Magnetti eRin'i Anoshandiswa Sei muSensors neMagnetic Assemblies?

Kana washanda nemasensa emagineti, unokurumidza kuona kuti magineti haisi chinhu chiri nyore—ndiyo inosarudza pakati pesensa inochengetedza kururama kwayo kwenguva refu uye iyo inotanga kufamba mushure mezviuru zvishoma zvemasensa.

Magineti emhete anowanzo shandiswa muzvirongwa izvi, uye nechikonzero chakanaka. Asi kuagadzira nemazvo—kunyanya paunenge uchitsvaga zvekugadzira—hazvingodi kungosarudza saizi kubva papepa redata.

Ndakaona mainjiniya vachitsanangura magineti erin'i akakwana papepa, asi vakazosangana nematambudziko ekubatanidza nekuti pateni yemagnetization haina kufanana nepfungwa yekuverenga yesensor. Ngatifambei tichitarisa.mhinduro dzemagineti emhete dzemasensa

 

Kutora Nekukurumidza

Yakanakira ma encoders uye masensa enzvimbo
Inoda kutonga kwakarurama kwemagnetization
Zviyero zvinokanganisa kururama kwehurongwa
Kazhinji inogadzirwa kuti ishandiswe pamisangano

 

Nei Magnetti eRing Achishandiswa muSensors

Pakutanga, magineti yerin'i inoita kunge iri nyore. Asi pakati payo pakaita gomba rinochinja zvese.

Munda weMagineti Wakagadzikana

Heino shanduro yakadzokororwa inoramba iine zvarinoreva pakutanga uku ichichinja chimiro nemashoko:

Kana tichienzanisa nemagineti edhisiki yakasimba, magineti erin'i anopa kutonga kwepamusoro uye kufanotaura simba remagineti. Bore rawo repakati rinogonesa kugoverwa kweflux kwakaenzana, chinhu chakakosha kune maHall effect sensors uye zvikamu zvemagnetoresistive zvinoda kubuda kwakasimba uye kunodzokororwa.

Semuenzaniso, muma "rotary encoders", magineti ane "multipole ring magnet" anogadzira "alternate poles" kubva kuNorth kusvika kuSouth poles achitenderedza denderedzwa rayo. Sensor inoverenga shanduko idzi kuti ione nzvimbo ye "angular". Kana nzvimbo yacho isina kuenzana, "encoder" yako inorasikirwa nekururama.

Kubatanidzwa Kwakakwana

Nzvimbo inogara isina chinhu mumasensa akabatanidzwa. Uchishandisa ring magnet, unogona kuiisa pashaft uchine nzvimbo mukati mezvimwe zvikamu. Hausi kungowedzera zvinhu chete—uri kuvaka magnet muchimiro chemuchina.

Ndosaka magineti ering achishandiswa kwese kwese—kubva kumasensa e throttle position mumota kusvika kuma industrial servo motors. Anogadzirisa dambudziko rekuisa mota pasina kuda kugadziriswa kwakazara kwechikamu chose.

Kana application ichida kushanda kwakavimbika munzvimbo diki, mhinduro dzemagineti ering dzemasensa kazhinji ndiyo sarudzo inonyanya kushanda.

Maitiro Akajairika

Magineti eringi anowanikwa munzvimbo dzakawanda kupfuura vanhu vazhinji vanoziva. Heano mashoma apo magadzirirwo acho anonyanya kukosha.

Makodhi

Muma encoders emagineti, magineti erin'i ndiwo anoshandura kufamba kwese kwese kuita masaini edhijitari. Kazhinji, magineti ane magineti ane mapeya akati wandei, uye sensor inoongorora kushanduka kwegineti painotenderera.

Dambudziko riripo pano nderekunyatsoshanda kwemagnetization. Kana matanda asina kuenzana, resolution ye encoder yako inoderera. Kune maapplication akanyatsogadzirwa, uri kutarisa ma custom magnetization fixtures—kwete ma blanks asina kugadzirwa.

Masisitimu Ekushandisa Otomatiki

Mumitsetse yekubatanidza otomatiki, magineti erin'i anoshandiswa muzvirongwa zvekupa mhinduro panzvimbo, marobhoti, uye kunyange maswichi ekuchengetedza emagineti. Nzvimbo idzi hadzina kukanganwira. Kudedera, kushanduka kwekushisa, uye simba remagineti rinobva mumidziyo iri pedyo zvinogona kukanganisa mashandiro.

Tave nevatengi vachichinja magineti ering akajairwa kuti vagadzire magadzirirwo emagetsi anochinjika zvakanyanya kuitira kuti masisitimu avo agare akasimba pedyo nemidziyo yekuwelda. Ndiwo mumwe wezvinhu zvisingaonekwe muchikamu chemuenzaniso asi zvinova zvakakosha pakukura.

Kana paine zvinodiwa zviri nyore zve axial field,mashandisirwo emagineti e cylindricalanoshandiswawo kakawanda, kunyanya mumasensa madiki uko kunenge kusina kurongwa kweringi.

Magadzirirwo Akakosha

Kana tichitaura nezvemagineti emhete emasensa, mativi matatu anokosha kupfuura mamwe ese.

OD / ID / ukobvu

Dhayamita yekunze ndiyo inosarudza kuti une magineti akawanda sei. Dhayamita yemukati inokanganisa kuti magineti inokwira sei kushaft. Uye ukobvu hunokanganisa simba remunda padanho rekuona sensor.

