Kuyamba kwa isotropic ferrite ndi anisotropic ferrite

Kufotokozera Kwachidule:

Maginito olimba a ferrite ndi a maginito a sintered okhazikika, omwe pakadali pano ndi amodzi mwa maginito omwe amagwiritsidwa ntchito kwambiri, ndipo mtengo wake ndi wotsika kwambiri.Maginito a Ferrite amapangidwa makamaka ndi SrO ndi Fe2O3 monga zida zazikulu zopangira, ndipo amapangidwa ndi njira ya ceramic sintering.Kusiyanitsa ndi maginito ena okhazikika ndikuti ferrite si ya maginito osowa padziko lapansi.

Kuphatikiza apo, pali mitundu iwiri ya maginito a ferrite, isotropic ndi anisotropic.Maginito a Isotropic ferrite amatanthawuza kuti palibe coil yopangira maginito panthawi yomanga ndi kukanikiza, ndipo mayendedwe a magnetization amatsimikiziridwa.Ndiko kunena kuti, maginito akamaliza, amatha kukhala ndi maginito mbali zonse.The anisotropic ferrite maginito amatanthauza maginito anatsimikiza mu koyilo pa akamaumba ndi kukanikiza, ndiko kunena, ziribe kanthu momwe magnetize iwo, ndi magnetization malangizo palibe kusintha.

Simungathe kudziwa kuchokera pakuwoneka.The isotropic pamene kukanikiza (yowuma kukanikiza kapena chonyowa kukanikiza), pali maginito, kotero kuti mosavuta magnetization olamulira wa ufa maginito ndi zogwirizana.The anisotropic ndi pafupifupi katatu kuposa isotropic imodzi.The isotropic ndi yosavuta kuposa anisotropic popanga.Chifukwa chake, mtengo wa zida ndi mtengo wamagetsi a isotropic ndi wotsika mtengo, koma mphamvu ya maginito ndiyochepa kwambiri.

Ubwino wathu:
1. Kuchita kwamtengo wapamwamba: Tili ndi luso lamakono ndi zipangizo, katundu wapamwamba ndi mautumiki, ndi mitengo yabwino.Makamaka khalidwe wakhala anazindikira ndi makasitomala ndipo analandira modzitamandidwa makasitomala.
2. Kukhazikika kwakukulu: Tatengera luso lamakono ndi zipangizo, ndipo zogulitsa zimasonyeza kukhazikika kwakukulu pakugwiritsa ntchito, zomwe zingathe kukwaniritsa zofunikira za makasitomala kuti zikhale zokhazikika.
3. Wide ntchito: Zogulitsa zathu zitha kugwiritsidwa ntchito kwambiri pamagetsi ndi zamagetsi, kulumikizana, zamankhwala, magalimoto ndi magawo ena, ndikupatsa makasitomala mayankho athunthu, omwe amatha kusinthidwa malinga ndi zosowa za makasitomala, kuti apereke dongosolo labwino kwambiri. .
4. Zolondola kwambiri: Timatengera luso lapamwamba lopanga zinthu ndi zipangizo kuti titsimikizire kuti mankhwalawa ndi olondola kwambiri.
5. Kutumiza mofulumira: Tili ndi ndondomeko yokwanira yopangira zinthu ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.Mamembala amgululi ali ndi chidziwitso chambiri pamakampani ndipo amatha kupatsa makasitomala mayankho ndi ntchito zomwe akufuna.

Kugwiritsa ntchito

Ferrite maginito ndi imodzi mwa maginito omwe amagwiritsidwa ntchito kwambiri padziko lonse lapansi, amagwiritsidwa ntchito makamaka pamagetsi a PM motor ndi zokuzira mawu, komanso zina zosungidwa ngati maginito okhazikika, maginito otulutsa maginito, cholekanitsa maginito, zokuzira mawu, zida za microwave, ma sheet othandizira maginito. , kumva AIDS ndi zina zotero.
