Yog tias koj muaj sijhawm los disassemble lub magnetic teb encoder, feem ntau koj yuav pom cov qauv sab hauv zoo li qhov qhia saum toj no.Lub tshuab magnetic encoder yog tsim los ntawm cov cuab yeej siv tshuab, lub plhaub qauv, lub rooj sib dhos PCB ntawm qhov kawg ntawm lub encoder, thiab me me.disc hlau nplaumrotating nrog cov ncej ntawm qhov kawg ntawm cov neeg kho tshuab ncej.
Lub magnetic encoder ntsuas qhov kev sib hloov txoj hauj lwm tawm tswv yim li cas?
Hall Effect: qhov tsim ntawm qhov sib txawv ntawm qhov sib txawv ntawm tus neeg xyuas pib nqa ntawm cov hluav taws xob tam sim no thaum lub chaw sib nqus siv nyob rau hauv cov kev taw qhia perpendicular mus rau qhov tam sim no ntws.
Yog hais tias lub magnetic teb thov rau tus neeg xyuas pib yog tig nyob rau hauv cov kev taw qhia qhia los ntawm xub xub saum toj no nrog rau tam sim no khiav txoj kev raws li lub axis, lub Hall muaj peev xwm sib txawv yuav hloov vim qhov kev hloov ntawm lub kaum sab xis ntawm lub magnetic teb thiab tus neeg xyuas pib, kev hloov pauv ntawm qhov sib txawv muaj peev xwm yog qhov nkhaus sinusoidal.Yog li ntawd, raws li qhov voltage ntawm ob sab ntawm lub energized conductor, lub kaum sab xis ntawm lub magnetic teb yuav raug xam rov qab.Qhov no yog qhov yooj yim ua hauj lwm mechanism ntawm ib tug sib nqus encoder thaum ntsuas kev sib hloov txoj hauj lwm tawm tswv yim.
Zoo ib yam li lub hauv paus ntsiab lus uas tus neeg daws teeb meem siv ob pawg ntawm kev sib koom ua ke ntawm cov zis coils, ob (lossis ob khub) nrog induction cov ntsiab lus nrog kev sib koom ua ke tam sim no kuj yuav tsum muaj nyob rau hauv cov khoom sib nqus sib nqus los xyuas kom meej cov ntawv sib txawv ntawm txoj haujlwm tig ntawm cov hlau nplaum. thiab cov zis voltage (combination).
Niaj hnub no, Hall sensors (chips) siv nyob rau hauv magnetic encoders feem ntau muaj ib tug high degree ntawm kev koom ua ke, uas tsis tsuas yog integrates nrog semiconductor Cheebtsam thiab muaj feem xyuam rau cov teeb liab ua thiab kev tswj circuits, tab sis kuj integrates ntau hom teeb liab tso zis modules, xws li sine thiab cosine analog. Pib ntsais koj teeb, square wave digital theem teeb liab lossis tsheb npav sib txuas lus tso zis units.
Nyob rau hauv txoj kev no, nruab ib lub hlau nplaum ruaj khov zoo li sintered Neodymium hlau nplaum uas ua rau muaj qhov sib nqus ntawm qhov kawg ntawm lub encoder rotating ncej, tso lub Hall sensor nti uas tau hais los saum toj no rau ntawm lub rooj tsavxwm PCB, thiab mus cuag cov hlau nplaum ruaj khov ntawm qhov kawg ntawm lub encoder. ncej raws li tej yam yuav tsum tau (kev taw qhia thiab nrug).
Los ntawm kev txheeb xyuas qhov hluav taws xob tawm hluav taws xob tawm ntawm lub tsev sensor los ntawm PCB pawg thawj coj saib xyuas, qhov kev sib hloov ntawm tus encoder rotor tuaj yeem txheeb xyuas tau.
Cov qauv thiab kev ua haujlwm ntawm cov hlau nplaum encode txiav txim siab qhov tshwj xeeb ntawm cov hlau nplaum ruaj khov no piv txwv li cov khoom siv hlau nplaum, cov duab hlau nplaum, cov kev taw qhia magnetization, thiab lwm yam.diametrically magnetized Neodymium hlau nplaumdisc yog qhov kev xaiv zoo tshaj plaws hlau nplaum.Ningbo Horizon Magnetics muaj kev paub txog hauv kev muab ntau lub tuam txhab sib nqus encodes nrog qee qhov ntau thiab tsawgdiametrical Neodymium disk hlau nplaum, D6x2.5mm thiab D10x2.5mm diametric disc Neodymium hlau nplaum uas yog cov qauv nrov tshaj plaws.
Nws tuaj yeem pom tau tias piv nrog cov khoom siv kho qhov muag ib txwm muaj, cov khoom sib nqus tsis xav tau cov lej cim disk thiab lub teeb pom kev zoo, cov khoom siv tsawg dua, thiab cov qauv nrhiav tau yooj yim dua.Ntxiv mus, Hall lub ntsiab nws tus kheej kuj muaj ntau yam zoo, xws li cov qauv ruaj khov, me me, lub teeb yuag, lub neej ntev kev pab cuam, kev co kuj, tsis ntshai plua plav, roj, dej vapor thiab ntsev pos huab los yog corrosion tos.
Thaum lub tshuab magnetic encoder yog siv rau kev sib hloov txoj hauj lwm tawm tswv yim ntawm lub tshuab hluav taws xob, lubsintered NdFeB hlau nplaum lub tog raj kheejntawm qhov sib nqus encoder tuaj yeem ntsia ncaj qha rau ntawm qhov kawg ntawm lub cev muaj zog ncej.Nyob rau hauv txoj kev no, nws tuaj yeem tshem tawm cov kev hloov pauv hloov pauv cov kabmob (lossis sib txuas) yuav tsum tau siv thaum siv cov lus tawm tswv yim ib txwm siv, thiab ua tiav qhov ntsuas qhov tsis sib cuag, uas txo qhov kev pheej hmoo ntawm kev hloov pauv tsis ua haujlwm (lossis txawm tias puas tsuaj) vim yog kev co ntawm lub tshuab ua haujlwm thaum lub sijhawm. kev ua haujlwm ntawm lub tshuab hluav taws xob.Yog li ntawd nws pab txhim kho kev ruaj ntseg ntawm lub tshuab hluav taws xob ua haujlwm.
