Zamagetsi Chigawo Choyambirira cha IC LC898201TA-NH

Kufotokozera mwachidule:

LC898201 ndi LSI yoyendetsedwa ndi injini pamakamera owunikira omwe nthawi imodzi amayendetsa iris, makulitsidwe, kuyang'ana, ndikusintha usana/usiku.Imaphatikiza mabwalo awiri oyankha pa iris ndi kuwongolera koyang'ana, ndi mabwalo awiri owongolera ma stepper motor kuti makulitsidwe ndikusintha usana/usiku.Komanso, posankha ma mode, kuwongolera mayankho kumagwiritsidwa ntchito powongolera iris ndipo kuwongolera kwa ma stepper kumagwiritsidwa ntchito powonera, kuyang'ana, ndikusintha usana/usiku.

Mawu Oyamba

Dalaivala yamagalimoto ndi chosinthira, chifukwa ma drive apano ndi akulu kwambiri kapena voteji ndiyokwera kwambiri, ndipo chosinthira chonse kapena zida zamagetsi sizingagwiritsidwe ntchito ngati chosinthira kuwongolera mota.

Udindo wa woyendetsa galimoto: Udindo wa woyendetsa galimoto umatanthawuza momwe mungakwaniritsire kuwongolera kwa liwiro la injini yopanda ntchito mwa kuwongolera kozungulira komanso kuthamanga kwa injini, kuti mukwaniritse kuwongolera kwa ntchito.

Chithunzi chozungulira cha motor drive: Dongosolo loyendetsa galimoto limatha kuyendetsedwa ndi relay kapena transistor yamagetsi, kapena kugwiritsa ntchito thyristor kapena mphamvu ya MOS FET.Kuti mugwirizane ndi zowongolera zosiyanasiyana (monga mphamvu yogwirira ntchito ndi voteji ya injini, kuthamanga kwagalimoto, kuwongolera ndi kuwongolera kumbuyo kwa mota ya DC, ndi zina), mitundu yosiyanasiyana ya mabwalo oyendetsa galimoto iyenera kukwaniritsa zofunika zofunika.

Galimoto yamagetsi siimayamba ikapatsidwa mphamvu, ndipo imakhala yovuta kwambiri kukankhira ndikutsagana ndi phokoso la "kutsamwitsa".Izi ndikuti chingwe chamoto chimafupikitsidwa chifukwa cholumikizana ndi kugwirizana kwenikweni, ndipo chodabwitsa cha kukankhira ngolo ndi mizere itatu yayikulu yagalimoto imatha kutulutsidwa ndikuzimiririka, zomwe zikuwonetsa kuti wowongolera wathyoka ndipo ayenera m'malo mwa nthawi.Ngati kukadali kovuta kukhazikitsa, zikutanthauza kuti pali vuto ndi injini, ndipo mwina chifukwa chafupikitsa koyilo yamoto ikuwotchedwa.
