Ndi chitukuko champhamvu cha makampani amagetsi, kuzindikiritsa malo a zigawo zina zamapangidwe kumasintha pang'onopang'ono kuchokera ku muyeso wapachiyambi kupita ku muyeso wosalumikizanaSensa ya malo a holo ndi maginito.Kodi tingasankhe bwanji maginito oyenera malinga ndi zomwe timagulitsa komanso kapangidwe kathu?Apa timapanga kusanthula kosavuta.
Choyamba, tiyenera kudziwa zinthu maginito.Pakali pano, samarium cobalt maginito ndi neodymium iron boron amagwiritsidwa ntchito kwambiri mu holo udindo sensa.Kusiyana kwakukulu pakati pa maginito awiri ndi kuti zochokera voliyumu yemweyo NdFeB maginito ndi wamphamvu kuposa samarium cobalt maginito;ulendo wotentha wa samarium cobalt ndi wocheperako kuposa wa Nd-Fe-B;kukana kwa okosijeni kwa samarium cobalt ndi kolimba kuposa kwa Nd-Fe-B, koma nthawi zambiri pamakhala zokutira kunja kwa maginito, zomwe zimatha kuthana ndi vuto la okosijeni;Samarium cobalt maginito ali bwino kutentha kukana kuposa NdFeB maginito, koma kutentha kukana kufunika kwa zipangizo zonse maginito angafikire oposa 200 ℃.Choncho, posankha mtundu wa maginito, tiyenera kuunikira pamodzi ndi mtengo ntchito, kutentha ntchito ndi malo ntchito.Nthawi zambiri, NdFeB itha kugwiritsidwa ntchito kwambiri, makamaka chifukwa ili ndi mawonekedwe abwino kwambiri a maginito.Komabe, pogwira ntchito yotentha kwambiri, tikulimbikitsidwa kusankha maginito a samarium cobalt chifukwa cha kutentha kwake kochepa.
Komanso, tiyenera kudziwa zina zofunika magawo maginito.Malinga ndi chidziwitso cha malo oyesera komanso komwe kumayenda kwa chinthucho, timazindikira ngati mayendedwe a maginito a maginito ndi diametrical kapena axial.Kuphatikiza apo, zimatsimikiziridwa ngati kusankha asquare maginitokapena acylinder maginitomalinga ndi dongosolo la kukhazikitsa.Inde, nthawi zina timafunika kusintha mawonekedwe a maginito molingana ndi kapangidwe kake.Palinso chinthu china chofunikira chokhudza maginito flux, chomwe chakhala nkhawa yathu nthawi zonse pakusankha maginito.M’malo mwake, tifunikira kuusanthula m’mbali ziŵiri zotsatirazi:
1. Mphamvu ya maginito yomwe imapangitsidwa ndi sensa ya malo a holo palokha komanso kuchuluka kwa maginito kumalo aliwonse kudzadziwika bwino mu bukhu la data la sensor.
2. Mtunda pakati pa maginito ndi sensa yokha nthawi zambiri umatsimikiziridwa ndi kapangidwe ka mankhwala.Malingana ndi mbali ziwiri zomwe zili pamwambazi ndi kusintha kwa maginito kusinthika mu chithunzi pansipa monga chitsanzo, tikhoza kudziwa mphamvu ya maginito ya maginito ofunikira.
Pomaliza, tiyenera kumvetsetsa kuti sizikutanthauza kuti malinga ngati mphamvu ya maginito ikugwera pazofunikira za sensor, maginito amatha kukhala kutali ndi sensor.Ngakhale kuti sensa yokhayo imakhala ndi ntchito yowonongeka, tiyenera kumvetsetsa kuti pamene maginito ali kutali kwambiri ndi sensa, kugawa kwa magnetic field palokha kumakhala kovuta kutsimikizira mzere kapena pafupi ndi mzere.Izi zikutanthauza kuti ndi kusintha kwa malo ndi kugawa kosawerengeka kwa maginito okha, kuyeza kwa sensor kudzakhala kovuta ndipo kuwerengetsa kudzakhala kovuta kwambiri, kotero kuti mankhwalawa alibe reducibility.
Zomwe zili pamwambazi ndi kusanthula kosavuta kwa maginito osankhidwa mu Hall sensor applications.Tikukhulupirira kuti zikhala zothandiza kwa inu.Ngati muli ndi mafunso ena panthawi yachitukuko, chonde titumizireni,Ningbo Horizon Magnetics.Titha kulumikizananso ndikukupatsani chithandizo chaukadaulo.
