Ma ke kahua o ka ʻenekinia uila a me ka hoʻokaʻawale mana, ʻo ke koho ʻana i nā mea koʻikoʻi no nā mea hoʻololi a me nā inductors he kuleana koʻikoʻi ia i ka hoʻoholo ʻana i ka pono a me ka hana o nā lako. ʻElua mau koho kaulana no nā mea koʻikoʻi he amorphous core a me nanocrystalline core, e hāʻawi ana i nā waiwai kū hoʻokahi a me nā pono. Ma kēia ʻatikala, e ʻeli mākou i nā ʻano o ka amorphous core a me ka nanocrystalline core, a e ʻimi i nā ʻokoʻa ma waena o nā mea ʻelua.
He aha ka ʻiʻo Amorphous?
An ʻōpū amorphousʻO ia kekahi ʻano mea kumu magnetic i hōʻailona ʻia e kona ʻano atomika non-crystalline. Hāʻawi kēia hoʻonohonoho atomika kū hoʻokahi i nā cores amorphous i ko lākou mau waiwai kūikawā, me ka pohō kumu haʻahaʻa, ka permeability kiʻekiʻe, a me nā waiwai magnetic maikaʻi loa. ʻO ka mea maʻamau i hoʻohana ʻia no nā cores amorphous he mea hao-i hana ʻia, i loaʻa pinepine nā mea e like me ka hao, boron, silicon, a me ka phosphorus.
ʻO ke ʻano non-crystalline o nā ʻiole amorphous e hopena i kahi hoʻonohonoho kaulele o nā ʻātoma, kahi e pale ai i ka hoʻokumu ʻia ʻana o nā kikowaena magnetic a hoʻemi i nā pohō o ke au eddy. ʻO kēia ka mea e hana ai i nā ʻiole amorphous i mea kūpono loa no nā noi kahi e pono ai ka pohō ikehu haʻahaʻa a me ka permeability magnetic kiʻekiʻe, e like me nā mea hoʻololi hoʻokaʻawale mana a me nā inductors alapine kiʻekiʻe.
Hana ʻia nā ʻiʻo amorphous me ka hoʻohana ʻana i ke kaʻina hana paʻa wikiwiki, kahi e hoʻopau ʻia ai ka metala hoʻoheheʻe ʻia ma kahi wikiwiki loa e pale aku i ka hoʻokumu ʻia ʻana o nā ʻano crystalline. ʻO kēia kaʻina hana ka hopena i kahi ʻano atomika i nele i ke kauoha lōʻihi, e hāʻawi ana i ka mea i kona mau waiwai kūikawā.
He aha ka Nanocrystalline Core?
Ma ka ʻaoʻao ʻē aʻe, ʻo ka nanocrystalline core kahi ʻano o ka mea magnetic core i loaʻa i nā hua crystalline nui nanometer i hoʻokomo ʻia i loko o kahi matrix amorphous. Hoʻohui kēia ʻano hana pālua i nā pono o nā mea crystalline a me nā mea amorphous, e hopena ana i nā waiwai magnetic maikaʻi loa a me ka saturation flux density kiʻekiʻe.
Nā ʻiwi nanocrystallineʻO ka maʻamau, hana ʻia ia mai ka hui pū ʻana o ka hao, nickel, a me ka cobalt, me nā hoʻohui liʻiliʻi o nā mea ʻē aʻe e like me ke keleawe a me ka molybdenum. Hāʻawi ka ʻano nanocrystalline i ka permeability magnetic kiʻekiʻe, ka coercivity haʻahaʻa, a me ke kūpaʻa thermal kiʻekiʻe, e kūpono ana no nā noi mana kiʻekiʻe a me nā mea hoʻololi alapine kiʻekiʻe.
ʻO ka ʻokoʻa ma waena o Amorphous Core a me Nanocrystalline Core
ʻO ka ʻokoʻa nui ma waena o nā ʻōpū amorphous a me nā ʻōpū nanocrystalline aia i ko lākou ʻano atomika a me nā waiwai magnetic i hopena. ʻOiai he ʻano crystalline ʻole loa nā ʻōpū amorphous, hōʻike nā ʻōpū nanocrystalline i kahi ʻano pālua i haku ʻia me nā hua crystalline nui nanometer i loko o kahi matrix amorphous.
