Mbiri ndi Mbiri

Amaginito okhazikika ndi gawo lofunikira m'moyo wamakono. Zimapezeka kapena kugwiritsidwa ntchito kutulutsa pafupifupi chilichonse chamakono chomwe chilipo masiku ano. Maginthi oyamba okhazikika anapangidwa kuchokera ku miyala yomwe imakhalapo mwachilengedwe yotchedwa ma lodestones. Miyala iyi idaphunziridwa koyamba zaka 2500 zapitazo ndi aku China ndipo kenako Agiriki, omwe adalandira mwalawo kuchokera ku chigawo cha Magnetes, pomwe zidatchulidwapo dzina. Kuyambira pamenepo, mphamvu zamagetsi zakhala zikusinthidwa kwambiri ndipo masiku ano zida zamagetsi zokhazikika zimakhala zamphamvu kwambiri nthawi zambiri kuposa mphamvu zamagetsi. Mawu akuti maginito osatha amachokera ku mphamvu ya maginito kugwira mphamvu ya maginito atachotsedwa mu chida cha maginito. Zipangizo zoterezi zimatha kukhala zamagetsi zamagetsi zamagetsi, malekitro-ma waya kapena waya wama waya amene amamangidwa mwachidule ndi magetsi. Mphamvu yawo yokhala ndi maginito opangira magetsi imawapangitsa kukhala othandiza kusunga zinthu m'malo mwake, kusintha magetsi kukhala mphamvu yamagetsi ndi motsutsana (ma motors ndi ma jenereta), kapena kukhudza zinthu zina zomwe zimabweretsedwa pafupi nawo.

Design

Kuchita zamagetsi kwamphamvu kwambiri ndi ntchito yamaukina apamwamba. Kwa makasitomala omwe amafunikira thandizo lakapangidwe kapangidwe kovuta Ma QM Gulu la akatswiri odziwa ntchito komanso mainjiniya odziwa ntchito azogulitsa ali pantchito yanu. QM mainjiniya amagwira ntchito ndi makasitomala kukonza kapena kutsimikizira mapangidwe omwe alipo komanso kupanga zolemba zapamwamba zomwe zimatulutsa mphamvu zapadera zamatsenga. QM amakonza maginito okhala ndi mapepala okhala ndi maginito amphamvu kwambiri, ofunikira kapena opangidwa mwapadera kwambiri omwe nthawi zambiri amasintha maginito opangira magetsi osakwanira komanso osakwanira. Makasitomala amakhala ndi chidaliro pamene hey amabweretsa lingaliro lovuta kapena lingaliro latsopano lomwe QM adzakumana ndi vuto lojambula kuyambira zaka 10 zaukatswiri wamatsenga wotsimikizika. QM ali ndi anthu, zogulitsa ndi ukadaulo zomwe zimapangitsa maginito kugwira ntchito.

Kusankha Magnet

Kusankhidwa kwa magnet pazogwiritsira ntchito zonse kuyenera kuganizira maginito onse ndi chilengedwe. Komwe kuli Alnico koyenera, kukula kwa maginito kumatha kuchepetsedwa ngati kungakhale maginito mutatha maginito. Ngati amagwiritsidwa ntchito mosayimira mbali zina za dera, monga momwe amagwiritsidwira ntchito pochita chitetezo, kutalika koyenera mpaka m'mimba mwake (kogwirizana ndi kuchuluka kwa purifesiti) kuyenera kukhala kokwanira kuchititsa kuti maginito azigwira ntchito pamwamba pa bondo pamagawo ake achiwiri. Pakugwiritsa ntchito zovuta, maginito a Alnico akhoza kuwerengeredwa pamtengo wokhazikitsidwa ndi mtundu wa fluxensens.

Choyambitsa chochitika chochepa kwambiri ndikuzindikira mphamvu zowonongeka chifukwa champhamvu yamagetsi yakunja, kugwedezeka, ndi kutentha kwa ntchito. Pakugwiritsa ntchito zovuta, maginito a Alnico amatha kukhala otentha kuti muchepetse izi Pali magawo anayi a maginito amakono ogulitsa, aliwonse kutengera momwe amapangira. Mkalasi lililonse muli banja lamakalasi okhala ndi maginito awo. Maphunziro awa ndi awa:

  • Neodymium Iron Boron
  • Samarium Cobalt
  • ceramic
  • Alnico

NdFeB ndi SmCo onse amadziwika kuti Rare Earth maginito chifukwa onsewa amapangidwa ndi zinthu kuchokera ku gulu la zinthu za Rare Earth. Neodymium Iron Boron (wophatikizika Nd2Fe14B, yemwe nthawi zambiri amafupikitsidwa ku NdFeB) ndiye malonda omwe amapezeka posachedwa kwambiri kwa banja la zida zamakono zamagetsi. Kutentha kwa firiji, maginito a NdFeB amawonetsera zida zapamwamba kwambiri zamagetsi. Samarium Cobalt amapangidwa m'mitundu iwiri: Sm1Co5 ndi Sm2Co17 - nthawi zambiri amatchedwa Mitundu ya SmCo 1: 5 kapena SmCo 2:17. Mitundu ya 2:17, yokhala ndi mfundo zapamwamba za Hci, imapereka kukhazikika kwakukulu kuposa mitundu 1: 5. Ceramic, yomwe imadziwikanso kuti Ferrite, maginito (general composition BaFe2O3 kapena SrFe2O3) akhala akugulitsa kuyambira m'ma 1950 ndipo akupitilizabe kugwiritsidwa ntchito kwambiri masiku ano chifukwa cha mtengo wawo wotsika. Fomu yapadera yamagalasi a Ceramic ndi zinthu "Zosasinthika", zopangidwa ndi kulumikiza Ceramic ufa mu binder yosinthika. Maginito a Alnico (gulu lonse la Al-Ni-Co) adagulitsidwa mu 1930s ndipo akugwiritsidwabe ntchito masiku ano.

