Izi ndizopindulitsa makamaka popanga ma transfoma ang'onoang'ono komanso opepuka komanso ma inductors popanda kusokoneza magwiridwe antchito. Kuphatikiza apo, ma nanocrystalline cores amawonetsa kutayika kocheperako komanso kutayika kwa mkuwa, zomwe zimapangitsa kuti pakhale mphamvu zochulukirapo komanso kuchepetsa ndalama zogwirira ntchito pamapulogalamu apamwamba - pafupipafupi. Ma Ferrite cores, ngakhale akugwira ntchito, samafanana ndi kuchepa kwamphamvu komanso kutayika kwa eddy komwe kumawonedwa mu zida za nanocrystalline, makamaka ngati ma frequency akuwonjezeka.

● Kukhazikika kwa Matenthedwe

Ubwino umodzi wofunikira wa nanocrystalline cores ndikukhazikika kwawo kwamafuta. Miyendo iyi imakhalabe yogwira ntchito pa kutentha kosiyanasiyana, kuthetsa kufunikira kwa kutentha kwakukulu panthawi ya mapangidwe. Kukhazikika kumeneku kumatsimikizira kudalirika ndi moyo wautali m'malo ovuta, chikhalidwe chomwe sichimatchulidwa mu ma ferrite cores.

● Kukula Kwapakati ndi Kuziziritsa

Kuchita bwino kwambiri komanso kutha kwa ma nanocrystalline cores kumasulira kumagulu ang'onoang'ono komanso mapangidwe osinthika. Kuchepetsa kukula kwapakati kumathandizira kuzirala komwe kumafunikira, nthawi zambiri kumapangitsa kuti pakhale mawonekedwe otseguka omwe amathandizira kuzizira bwino kwa mpweya. Mosiyana ndi izi, ma ferrite cores nthawi zambiri amafunikira zida zoziziritsa kwambiri kuti athe kuthana ndi kutentha, makamaka pakugwiritsa ntchito mphamvu zambiri.

Kuchepetsa Kutaya

● Kuwonongeka Kwambiri

Nanocrystalline cores imachepetsa kutayika kwakukulu, gawo lofunikira pakukhathamiritsa magwiridwe antchito ndi magwiridwe antchito, makamaka mu zosinthira ndi kuchuluka - kugwiritsa ntchito pafupipafupi. Mapangidwe awo a bala la tepi amachepetsa kwambiri kuwonongeka kwa hysteresis ndi eddy, zomwe zimapereka mwayi wochulukirapo kuposa ma ferrite cores. Kuchepetsa kutayika kumeneku kumakulitsa magwiridwe antchito a dongosolo lonse ndipo kumathandizira kupulumutsa mphamvu kwanthawi yayitali.

● Eddy Zowonongeka Panopa

Pamaulendo okwera, kutayika kwa eddy panopa kumakhala chinthu chofunika kwambiri. Zida za Nanocrystalline zikuwonetsa kutayika kwa eddy komwe kumachepetsedwa chifukwa cha mawonekedwe ake abwino, kuwapangitsa kukhala oyenera kwambiri - kugwiritsa ntchito pafupipafupi poyerekeza ndi ma ferrite cores, omwe amatha kutayika izi.

Mapeto

Ngakhale ma cores onse a ferrite ndi ma nanocrystalline cores ali ndi zoyenerera zawo, ma nanocrystalline cores amapereka magwiridwe antchito apamwamba malinga ndi kuthekera, kuchita bwino, komanso kukhazikika kwamafuta. Kutha kupanga zing'onozing'ono, zogwira mtima kwambiri za maginito zimapangitsa ma nanocrystalline cores kukhala chisankho choyenera pakugwiritsa ntchito kwamakono kwamagetsi. Ngakhale kukwera mtengo koyambirira, phindu lanthawi yayitali monga kuchepa kwa mphamvu zamagetsi komanso kudalirika kowonjezereka kumapangitsa kuti ndalamazo zitheke, kuyika ma nanocrystalline cores ngati njira yabwino kwambiri yopangira maginito apamwamba kwambiri.
