Ukuba unethuba lokuqhawula i-encoder yemagnethi ejikelezayo, uya kubona ngesiqhelo isakhiwo sangaphakathi esifana nesi siboniswe ngasentla. I-encoder magnetic yenziwe ngeshafti ematshini, isakhiwo seqokobhe, indibano yePCB ekupheleni kweencoder, kunye nencinci.idiskhi umazibutheukujikeleza kunye ne-shaft ekupheleni kwe-shaft mechanical.
Ingaba i-encoder yemagnethi iyilinganisa njani ingxelo yendawo yojikelezo?
I-Hall Effect: imveliso yomahluko onokuthi ubekho kuwo wonke umqhubi ophethe umbane wangoku xa umbane wemagnethi usetyenziswa kwicala le-perpendicular kuleyo ehamba ngoku.
Ukuba umhlaba wemagnethi osetyenziswa kumqhubi ujikeleziswa kwicala eliboniswe lutolo olungasentla kunye nendlela yokuhamba yangoku njenge-axis, umahluko onokubakho kwiHolo uya kutshintsha ngenxa yokutshintsha kwe-engile phakathi kwentsimi magnetic kunye nomqhubi, kunye utshintsho intsingiselo yomahluko onokwenzeka yigophe le-sinusoidal. Ngoko ke, ngokusekelwe kumbane kumacala omabini omqhubi onamandla, i-angle yokujikeleza yendawo yamagnetic ingabalwa ngokuphindaphindiweyo. Le yeyona ndlela isisiseko yokusebenza kwesixhobo sokufaka ikhowudi kwimagnethi xa silinganisa ingxelo yendawo ejikelezayo.
Ngokufana nomgaqo wokuba isicombululi sisebenzisa iiseti ezimbini zeekhoyili eziphuma ecaleni ngokulinganayo, ezimbini (okanye izibini ezimbini) izinto zokungenisa kwiholo ezinemikhomba-ndlela yangoku ehambelanayo nazo ziyafuneka kwi-encoder magnetic ukuqinisekisa unxibelelwano olulodwa phakathi kwendawo ejikelezayo yommandla wemagnethi. kunye ne-voltage yemveliso (ukudibanisa).
Kule mihla, izinzwa zeHolo (iitshiphu) ezisetyenziswa kwiikhowudi zemagnethi zinezinga eliphezulu lokudityaniswa, ezingahlanganisi nje kuphela amacandelo e-semiconductor yeholo kunye nokusetyenzwa kwemiqondiso ehambelanayo kunye neesekethe zolawulo, kodwa zikwadibanisa iintlobo ezahlukeneyo zeemodyuli zokuphuma komqondiso, njenge-sine kunye ne-cosine analog. imiqondiso, amaza amaza omgangatho wedijithali imiqondiso okanye iiyunithi zemveliso yonxibelelwano lwebhasi.
Ngale ndlela, fakela umazibuthe osisigxina njengemagnethi ye-Neodymium ene-sintered eyenza umhlaba wemagnethi ekupheleni kwe-encoder shaft ejikelezayo, beka i-holo sensor chip ekhankanywe ngasentla kwibhodi yesekethe ye-PCB, kwaye usondele kwimagnethi esisigxina ekupheleni kwe-encoder. shaft ngokweemfuno ezithile (ulwalathiso kunye nomgama).
Ngokuhlalutya imveliso yesignali yombane ukusuka kwinzwa yeholo ngebhodi yesekethe yePCB, indawo ejikelezayo yerotor ye-encoder inokuchongwa.
Ulwakhiwo kunye nomgaqo-siseko wokusebenza wekhowudi yemagnethi ithatha isigqibo ngemfuno ekhethekileyo malunga nalo mazibuthe osisigxina umzekelo imathiriyeli yemagnethi, imilo yemagnethi, icala lemagnetization, njl.umazibuthe weNeodymium enediametricallyidiski yeyona ndlela ilungileyo umazibuthe. I-Ningbo Horizon Magnetics inamava ekuboneleleni ngabavelisi abaninzi beekhowudi zemagnethi ezinobungakanani obuthile beiimagnethi zedisk zeNeodymium diametrical, i-D6x2.5mm kunye ne-D10x2.5mm diametric disc Neodymium umazibuthe ezizezona modeli zidumileyo.
Ingabonwa ukuba xa kuthelekiswa ne-encoder yendabuko ye-optical, i-encoder magnetic ayifuni idisk yekhowudi eyinkimbinkimbi kunye nomthombo wokukhanya, inani lamacandelo lincinci, kwaye isakhiwo sokufumanisa silula. Ngaphezu koko, iHolo yeHolo ngokwayo ineengenelo ezininzi, ezifana nolwakhiwo oluqinileyo, ubungakanani obuncinci, ubunzima obulula, ubomi benkonzo ende, ukuxhathisa ukungcangcazela, ukungoyiki uthuli, ioyile, umphunga wamanzi kunye nongcoliseko lwenkungu yetyuwa okanye ukulinda umhlwa.
Xa itekhnoloji ye-encoder yamagnetic isetyenziswa kwimo yokujikeleza impendulo yemoto yombane, isintered NdFeB umazibuthe cylinderye-encoder magnetic inokufakwa ngokuthe ngqo ekupheleni kwe-motor shaft. Ngale ndlela, inokuphelisa ukuthwala okudityanisiweyo okutshintshileyo (okanye ukudibanisa) okufunekayo xa usebenzisa i-encoder yengxelo yemveli, kwaye ufezekise umlinganiso wesikhundla sokungaqhagamshelwa, okunciphisa umngcipheko wokungaphumeleli kwe-encoder (okanye nomonakalo) ngenxa yokungcangcazela kweshaft yomatshini ngexesha. ukusebenza kwemoto yombane. Ngoko ke inceda ekuphuculeni uzinzo yokusebenza kwemoto yombane.