Zvinhu zvinonetsa ndezviya zvekutenderwa. Magineti yerin'i inenge isina simba paID haigari zvakanaka pashaft. Kana yakasununguka, unorasikirwa nesimba. Kana yakanyanya kuoma, unogona kutyora magineti panguva yekubatanidza. Tinowanzo tsanangura matenderi kusvika ±0.05mm kuti tiwane mashandisirwo akarurama, uye tinotarisa sampuro nemacaliper tisati tabvumidza kugadzirwa.

Kugadzira magineti

Apa ndipo panonyanya kushanda nesimba reinjiniya.

Magineti emhete anogona kugadzirwa nemagineti nenzira dzakasiyana:
- Axial: matanda ari pazviso zvakati sandara
- Dhayamita yakanangana: kuchamhembe-kumaodzanyemba mhiri kwedhayamita
-Nzvimbo dzakawanda: matanda anochinjana akatenderedza denderedzwa

Kune vanoisa maencoder, multipole magnetization ndiyo yakajairika. Asi huwandu hwepole hunofanirwa kuenderana ne resolution ye sensor. Ring ye 32-pole haizoshande ne sensor inotarisira shanduko gumi nematanhatu pa revolution kunze kwekunge wagadzirisa firmware kana signal conditioning.

Taonawo mapurojekiti achinonoka nekuti divi remagnetization rakanga risingaenderane nekwaishandiswa ne sensor. Chinhu chiri nyore, asi zviri nyore kupotsa kana tichitarisa pahukuru uye simba rekudhonza.

 

Zvaunofanira Kufunga Nezvekugadzira

Kuraira magineti ering ekubatanidza masensa mutambo wakasiyana nekutsvaga magineti ekubata pasi pechitoro. Kushivirira kukanganisa kwakaoma zvikuru, uye mutengo wekukundikana unowanzo kuve wakakwira zvakanyanya.

Muenzaniso une mamiriro chaiwo ekushanda

Tinogara tichikurudzira kuyedza masampuli emagineti mukamuri remasensa chaiwo, nemagetsi chaiwo ekuverenga. Magneti yerin'i inoshanda zvakanaka pabhenji inogona kuita zvakasiyana kana yaiswa pedyo nemapurati esimbi kana tambo dzemagetsi.

Taura zvakajeka maitiro emagnetization

Kudhirowa kwakaenzana hakukwani. Unofanira kutsanangura huwandu hwemapango, kurongeka kwemapango, uye kukanganisa kwemakona kunotenderwa. Kana izvi zvisina kunyorwa, uri kusiya mukana wekududzira—uye ndipo panoitika kusawirirana.

Funga nezvekupisa nekukurumidza

Magineti eringi akajairika anowanzo famba kuenda kuN35SH kana mamwe magiredhi akafanana ekupisa kwepamusoro kana nharaunda yadarika 80°C. Kana sensor yako yakaiswa pedyo nemota kana mu engine bay, N42 yakakwana yekugadzira ma prototyping inogona kutadza kushanda kana paine kushushikana kwekugadzirwa.

Bvunza mibvunzo chaiyo

Mutengesi wemagineti akanaka achakubvunza nezverudzi rwesensor yako, nzira yekuiisa, uye nzvimbo yekushanda. Kana vakasadaro, izvozvo zvinoratidza kuti hazvina kunaka. Vagadziri vakatiudza kuti "ingori ring magnet" kusvika tapedza kushandisa magineti uye tazoona kuti vaida multipole magnetization ine ±2-degree accuracy.

 

Zvinhu Zvishoma Zvekutarisira

Kubata nekuchengetedza
Magineti erin'i—kunyanya dhayamita hombe—anogona kunge akasimba zvinoshamisa. Takaona achibatana ari kure nemamita akati wandei, zvichikuvadza magineti acho nemunhu wese ari pedyo. Kuti tizive huwandu hwemagadzirwo acho, zvakakosha kuronga kuti achabatwa sei uye achaiswa sei magineti mushure mekuungana.

Sarudzo dzekuputira
Kuisa nickel plating isarudzo yakajairika, asi kana sensor assembly yako ikasangana nehunyoro, munyu, kana makemikari ekuchenesa, ungangoda epoxy kana rabha coating. Takazviwana mushure mekutsiva batch yakaora - mwedzi mitanhatu chete yatanga kushandiswa munzvimbo yekunze ye automation.

Magnetization mushure mekuungana
Kune ma rings e multipole, dzimwe nguva zviri nani kuisa magineti mushure mekunge magineti aiswa mu assembly. Izvi zvinodzivirira matambudziko ekuenderana panguva yekutumira uye zvinoita kuti matanda acho ave panzvimbo chaiyo yaanofanira kunge ari kana tichienzanisa ne sensor.

 

Pfungwa Dzekupedzisira

Magineti erin'i chikamu chidiki chesensa, asi haasi chinhu chakakosha. Musiyano uripo pakati pesensa inoshanda zvakanaka neinokundikana mubasa unowanzoenderana nekuti magineti acho akanyatsotsanangurwa here—uye kana maitiro ekugadzira akazadzisa zvakagadzirwa.

Kana uri kutsvaga nzira yekugadzira, tora nguva yekuedza maitiro emagnetization, ongorora saizi, uye enzanisa giredhi remagnet nemamiriro ekushanda kwako. Kuedza kwekutanga kunobhadhara kekutanga paunotumira batch isina kutadza kushanda.
