga in la ogaado booska rotor-ka ayaa ka hortagaya in marxaladda tamarta lagu hirgeliyo waqtiga saxda ah ee loo baahan yahay si loo ilaaliyo xiriirka ugu wanaagsan ee ka dhexeeya stator iyo rotor, taasoo keentay wax soo saarka qulqulka hoose.
Marka ugu xun, matoorku ma wareego.
Saamaynta Hall ICs waxay ogaataa booska rotor-ka iyagoo beddelaya danabkooda wax soo saarka markay ogaadaan qulqulka magnetic.
Saamaynta Hoolka Meelaynta IC ee Matoorka BLDC
Sida shaxanka lagu muujiyey, saddexda saamaynta Hall ICs ayaa si siman loogu qaybiyey 360° (xagalka korantada) ee wareegga rotor-ka.
Calaamadaha wax soo saarka ee saddexda Hoolka ICs ee lagu ogaanayo goobta magnetic rotor-ka ayaa isbeddelaya marka la isku daro 60 ° kasta oo wareeg ah oo ku wareegsan wareegga 360 ° ee wareegga.
Isku darka calaamaduhu waxay beddelaan socodka hadda socda ee gariiradda. Marxalad kasta (U, V, W), rotor-ku waa la tamar-geliyay oo wuxuu wareegaa 120 ° si uu u soo saaro S pole/N.
Soo jiidashada birlabeedka iyo dib u celinta ka dhex dhalata rotor-ka iyo gariiradda ayaa sababa in rotor-ku uu wareego.
Wareejinta korantada ee wareegga wadista ilaa gariiradda waxaa lagu hagaajiyaa iyadoo loo eegayo waqtiga wax soo saarka ee Saamaynta Hall IC si loo gaaro kontorool wareeg oo waxtar leh.
Maxaa bixiyamatoorada gariir la'aantanolol dheer? Isticmaalka Saamaynta Hoolka si aad ugu Wadid Matoorada Burshla'aanta ah. Waxaan isticmaalnaa Saamaynta Hallka si aan u xisaabino booska matoorka oo aan u beddelno calaamadda wadista si habboon.
Sawiradani waxay muujinayaan sida calaamada waduhu isu bedelo wax soo saarka Hall Saamaynta dareemayaasha.
