Kukula kwa maginito okhazikika a maginito kumagwirizana kwambiri ndi chitukuko cha zipangizo zokhazikika za maginito.dziko langa ndi dziko loyamba padziko lapansi kuti lipeze maginito azinthu zamaginito okhazikika ndikuzigwiritsa ntchito.Zaka zoposa 2,000 zapitazo, dziko lathu linagwiritsa ntchito maginito a maginito okhazikika kuti apange kampasi, yomwe yathandiza kwambiri panyanja, asilikali ndi madera ena.Yakhala imodzi mwazinthu zinayi zazikulu zomwe zidapangidwa m'dziko langa.

Kusamala kwa maginito okhazikika a maginito

1. Maginito dera dongosolo ndi mawerengedwe kamangidwe

Pofuna kupereka masewera athunthu kuzinthu zamaginito zamitundu yosiyanasiyana ya maginito okhazikika, makamaka maginito abwino kwambiri a maginito osowa padziko lapansi, ndikupanga ma motor maginito otsika mtengo, kapangidwe kake ndi njira zowerengera zamagalimoto anthawi zonse kapena ma motors olimbikitsa magetsi sangagwiritsidwe ntchito mophweka., lingaliro latsopano lapangidwe liyenera kukhazikitsidwa, ndipo maginito ozungulira maginito ayenera kufufuzidwanso ndikuwongolera.Ndi chitukuko chofulumira chaukadaulo wamakompyuta ndiukadaulo wamapulogalamu, komanso kuwongolera mosalekeza kwa njira zamakono zamapangidwe monga ma electromagnetic field manambala kuwerengetsera, kukhathamiritsa kapangidwe kake ndi kayeseleledwe kayeseleledwe, kudzera khama limodzi la motor Academy ndi uinjiniya dera, wakhala ponseponse. amagwiritsidwa ntchito mu chiphunzitso cha mapangidwe, Kupita patsogolo kwabwino kwapangidwa mu njira zowerengera, ukadaulo wamapangidwe ndi ukadaulo wowongolera, ndi zina zambiri, ndi njira zowunikira ndi kafukufuku ndi kusanthula kothandizidwa ndi makompyuta ndi mapulogalamu opangira kuphatikiza mawerengero a maginito amagetsi ndi kusanthula kofanana kwa maginito. njira apangidwa, ndipo mosalekeza kusintha..

2. Kuwongolera nkhani

Maginito okhazikika amatha kukhalabe ndi mphamvu ya maginito popanda mphamvu zakunja, komanso zimapangitsa kuti zikhale zovuta kwambiri kusintha ndikuwongolera mphamvu yake ya maginito kuchokera kunja.N'zovuta kwa okhazikika maginito jenereta kusintha linanena bungwe voteji ndi mphamvu chinthu kuchokera kunja, ndi okhazikika maginito DC galimoto sangathenso kusintha liwiro lake ndi kusintha njira malemeredwe.Izi zimachepetsa kuchuluka kwa ma mota a maginito okhazikika.Komabe, ndikukula kwachangu kwa zida zamagetsi zamagetsi komanso matekinoloje owongolera monga ma MOSFET ndi ma IGBT, ma motors okhazikika okhazikika atha kugwiritsidwa ntchito popanda kuwongolera maginito komanso kuwongolera zida.Popanga, ndikofunikira kuphatikiza matekinoloje atatu atsopano a zida za maginito osowa padziko lapansi, zida zamagetsi zamagetsi ndi kuwongolera kwa microcomputer, kuti maginito okhazikika azitha kuyenda pansi pamikhalidwe yatsopano yogwirira ntchito.

3. Vuto la demagnetization yosasinthika

Ngati mapangidwe kapena kugwiritsa ntchito kuli kosayenera, injini yamagetsi yokhazikika idzakhala pansi pa zomwe zimachitika chifukwa cha kutentha kwanthawi yayitali (NdFeB maginito okhazikika) kapena otsika kwambiri (ferrite maginito okhazikika), kapena ngati pali kugwedezeka kwakukulu kwamakina Ndizotheka kuyambitsa demagnetization yosasinthika, kapena kutayika kwa maginito, zomwe zimachepetsa magwiridwe antchito a mota komanso kuyipangitsa kuti isagwiritsidwe ntchito.Chifukwa chake, ndikofunikira kufufuza ndikupanga njira ndi zida zowonera kukhazikika kwamafuta azinthu zamaginito okhazikika oyenera opanga magalimoto, ndikuwunika mphamvu zotsutsana ndi demagnetization zamitundu yosiyanasiyana yamapangidwe, kuti mutenge njira zofananira kuwonetsetsa kuti pakupanga. ndi kupanga.Okhazikika maginito motors samataya maginito awo.

4. Nkhani zamtengo

Ma Ferrite maginito okhazikika, makamaka maginito ang'onoang'ono okhazikika a DC, akhala akugwiritsidwa ntchito kwambiri chifukwa cha kapangidwe kake kosavuta ndi kachitidwe, kuchepetsa kulemera kwake, ndipo nthawi zambiri kutsika mtengo wokwanira kuposa ma motors othamangitsa magetsi.Popeza maginito osowa padziko lapansi akadali okwera mtengo pakali pano, mtengo wa maginito osowa padziko lapansi nthawi zambiri ndi wokwera kuposa wamagetsi othamangitsa magetsi, omwe amafunika kulipidwa chifukwa cha kuchuluka kwake komanso kupulumutsa mtengo wake.Nthawi zina, monga ma coil motors a disk drive, magwiridwe antchito a maginito a NdFeB amawongolera, kuchuluka kwake ndi misa zimachepetsedwa kwambiri, ndipo mtengo wake umachepetsedwa.Pamapangidwe, ndikofunikira kufananiza magwiridwe antchito ndi mtengo malinga ndi nthawi zomwe zimagwiritsidwa ntchito komanso zofunikira kuti musankhe chisankho, komanso kupanga njira zamapangidwe ndi kukhathamiritsa kwapangidwe kuti muchepetse mtengo.
