Uma unethuba lokuqaqa isishumeki esijikelezayo sizibuthe, ngokuvamile uzobona isakhiwo sangaphakathi esifana nalesi esiboniswe ngenhla.I-encoder kazibuthe yakhiwe shaft engumshini, isakhiwo segobolondo, umhlangano we-PCB ekugcineni kwesishumeki, kanye nesishumeki esincane.uzibuthe wediskiukuzungeza nge-shaft ekugcineni kwe-shaft mechanical.
Ingabe isifaki khodi sikazibuthe siyikala kanjani impendulo yendawo yokuzungezisa?
I-Hall Effect: ukukhiqizwa komehluko ongaba khona kuyo yonke i-conductor ethwala amandla kagesi lapho inkambu kazibuthe isetshenziswa ekuqondeni kwe-perpendicular kuleso sokugeleza kwamanje.
Uma inkambu kazibuthe esetshenziswa ku-conductor izungeziswa iqonde lapho kukhonjiswa umcibisholo ongenhla nendlela yokugeleza yamanje njenge-eksisi, umehluko ongaba khona weHholo uzoshintsha ngenxa yokushintsha kwe-engeli phakathi kwendawo kazibuthe ne-conductor, futhi ushintsho inkambiso umehluko ongase ube khona ijika sinusoidal.Ngakho-ke, ngokusekelwe ku-voltage ezinhlangothini zombili ze-conductor enikwe amandla, i-engeli yokuzungeza yenkundla kazibuthe ingabalwa ngokuhlehla.Lena indlela eyisisekelo yokusebenza yesifaki khodi sikazibuthe lapho ikala impendulo yendawo yokuzungezisa.
Ngokufanayo nomgomo wokuthi isixazululi sisebenzisa amasethi amabili wamakhoyili okukhiphayo ahambisanayo, izingxenye ezimbili (noma ezimbili) zokungeniswa kwehholo ezinezikhombisi-ndlela zamanje ezihambisanayo nazo ziyadingeka kusishumeki esiyizibuthe ukuze kuqinisekiswe ukuxhumana okuyingqayizivele phakathi kwendawo ezungezayo yenkundla kazibuthe. kanye ne-voltage ephumayo (inhlanganisela).
Namuhla, izinzwa zeHholo (ama-chips) asetshenziswa kumakhodi kazibuthe ngokuvamile anezinga eliphezulu lokuhlanganisa, elingagcini nje ngokuhlanganisa izingxenye ze-semiconductor yehholo kanye neziyingi ezihlobene nokucubungula isignali nokulawula, kodwa futhi lihlanganisa izinhlobo ezahlukene zamamojula okukhipha isignali, njenge-sine ne-cosine analog. amasignali, amasiginali wezinga ledijithali legagasi lesikwele noma amayunithi aphumayo okuxhumana kwebhasi.
Ngale ndlela, faka umazibuthe ongunaphakade njengozibuthe we-Neodymium onesinki okhiqiza insimu kazibuthe ekupheleni kwe-encoder shaft ejikelezayo, beka i-chip sensor yehholo okukhulunywe ngayo ngenhla ebhodini lesifunda le-PCB, bese usondela kuzibuthe unomphela ekugcineni kwesishumeki. shaft ngokwezidingo ezithile (isiqondiso nebanga).
Ngokuhlaziya ukuphuma kwesiginali ye-voltage kusuka kunzwa yehholo ngebhodi lesekethe le-PCB, indawo ejikelezayo yerotha yesishumeki ingabonakala.
Isakhiwo kanye nesimiso sokusebenza sekhodi kazibuthe sinquma isidingo esikhethekile mayelana nalo uzibuthe ongunaphakade njengezinto zikazibuthe, umumo kazibuthe, isiqondiso sokuzibuthe, njll. Ngokuvamile.uzibuthe we-Neodymium ozibuthe ngokulinganaI-disc iyindlela engcono kakhulu yamagnetic.I-Ningbo Horizon Magnetics inokuhlangenwe nakho ekunikezeni abakhiqizi abaningi bamakhodi kazibuthe anosayizi abathile.I-diametrical Neodymium disk magnetic, D6x2.5mm kanye ne-D10x2.5mm diametric disc Neodymium ozibuthe okungamamodeli adume kakhulu.
Kungabonakala ukuthi uma kuqhathaniswa nesishumeki sendabuko esibonakalayo, isifaki khodi sikazibuthe asidingi idiski yekhodi eyinkimbinkimbi nomthombo wokukhanya, inani lezingxenye lincane, futhi isakhiwo sokuthola silula.Ngaphezu kwalokho, i-Hall element ngokwayo nayo inezinzuzo eziningi, njengesakhiwo esiqinile, usayizi omncane, isisindo esilula, impilo ende yesevisi, ukumelana nokudlidliza, ukungesabi uthuli, uwoyela, umhwamuko wamanzi nokungcoliswa kwenkungu kasawoti noma ukulinda ukugqwala.
Lapho ubuchwepheshe bokufaka ikhodi kazibuthe busetshenziswa kumpendulo yendawo yokuzungeza yemoto kagesi, iisilinda uzibuthe we-NdFeBye-encoder kazibuthe ingafakwa ngokuqondile ekugcineni kwe-motor shaft.Ngale ndlela, ingakwazi ukuqeda i-bearing yenguquko yokuhlanganisa (noma ukuhlanganisa) edingekayo uma usebenzisa isifaki khodi sendabuko, futhi ifinyelele isikali sendawo ngaphandle kokuthinta, esinciphisa ubungozi bokwehluleka komshini wekhodi (noma ngisho nokulimala) ngenxa yokudlidliza kweshafthi ewumshini ngesikhathi. ukusebenza kwenjini kagesi.Ngakho-ke kusiza ukuthuthukisa ukuzinza kokusebenza kwemoto kagesi.
