Haddii aad haysato fursad aad ku kala furfurto cod-bixiye magnetic rotary ah, waxaad caadi ahaan arki doontaa qaab-dhismeedka gudaha sida kan kor lagu muujiyey. Codeeyaha birlabku waxa uu ka kooban yahay usheeda dhexe, qaab dhismeed qolof ah, PCB-ga dhamaadka cod-bixiyaha, iyo mid yarmagnet discku rogmanaya usheeda dhexe ee usheeda dhexe ee farsamada.
Sidee buu u cabbiraa cod-bixiyaha birlabeedka?
Saamaynta Hoolka: soo saarista kala duwanaanshiyaha suurtagalka ah ee ka dhexeeya kirishbooyada ku socda korantada marka goob birlabeed ah lagu dabaqo jihada toosan ee socodka hadda.
Haddii goobta magnetic codsatay in kaari waxaa loo rogo jihada ay muujisay fallaadho kor ku xusan oo leh dariiqa socodka hadda sida dhidibka, Hall ka iman kara kala duwanaansho beddeli doonaa sababtoo ah isbeddelka xagal u dhexeeya field magnetic iyo kaari, iyo isbeddelka isbeddelka farqiga iman kara waa qalooca sinusoidal. Sidaa darteed, iyada oo ku saleysan danab labada dhinac ee kaari tamar leh, xagasha wareega ee goobta magnetic waxaa loo xisaabin karaa si kale. Tani waa habka aasaasiga ah ee shaqada ee codeeyaha birlabeedka marka la cabbirayo jawaab celinta booska wareegga.
Si la mid ah mabda'a ah in xaliyahu isticmaalo laba qaybood oo ah gariiradaha wax soo saarka siman, laba (ama laba lammaane) walxood induction hoolka leh jihooyinka hadda taagan ayaa sidoo kale looga baahan yahay encoder magnetic si loo hubiyo xiriirka gaarka ah ee u dhexeeya booska wareega ee goobta magnetic iyo danab wax-soo-saarka (isku-darka).
Maalmahan, dareemayaasha Hall (chips) loo isticmaalo encoders magnetic guud ahaan waxay leeyihiin heerar sare oo is dhexgalka, taas oo aan kaliya isku darin qaybaha semiconductor hall iyo habaynta signalada la xidhiidha iyo wareegyada sharciyaynta, laakiin sidoo kale mideeya noocyo kala duwan oo ah modules soo saarka signal, sida sine iyo cosine analoogga ah. calaamadaha, calaamadaha heerka dhijitaalka ah ee mowjadda labajibbaaran ama qaybaha soosaarka isgaarsiinta baska.
Sidan, ku rakib magnet joogto ah sida Neodymium magnet sinteed oo soo saara aag birlab ah oo ku yaal dhammaadka usheeda dhexe ee codeeyaha, dhig qalabka dareeraha hoolka ee kor ku xusan guddiga wareegga PCB, oo u dhawaado magnetka joogtada ah ee dhamaadka cod-bixiyaha usheeda dhexe sida waafaqsan shuruudaha qaarkood (jihada iyo masaafada).
Marka la falanqeeyo wax soo saarka signalka danab ee ka soo baxa dareeraha hoolka iyada oo loo marayo guddiga wareegga PCB, booska wareega ee rotor-ka codeeyaha ayaa la aqoonsan karaa.
Qaab dhismeedka iyo mabda'a shaqada ee encode magnetka ayaa go'aamiya shuruudaha gaarka ah ee ku saabsan magnetkan joogtada ah tusaale ahaan walxaha magnetka, qaabka magnetka, jihada magnetization, iwm.Neodymium magnetized diametricized magnetizeddisc waa ikhtiyaarka magnet ugu fiican. Ningbo Horizon Magnetics ayaa khibrad u leh bixinta soo saarayaasha badan ee encodes magnetic oo leh cabbirro kala duwanNeodymium-magnet-yada saxanka ah ee diametrical, D6x2.5mm iyo D10x2.5mm diametric disc Neodymium magnets kuwaas oo ah moodooyinka ugu caansan.
Waxaa la arki karaa in marka la barbar dhigo codeeyaha indhaha ee dhaqameed, magnetic encoder uma baahna saxan koodhka adag iyo isha iftiinka, tirada qaybaha ayaa ka yar, qaab-dhismeedka ogaanshaha waa ka fudud yahay. Intaa waxaa dheer, element Hall laftiisa sidoo kale waxay leedahay faa'iidooyin badan, sida qaab-dhismeedka adag, cabbir yar, miisaanka fudud, nolosha adeegga dheer, caabbinta gariirka, aan ka cabsanayn boodhka, saliidda, uumiga biyaha iyo wasakhowga milixda ama sugidda daxalka.
Marka tignoolajiyada encoder-ka birlabeedka lagu dabaqo ra'yi celinta booska wareega ee matoorka korantada,dhululubo magnet NdFeB sinteredee encoder magnetic si toos ah ayaa lagu rakibi karaa dhamaadka usheeda dhexe ee motor. Sidan, waxay baabi'in kartaa isku-xidhka ku-meel-gaadhka ah ee isku-xidhka (ama isku-xidhka) ee loo baahan yahay marka la isticmaalayo codeer-celin-celinta dhaqameed, oo lagu gaaro cabbirka booska aan la xiriirin, taas oo yareyneysa khatarta ah in codeerku guuldareysto (ama xitaa waxyeello) sababtoo ah gariirka farsamada gacanta inta lagu jiro shaqada matoorka korontada. Sidaa darteed waxay gacan ka geysaneysaa hagaajinta xasilloonida hawlgalka mashiinka korantada.
