Kodi Magnetti a Mphete Amagwiritsidwa Ntchito Bwanji mu Masensa ndi Magnetic Assemblies?

Mukagwira ntchito ndi masensa a maginito, mumazindikira msanga kuti maginito ndi chinthu chosavuta—ndicho chomwe chimapangitsa kuti sensa ikhale yolondola kwa nthawi yayitali ndi yomwe imayamba kuyenda pambuyo pa maginito ochepa chabe.

Maginito a mphete ndi chisankho chofala kwambiri mu mapulogalamu awa, ndipo pachifukwa chabwino. Koma kuwapeza bwino—makamaka mukafuna kupanga—kumafuna zambiri kuposa kungosankha kukula kuchokera pa datasheet.

Ndaona mainjiniya akulemba maginito abwino kwambiri a mphete papepala, koma mavuto ogwirizana nawo adabuka chifukwa mawonekedwe a maginito sanagwirizane ndi momwe sensa imawerengera. Tiyeni tikambirane.mayankho a maginito a mphete a masensa

 

Kutenga Mwachangu

Yabwino kwambiri pa ma encoders ndi masensa a malo
Pamafunika kuwongolera kolondola kwa maginito
Miyeso imakhudza kulondola kwa dongosolo
Kawirikawiri amapangidwa mwamakonda kuti azigwiritsidwa ntchito popanga misonkhano

 

Chifukwa Chake Magnetti a Mphete Amagwiritsidwa Ntchito mu Masensa

Poyamba, maginito ozungulira amawoneka osavuta. Koma pakati pake pali dzenje lomwe limasintha chilichonse.

Munda Wamaginito Wokhazikika

Nayi njira yosinthidwa yomwe imasunga tanthauzo loyambirira pomwe ikusinthasintha kapangidwe ndi mawu:

Poyerekeza ndi maginito olimba a disk, maginito a mphete amapereka ulamuliro wapamwamba komanso kudziwikiratu mphamvu ya maginito. Bore yawo yapakati imalola kufalikira kwa flux kofanana, chinthu chofunikira kwambiri pa masensa a Hall effect ndi zigawo za magnetoresistive zomwe zimafuna kutulutsa kokhazikika komanso kobwerezabwereza.

Mwachitsanzo, mu ma encoder ozungulira, maginito a mphete ya multipole amapanga ma poles osinthasintha kumpoto ndi kum'mwera mozungulira kuzungulira kwake. Sensor imawerenga kusinthaku kuti idziwe malo a angular. Ngati gawolo ndi losafanana, encoder yanu imataya kulondola.

Kuphatikizana Kwakafupikitsa

Malo nthawi zonse amakhala ochepa m'ma sensa. Ndi maginito ozungulira, mutha kuyiyika bwino pa shaft pomwe muli ndi malo mkati mwa zigawo zina. Simukungowonjezera zinthu zina - mukumanga maginitowo mu kapangidwe ka makina.

Ndicho chifukwa chake maginito a mphete amagwiritsidwa ntchito kulikonse—kuyambira masensa oikapo magalimoto m'magalimoto mpaka ma servo motors a mafakitale. Amathetsa vuto la malo oyika popanda kufuna kukonzanso kwathunthu kwa cholumikizira chonsecho.

Pamene pulogalamu ikufuna kugwira ntchito kodalirika pamalo ochepa, mayankho a maginito a mphete a masensa nthawi zambiri amakhala chisankho chothandiza kwambiri.

Mapulogalamu Ofala

Maginito a mphete amapezeka m'malo ambiri kuposa momwe anthu ambiri amaganizira. Nazi zina zomwe specifications zake ndizofunikira.

Olemba ma code

Mu ma encoders a maginito, maginito ozungulira ndi omwe amasintha kayendedwe kozungulira kukhala zizindikiro za digito. Kawirikawiri, maginitowo amakhala ndi maginito ndi ma pole pairs angapo, ndipo sensa imawerengera kusintha kwa maginito pamene akuzungulira.

