Ib qho incremental encoder yog ib qho khoom siv encoder uas hloov lub angular motion lossis txoj hauj lwm ntawm ib tug ncej rau hauv ib qho analog los yog digital code los txheeb xyuas txoj haujlwm lossis kev txav mus los. Incremental encoders yog ib qho ntawm feem ntau siv teb encoders. Incremental encoders tuaj yeem siv rau hauv qhov chaw thiab lub cev muaj zog tawm tswv yim daim ntawv thov suav nrog servo / lub teeb, kev lag luam lossis cov ntawv thov hnyav. Incremental encoders muab kev ceev ceev thiab kev tawm tswv yim nyob deb, thiab vim tias muaj ob peb lub sensors koom nrog, lub kaw lus yooj yim thiab pheej yig. Incremental encoders tsuas yog muab cov ntaub ntawv hloov pauv, yog li cov encoders xav tau cov cuab yeej siv los xam cov lus tsa suab.
1. Incremental encoders ua haujlwm li cas? Yuav ua li cas Incremental Encoders ua haujlwm!
Incremental encoders muab ib tus naj npawb ntawm pulses thaum lub sij hawm ib tug encoder kiv puag ncig. Cov zis tuaj yeem yog ib kab ntawm pulses ("A" channel) lossis ob kab ntawm pulses ("A" thiab "B" channel), uas yog offset los txiav txim kev sib hloov. Cov theem no ntawm ob lub teeb liab hu ua quadrature. Nyob rau hauv incremental optical encoders, ib tug raug sib dhos muaj ib tug spindle los ua ke, ib tug PCB thiab ib lub hau. PCB muaj ib qho ntawm cov sensors uas tsim tsuas yog ob lub cim tseem ceeb rau txoj hauj lwm thiab kev tshaj tawm.
Nrog incremental optical encoders, lub optical sensor pom lub teeb thaum nws dhau los ntawm cov cim disc. Lub disc txav raws li qhov sib dhos spindle tig, thiab cov ntaub ntawv tau hloov mus rau hauv pulses los ntawm PCB. Rau incremental magnetic encoders, optical sensor yog hloov los ntawm ib tug sib nqus sensor, thiab rotating disk muaj ib tug series ntawm magnetic ncej.
Optionally, cov teeb liab ntxiv tuaj yeem muab:
Qhov Performance index lossis "Z" channel tuaj yeem muab tau raws li cov mem tes ib lub kiv puag ncig rau homing thiab pulse suav txheeb xyuas ntawm A thiab / lossis B raws. Qhov ntsuas no tuaj yeem raug gated nyob rau hauv ntau lub xeev ntawm A lossis B. Nws tuaj yeem ua tsis tau gated thiab muaj qhov dav sib txawv. Qee tus encoders tseem tuaj yeem muab kev sib hloov (U, V, W) raws. Cov teeb liab no sib txuas nrog kev sib hloov windings ntawm servo lub cev muaj zog. Lawv kuj xyuas kom meej tias cov tsav tsheb lossis lub tshuab hluav taws xob ntawm cov motors siv tam sim no rau txhua qhov cua hauv qhov kev txiav txim kom raug thiab nyob rau theem raug.
2. Cov khoom dab tsi tuaj yeem hloov pauv hloov pauv nrog ib leeg?
Thaum incremental encoders feem ntau siv nyob rau hauv ntau daim ntawv thov kev tawm tswv yim, cov kev daws teeb meem thiab cov encoders kiag li muaj lwm txoj hauv kev nyob ntawm daim ntawv thov thiab ib puag ncig.
* Incremental encoder thiab parser
Resolvers yog electromechanical precursors rau encoders, raws li cov cuab yeej yos rov qab rau Ntiaj Teb Tsov Rog II. Qhov tam sim no tsim ib qho chaw sib nqus raws qhov chaw winding. Muaj ob txoj kev sib tshuam perpendicular windings. Ib qho winding yog tsau rau hauv qhov chaw thiab lwm qhov winding txav raws li cov khoom txav. Cov kev hloov ntawm lub zog thiab txoj hauj lwm ntawm ob qhov sib cuam tshuam magnetic teb tso cai rau tus neeg daws teeb meem los txiav txim qhov kev txav ntawm cov khoom.
Qhov yooj yim ntawm kev daws teeb meem tsim tso cai rau nws ua haujlwm ntseeg tau txawm tias nyob rau hauv cov xwm txheej huab cua, los ntawm qhov kub thiab txias qhov kub thiab txias mus rau hluav taws xob raug hluav taws xob thiab txawm tias muaj kev cuam tshuam los ntawm kev co thiab kev poob siab. Txawm li cas los xij, parser qhov kev zam txim ntawm qhov chaw thiab daim ntawv thov sib sau ua ke los ntawm kev siv nyiaj ntawm lawv lub peev xwm los ua haujlwm hauv cov ntawv thov nyuaj, vim nws tsis tuaj yeem tsim cov ntaub ntawv raug txaus. Tsis zoo li incremental encoders, cov neeg daws teeb meem tsuas yog tso tawm cov ntaub ntawv analog, uas yuav xav tau cov khoom siv hluav taws xob tshwj xeeb rau kev sib tshuam.
* Incremental encoder thiab absolute encoder
Cov encoders kiag li ua haujlwm qhov twg qhov nrawm thiab qhov tseeb ntawm txoj haujlwm, kev ua txhaum cai thiab kev sib cuam tshuam yog qhov tseem ceeb tshaj qhov system simplicity. Tus encoder kiag li muaj peev xwm "paub qhov twg nws yog" raws li nws txoj hauj lwm nyob rau hauv cov kev tshwm sim ntawm ib tug system fais fab tuag, thiab rov pib dua yog hais tias tus encoder txav thaum lub sij hawm qhov hluav taws xob.
Lub encoder kiag li nws tus kheej paub qhov chaw cov ntaub ntawv - nws tsis tas yuav cia siab rau sab nraud electronics los muab ib tug hauv paus Performance index ntawm lub encoder txoj hauj lwm. Tshwj xeeb tshaj yog piv rau cov kev daws teeb meem thiab incremental encoders, qhov kom zoo dua ntawm cov encoders kiag li yog li cas lawv qhov chaw raug cuam tshuam rau tag nrho daim ntawv thov kev ua tau zoo, yog li nws feem ntau yog tus encoder ntawm kev xaiv rau high-precision daim ntaub ntawv xws li CNC, kho mob, thiab neeg hlau.
3. Kev siv thiab kev siv ntawm incremental encoder
Incremental encoders yog tsim los ua ntau yam thiab kho kom haum rau ntau yam kev siv. Peb qhov dav ntawm cov ntawv thov raws li ib puag ncig yog:
* Hnyav Hnyav: Ib puag ncig hnyav nrog lub peev xwm loj rau kev sib kis thiab ya raws, kub siab dua, kev poob siab thiab kev vibration, raws li pom nyob rau hauv pulp, ntawv, steel thiab lumber mills.
* Cov ntawv thov kev lag luam: Cov chaw tsim khoom lag luam dav dav uas yuav tsum tau ntsuas tus qauv IP, nruab nrab poob siab, kev vibration thiab kub specifications raws li pom nyob rau hauv cov zaub mov thiab dej haus, textile, general Hoobkas automation factories.
* Lub teeb yuag / Servo: Tswj ib puag ncig nrog siab precision thiab kub yuav tsum tau, xws li robotics, electronics, thiab semiconductors.