Zipangizozi zimakhala ndi malo osiyanasiyana omwe zimakhala ndi mitundu yambiri ya zofunikira pakugwiritsa ntchito. Chotsatirachi chikupereka chiwonetsero chachikulu koma chothandiza pazinthu zomwe ziyenera kulingaliridwa posankha zinthu zoyenera, kalasi, mawonekedwe, ndi kukula kwa maginito pa ntchito inayake. Tchati chili pansipa chikuwonetsa zofunikira pazomwe zimasankhidwa pazopanga zamitundu yosiyanasiyana poyerekeza. Mfundo izi zikambidwa mwatsatanetsatane m'magawo otsatirawa.

pamwamba Chithandizo

Ma magneti angafunikire kuti azilimbilidwa kutengera kutengera komwe akukonzera. Maginito othandiza kupangira bwino kumawongolera maonekedwe, kukana kwa kutu, kutetezedwa pakuvala ndipo kungakhale koyenera kwa mapulogalamu mu chipinda choyera.
Samarium Cobalt, Zipangizo za Alnico sizogwirizana ndi dzimbiri, ndipo sizikufunika kuti mutenthe polimbana ndi kutu. Alnico amapangidwa mosavuta pazikhalidwe zodzikongoletsera.
Amaginito a NdFeB makamaka amatha kugwidwa ndi dzimbiri ndipo nthawi zambiri amatetezedwa motere. Pali mitundu ingapo ya zokutira yoyenera maginito okhazikika, Osati mitundu yonse ya zokutira idzakhala yoyenera pazinthu zilizonse kapena ma geometry a maginito, ndipo kusankha komaliza kumadalira ntchito ndi chilengedwe. Njira ina ndikuyika maginito mumtundu wakunja kuti dzimbiri zisawonongeke.

Maginito

Maginito okhazikika omwe amaperekedwa pazochitika ziwiri, Magnetized kapena alibe maginito, nthawi zambiri samadziwika kuti ndi abwino. Wogwiritsa ntchito atafuna, titha kuzindikira kuti ndife osiyana ndi omwe tikugwirizana nawo. Posankha lamulolo, wogwiritsa ntchito azidziwitsa mawonekedwe ake ndikuwonetsa ngati polarity ikufunika.

Mphamvu yamagetsi yamagalasi yokhazikika imayenderana ndi mtundu wamtundu wanthawi zonse wazinthu zamagetsi komanso mphamvu yake yolimba. Ngati maginito amafunikira mphamvu ya maginito ndi demagnetization, chonde lemberanani ndi ife ndikupempha thandizo.

Pali njira ziwiri zopangira mphamvu zamagetsi: Gawo la DC ndi kukoka maginito.

Pali njira zitatu zotsitsira mphamvu yamagetsi: demagnetization ndi kutentha ndi njira ina yapadera. demagnetization m'munda wa AC. Demagnetization m'munda wa DC. Izi zimapempha mphamvu yamphamvu kwambiri yamagetsi komanso luso lapamwamba la demagnetization.

Mawonekedwe a geometry ndi mayendedwe a maginito a maginito osatha: makamaka, timatulutsa maginito osatha mosiyanasiyana. Nthawi zambiri, zimaphatikizapo block, disc, mphete, gawo etc. Chithunzi chatsatanetsatane cha mayendedwe a maginito ndi pansipa:

Mfundo zoyendetsera chitetezo pamanja

1. Maginito osatha okhala ndi maginito amphamvu amakopa zitsulo ndi zinthu zina zamagalasi kuzungulira kwambiri. Pazinthu zodziwika bwino, wothandizirayo akuyenera kusamala kuti asawonongeke. Chifukwa cha mphamvu yamphamvu ya maginito, maginito akulu okhala nawo pafupi amakhala pachiwopsezo cha kuwonongeka. Anthu nthawi zonse amakonzera izi padera kapena pandalama. Pankhaniyi, tiyenera kusula magolovesi achitetezo akugwira ntchito.

2. Panthawi imeneyi ya maginito amphamvu, gawo lililonse lamagetsi lamagetsi komanso mita yoyeserera imatha kusintha kapena kuwonongeka. Chonde onetsetsani kuti kompyuta, zowonetsera ndi maginito wamagetsi, mwachitsanzo maginito a maginito, makaseti azamatsenga ndi makanema ojambulira ndi zina zotere, ndizakutali kwambiri ndi maginito, tinene kutali kuposa 2m.

3. Kugundana kwa mphamvu yokoka pakati pamagetsi awiri okhazikika kumabweretsa kubwera kwakukulu. Chifukwa chake, zinthu zoyaka kapena zophulika siziyenera kuyikidwa mozungulira iwo.

4. Maginito ikavulazidwa ndi hydrogen, ndizoletsedwa kugwiritsa ntchito maginito osakhazikika osateteza. Cholinga chake ndikuti kunenepa kwa haidrojeni kudzawononga mphamvu ya maginito ndikupangitsa kuti mphamvu zamatsenga zizipangidwanso. Njira yokhayo yotetezera maginitoyo ndikutchingira maginito muja ndikusindikiza.