Vuto apa ndi kulondola kwa maginito. Ngati mitengoyo siili yofanana, mphamvu ya encoder yanu imachepa. Pa ntchito zolondola kwambiri, mukuyang'ana zida zosinthira maginito—osati malo opanda kanthu omwe ali pashelefu.

Machitidwe Odzipangira Okha

Mu mizere yolumikizira yokha, maginito ozungulira amagwiritsidwa ntchito mu machitidwe obwezera malo, malo olumikizirana a robotic, komanso ma switch oteteza maginito. Malo awa ndi osakhululuka. Kugwedezeka, kusintha kwa kutentha, ndi maginito otayika kuchokera ku zida zapafupi zonse zimatha kusokoneza magwiridwe antchito.

Takhala ndi makasitomala osintha maginito a mphete wamba kuti agwiritse ntchito maginito amphamvu kwambiri kuti makina awo akhale olimba pafupi ndi zida zowotcherera. Ndi chimodzi mwa zinthu zomwe sizimawonekera mu gawo la prototype koma zimakhala zofunika kwambiri pamlingo waukulu.

Ngati pali zofunikira zosavuta za axial field,kugwiritsa ntchito maginito ozunguliraamagwiritsidwanso ntchito mobwerezabwereza, makamaka m'masensa ang'onoang'ono komwe kasinthidwe ka mphete sikofunikira.

Mafotokozedwe Ofunika

Tikamalankhula za maginito a mphete a masensa, miyeso itatu ndi yofunika kwambiri kuposa ina iliyonse.

OD / ID / makulidwe

Chimake chakunja chimatsimikizira kuchuluka kwa zinthu zamaginito zomwe muli nazo. Chimake chamkati chimakhudza momwe maginito amamangirira ku shaft. Ndipo makulidwe amakhudza mphamvu ya malo pa mtunda wozindikira wa sensa.

Kumene zinthu zimakhala zovuta ndi ma tolerances. Maginito a mphete omwe ali pa ID sangakhale bwino pa shaft. Ngati ali omasuka, mumataya madzi. Ngati ali olimba kwambiri, mumayika pachiwopsezo chophwanya maginito panthawi yopangira. Nthawi zambiri timaika ma tolerances mpaka ±0.05mm kuti tigwiritse ntchito molondola, ndipo timayang'ana zitsanzo ndi ma caliper tisanavomereze kupanga.

Kukhazikitsa maginito

Apa ndi pomwe ntchito zambiri zauinjiniya zimayendera.

Maginito a mphete amatha kupangidwa ndi maginito m'njira zosiyanasiyana:
- Axial: mitengo pa nkhope zathyathyathya
- Kulowera kwa m'mimba mwake: kumpoto-kum'mwera kudutsa m'mimba mwake
-Mizere yambiri: mitengo yosinthasintha mozungulira

Kwa ma encoders, maginito a multipole ndi okhazikika. Koma kuchuluka kwa ma pole kuyenera kufanana ndi resolution ya sensa. Mphete ya ma pole 32 sigwira ntchito ndi sensa yomwe ikuyembekezera kusintha kwa 16 pa kuzungulira pokhapokha mutasintha firmware kapena signal conditioning.

Tawonanso mapulojekiti akuchedwa chifukwa njira ya maginito sinali yogwirizana ndi momwe sensa imayendera. Ndi tsatanetsatane wosavuta, koma n'zosavuta kuphonya pamene cholinga chili pa miyeso ndi mphamvu yokoka.

 

Zoganizira Zopangira

Kuyitanitsa maginito a mphete kuti agwirizane ndi masensa ndi masewera osiyana ndi kupeza maginito ogwirira ntchito m'sitolo. Kulekerera zolakwika kumakhala kocheperako, ndipo mtengo wolephera umakhala wokwera kwambiri.

