Zithunzi za DRV8871
Chipangizo cha DRV8871 ndi choyendetsa galimoto cha brushed-DC cha osindikiza, zida, zida zamakampani, ndi makina ena ang'onoang'ono.Zolowetsa ziwiri zomveka zimayang'anira dalaivala wa H-bridge, yemwe ali ndi ma MOSFET anayi a N-channel omwe amatha kuwongolera ma mota molunjika mpaka 3.6-A pachimake chapano.Zolowetsazo zitha kukhala za bepulse-width modulated (PWM) kuti ziwongolere kuthamanga kwagalimoto, pogwiritsa ntchito njira zovunda zamakono.Kuyika zonse ziwiri kutsika kumalowa m'malo ogona opanda mphamvu.
Chipangizo cha DRV8871 chili ndi zozungulira zotsogola zamakono zomwe sizigwiritsa ntchito ma analogi voteji kapena resistor externalsense.Yankho lakale ili limagwiritsa ntchito cholumikizira chotsika mtengo, chotsika mphamvu kuti chikhazikitse mphamvu.Kutha kuchepetsa pano mpaka pamlingo wodziwika kumatha kuchepetsa kwambiri zofunikira zamakina ndi mphamvu zambiri zomwe zimafunikira kuti voteji ikhale yokhazikika, makamaka pamagetsi oyambira ndi ma stall.
Chipangizocho chimatetezedwa kwathunthu ku zolakwika ndi mabwalo amfupi, kuphatikiza kutsika kwamagetsi (UVLO), overcurrent (OCP), ndi kutentha kwambiri (TSD).Cholakwikacho chikachotsedwa, chipangizocho chimayambiranso kugwira ntchito bwino.
1. Kodi ogwira ntchito m'dipatimenti yanu ya R & D ndi ndani?Kodi ziyeneretso zanu ndi zotani?
-R & D Mtsogoleri: pangani dongosolo la nthawi yayitali la R & D ndikumvetsetsa momwe kafukufuku ndi chitukuko;Kuwongolera ndi kuyang'anira dipatimenti ya r&d kuti ikwaniritse njira zamakampani ndi mapulani apachaka a R&D;Kuwongolera kupita patsogolo kwa chitukuko cha mankhwala ndikusintha dongosolo;Khazikitsani gulu labwino kwambiri la kafukufuku wazinthu ndi chitukuko, kufufuza ndi kuphunzitsa ogwira ntchito zaukadaulo.
Woyang'anira R & D: pangani mankhwala atsopano a R & D ndikuwonetsa kuthekera kwa dongosolo;Kuyang'anira ndi kuyang'anira momwe ntchito ya R&d ikuyendera;Fufuzani zachitukuko chazinthu zatsopano ndikupereka mayankho ogwira mtima malinga ndi zomwe makasitomala amafuna m'magawo osiyanasiyana
Ogwira ntchito ndi R&d: sonkhanitsani ndikusankha zofunikira;Mapulogalamu apakompyuta;Kuyesa, kuyesa ndi kusanthula;Konzani zida ndi zida zoyeserera, zoyeserera ndi kusanthula;Lembani deta yoyezera, pangani mawerengedwe ndikukonzekera ma chart;Chitani kafukufuku wamawerengero
2. Kodi lingaliro lanu la kafukufuku ndi chitukuko ndi chiyani?
- Lingaliro lazinthu ndi kusankha kwazinthu ndikuwunika tanthauzo lazinthu ndi kapangidwe ka pulani ya projekiti ndi kuyezetsa kwachitukuko ndikutsimikizira kukhazikitsidwa kwa msika
