Kusankha maginito oyenera
Kusankha njira yoyenera ya maginito pakugwiritsa ntchito kwanu kungakhale kovuta. Pali mitundu yosiyanasiyana ya zida za maginito zomwe mungasankhe, chilichonse chimakhala ndi machitidwe osiyanasiyana. Monga katswiri wothandizira maginito, ndi zomwe takumana nazo mu maginito, titha kukuthandizani kuti mupange chisankho choyenera.
Zida zosiyanasiyana zilipo, kuphatikiza maginito a neodymium (NdFeB kapena rare earth), maginito a alnico (AlNiCo), samarium cobalt (SmCo) kapena maginito a ferrite (ceramic). Kuphatikiza apo, pali mitundu yosiyanasiyana monga ma electromagnets, maginito osinthika ndi maginito omangika. Kusankha zinthu zoyenera ndiye chinsinsi cha ntchito yopambana.
Pali mitundu ingati ya maginito
Gulu losavuta la maginitowa likhoza kupangidwa pogwiritsa ntchito maginito osiyanasiyana komanso gwero la maginito awo. Maginito omwe amakhalabe maginito pambuyo pa magnetization amatchedwa maginito okhazikika. Chosiyana ndi ichi ndi electromagnet. Maginito amagetsi ndi maginito osakhalitsa omwe amangokhala ngati maginito osatha akakhala pafupi ndi maginito, koma amataya izi mwachangu akachotsedwa.
Maginito osatha nthawi zambiri amagawidwa m'magulu anayi malinga ndi zida zawo: NdFeB, AlNiCo, SmCo ndi ferrite.
Neodymium iron boron (Ndi FeB) - omwe amadziwika kuti neodymium iron boron kapena NEO maginito - ndi maginito osowa padziko lapansi opangidwa ndi alloying neodymium, iron ndi boron, ndipo ndi maginito amphamvu kwambiri omwe alipo masiku ano. Kumene, NdFeB akhoza kugawidwa mu sintered NdFeB, womangidwa NdFeB, psinjika jekeseni NdFeB ndi zina zotero. Komabe, zambiri, ngati sitifotokoza mtundu wanji wa Nd-Fe-B, tidzanena za sintered Nd-Fe-B.
Samarium Cobalt (SmCo) - yomwe imadziwikanso kuti rare earth cobalt, rare earth cobalt, RECo ndi CoSm - sizolimba ngati maginito a neodymium (NdFeB), koma amapereka maubwino atatu akuluakulu. Maginito opangidwa kuchokera ku SmCo amatha kugwira ntchito pa kutentha kwakukulu, kukhala ndi kutentha kwapakati komanso kugonjetsedwa ndi dzimbiri. Chifukwa SmCo ndiyokwera mtengo kwambiri ndipo ili ndi zinthu zapaderazi, SmCo imagwiritsidwa ntchito nthawi zambiri pazankhondo komanso zamlengalenga.
Aluminium-Nickel-Cobalt (AlNiCo) - Zida zonse zitatu za AlNiCo - aluminiyamu, faifi tambala ndi cobalt. Ngakhale kuti ndi zolimbana ndi kutentha, zimakhala zosavuta kuzimitsa maginito. Muzinthu zina, nthawi zambiri amasinthidwa ndi maginito a ceramic ndi osowa padziko lapansi. AlNiCo nthawi zambiri imagwiritsidwa ntchito m'moyo watsiku ndi tsiku poyima ndi kuphunzitsa.
Ferrite- Maginito okhazikika a ceramic kapena ferrite nthawi zambiri amapangidwa kuchokera ku sintered iron oxide ndi barium kapena strontium carbonate ndipo ndi otsika mtengo komanso osavuta kupanga poyimitsa kapena kukanikiza. Iyi ndi imodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri ndi maginito. Iwo ndi amphamvu ndipo mosavuta demagnetized.
Maginito osatha akhoza kugawidwa m'magulu otsatirawa kupyolera mu kusiyana kwa mitundu yosiyanasiyana:
Sintering - ndikusintha kwa zinthu za ufa kukhala matupi owundana ndipo ndi njira yachikhalidwe. Anthu akhala akugwiritsa ntchito ndondomekoyi kwa nthawi yaitali kuti apange zoumba, ufa zitsulo, zipangizo zowonongeka, zipangizo zotentha kwambiri, ndi zina zotero. opangidwa ndi makristasi, vitreous humor ndi pores. Njira yopangira sintering imakhudza mwachindunji kukula kwa mbewu, kukula kwa pore ndi mawonekedwe ndi kugawa malire a tirigu mu microstructure, zomwe zimakhudzanso zinthu zakuthupi.
Kumanga - Kumangirira si mtundu wapadera kwambiri wa mawuwa, chifukwa kugwirizana ndiko kumangirira zinthu zomata pamodzi pogwiritsa ntchito zomatira. Mwanjira imeneyi mafunde a eddy omwe amapangidwa pakugwiritsa ntchito maginito amatha kuchepetsedwa pang'ono, ndikuwongolera kudalirika kwa maginito pakugwiritsa ntchito.
Kumangirira jekeseni - Kuumba jekeseni ndi njira yopangira mawonekedwe azinthu zamakampani. Zogulitsa nthawi zambiri zimawumbidwa pogwiritsa ntchito jakisoni wa mphira ndi jekeseni wa pulasitiki. jekeseni akamaumba akhoza kugawidwa mu jekeseni akamaumba njira ndi kufa kuponyera njira. Kugwiritsa ntchito jekeseni ngati njira yopangira kungapereke mwayi wochuluka wa maonekedwe a maginito. Chifukwa cha mphamvu ya maginito okha, maginito a sintered nthawi zambiri amakhala osasunthika komanso ovuta kupanga mawonekedwe enieni. Njira yopangira jakisoni nthawi zambiri imapangitsa kuti mawonekedwe ambiri atheke pophatikiza zida zina.
Flexible Magnet- Maginito osinthika ndi maginito omwe amatha kupindika ndikupunduka ndipo maginito ake amakhalabe. Maginitowa nthawi zambiri amapangidwa ndi zinthu zosinthika, monga mphira, polyurethane, etc., ndipo amasakanizidwa ndi maginito ufa kuti apange maginito. Mosiyana ndi maginito olimba achikhalidwe, maginito osinthika amakhala osinthika komanso osinthika, kotero amatha kudulidwa ndi kupindika mosiyanasiyana ngati pakufunika. Amakhalanso ndi zinthu zabwino zomatira ndipo atha kugwiritsidwa ntchito ngati a
Solenoid: Chosiyana ndi maginito okhazikika ndi electromagnet, yomwe imatha kutchedwanso maginito osakhalitsa. Maginito amtundu uwu ndi koyilo yomwe imapanga lupu pomangirira mawaya mozungulira chinthu chapakati, chomwe chimadziwikanso kuti solenoid. Podutsa magetsi kudzera mu solenoid, mphamvu ya maginito yomwe imagwiritsidwa ntchito popanga maginito a electromagnet imapangidwa. Mphamvu yamaginito yamphamvu kwambiri imapezeka mkati mwa koyilo, ndipo mphamvu yamunda imakula ndi kuchuluka kwa ma coils ndi mphamvu yapano. Ma electromagnets amatha kusinthasintha ndipo amatha kusintha momwe maginito amayendera molingana ndi komwe akulowera, komanso amathanso kusintha mphamvu zomwe zikufunika kuti akwaniritse mphamvu ya maginito.