Chitsanzo chokhala ndi mikhalidwe yeniyeni yogwirira ntchito

Nthawi zonse timalangiza kuyesa zitsanzo za maginito mu chipinda chenicheni cha sensa, pogwiritsa ntchito zida zamagetsi zowerengera. Magineti yozungulira yomwe imagwira ntchito bwino pa benchi ingachite mosiyana ikayikidwa pafupi ndi mbale zoyikira zitsulo kapena zingwe zamagetsi.

Fotokozani bwino momwe maginito amagwirira ntchito

Chithunzi chojambulidwa ndi miyeso sikokwanira. Muyenera kudziwa kuchuluka kwa mipiringidzo, momwe mipiringidzo imayendera, ndi cholakwika chovomerezeka cha angular. Ngati izi sizinalembedwe, mukusiya malo oti mumasulire—ndipo pamenepo ndi pomwe kusagwirizana kumachitika.

Ganizirani kutentha msanga

Maginito ozungulira okhazikika nthawi zambiri amasunthira ku N35SH kapena magiredi ofanana ndi kutentha kwambiri akapitirira 80°C. Ngati sensa yanu yayikidwa pafupi ndi mota kapena mu bay ya injini, N42 yomwe inali yokwanira kupanga prototyping ingalephereke chifukwa cha kupsinjika kwa kupanga.

Funsani mafunso oyenera

Wopereka maginito wabwino adzakufunsani za mtundu wa sensa yanu, njira yoyikira, ndi malo ogwirira ntchito. Ngati satero, ndiye kuti ndi chizindikiro choopsa. Opanga adatiuza kuti "ndi maginito ozungulira" mpaka titayamba kugwiritsa ntchito pulogalamuyi ndikupeza kuti amafunikira maginito ochulukitsa ndi ±2-degree molondola.

 

Zinthu Zing'onozing'ono Zoti Muziyang'anira

Kusamalira ndi kusunga
Maginito a mphete—makamaka mainchesi akuluakulu—akhoza kukhala amphamvu modabwitsa. Tawaona akulumikizana kuchokera patali mamita angapo, kuwononga maginito onse ndi aliyense wapafupi. Kuti mudziwe kuchuluka kwa kupanga, ndikofunikira kukonzekera momwe adzagwiritsidwire ntchito ndi maginito akadzapangidwa.

Zosankha zokutira
Kupaka nickel ndi chisankho chachizolowezi, koma ngati chipangizo chanu cha sensor chili ndi chinyezi, kupopera mchere, kapena mankhwala oyeretsera, mwina mungafunike epoxy kapena rabara. Tinapeza izi titasintha gulu lokhala ndi dzimbiri—miyezi isanu ndi umodzi yokha yogwiritsidwa ntchito panja.

Magnetization itatha msonkhano
Pa mphete zambirimbiri, nthawi zina zimakhala bwino kugwiritsa ntchito maginito pambuyo poti maginito ayikidwa mu assembly. Izi zimapewa mavuto olumikizana panthawi yotumiza ndikuwonetsetsa kuti zipilala zili pamalo omwe ziyenera kukhala poyerekeza ndi sensa.

 

Maganizo Omaliza

Maginito a mphete ndi gawo laling'ono la sensa, koma si chinthu chofunika kwambiri. Kusiyana pakati pa sensa yomwe imagwira ntchito bwino ndi yomwe imalephera kugwira ntchito nthawi zambiri kumadalira momwe maginitoyo adafotokozedwera bwino—ndi ngati njira yopangira idakwaniritsadi zomwe zidapangidwa.

Ngati mukufuna kupanga, tengani nthawi yoyesa mawonekedwe a maginito, kutsimikizira kukula kwake, ndikufananiza giredi ya maginito ndi malo omwe mukugwira ntchito. Khama lanu loyamba limapindula nthawi yoyamba mukatumiza batch popanda kulephera kwa malo.