Ma ke ʻano o nā waiwai magnetic,nā ʻōpū amorphousua ʻike ʻia no ko lākou pohō haʻahaʻa haʻahaʻa a me ka permeability kiʻekiʻe, e kūpono ana iā lākou no nā noi kahi e pono ai ka pono o ka ikehu. Ma ka ʻaoʻao ʻē aʻe, hāʻawi nā ʻāpana nanocrystalline i ka saturation flux density kiʻekiʻe a me ke kūpaʻa thermal kiʻekiʻe, e kūpono ana iā lākou no nā noi mana kiʻekiʻe a me ke alapine kiʻekiʻe.
ʻO kekahi ʻokoʻa koʻikoʻi ʻo ia ke kaʻina hana. Hana ʻia nā ʻiʻo amorphous ma o ka hoʻopaʻa wikiwiki ʻana, ʻo ia hoʻi ke kinai ʻana i ka metala i hoʻoheheʻe ʻia ma kahi wikiwiki e pale aku ai i ka hoʻokumu ʻia ʻana o ka crystalline. I ka hoʻohālikelike ʻana, hana pinepine ʻia nā ʻiʻo nanocrystalline ma o ka annealing a me ka crystallization i kāohi ʻia o nā lipine amorphous, e hopena ana i ka hoʻokumu ʻia ʻana o nā hua crystalline nui nanometer i loko o ka mea.
Nā Manaʻo Noi
I ke koho ʻana ma waena o nā ʻiole amorphous a me nā ʻiole nanocrystalline no kahi noi kikoʻī, pono e noʻonoʻo ʻia kekahi mau mea. No nā noi e hoʻokau mua i ka pohō ikehu haʻahaʻa a me ka pono kiʻekiʻe, e like me nā mea hoʻololi hoʻokaʻawale mana a me nā inductors alapine kiʻekiʻe, ʻo nā ʻiole amorphous ka koho makemake pinepine ʻia. ʻO ko lākou pohō ʻiole haʻahaʻa a me ka permeability kiʻekiʻe e kūpono iā lākou no kēia mau noi, e hāʻawi ana i ka mālama ʻana i ka ikehu holoʻokoʻa a me ka hoʻomaikaʻi ʻana i ka hana.
Ma ka ʻaoʻao ʻē aʻe, no nā noi e koi ana i ka saturation flux density kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, a me nā hiki ke lawelawe mana kiʻekiʻe, ʻoi aku ka kūpono o nā ʻiwi nanocrystalline. ʻO kēia mau waiwai e hana i nā ʻiwi nanocrystalline i mea kūpono no nā mea hoʻololi mana kiʻekiʻe, nā noi inverter, a me nā lako mana alapine kiʻekiʻe, kahi e koʻikoʻi ai ka hiki ke lawelawe i nā ʻiwi flux magnetic kiʻekiʻe a mālama i ke kūpaʻa ma lalo o nā kūlana hana like ʻole.
I ka hopena, hāʻawi nā ʻōpū amorphous a me nā ʻōpū nanocrystalline i nā pono kūikawā a ua hana ʻia no nā koi noi kikoʻī. ʻO ka hoʻomaopopo ʻana i nā ʻokoʻa o ko lākou ʻano atomika, nā waiwai magnetic, a me nā kaʻina hana hana he mea nui ia no ka hoʻoholo ʻana i nā hoʻoholo naʻauao i ke koho ʻana i nā mea koʻikoʻi no nā mea hoʻololi a me nā inductors. Ma ka hoʻohana ʻana i nā ʻano ʻokoʻa o kēlā me kēia mea, hiki i nā ʻenekinia a me nā mea hoʻolālā ke hoʻomaikaʻi i ka hana a me ka pono o kā lākou hoʻolaha mana a me nā ʻōnaehana hoʻololi, e hāʻawi hope ana i nā holomua i ka pono o ka ikehu a me nā ʻenehana mana hoʻomau.
