ʻO ka hoʻonohonoho ʻana a me ka hoʻokalakupua ʻana o nā mākēneki NdFeB Sintered

ʻO ka skew magnetic i hana ʻia ma ka pae hoʻoponopono hope loa i kekahi hopena i ka hāʻawi ʻana i ke kahua magnetic o nā magnet.

ʻO ka magnetization ka hana hope loa e hāʻawi i ka magnetism ihoʻopaʻa ʻia ʻo NdFeB.

Ma hope o ka ʻoki ʻana i nā blanks magnetic i nā ana i makemake ʻia, hana lākou i nā kaʻina hana e like me ka electroplating e pale ai i ka corrosion a lilo i mau magnet hope loa.Eia nō naʻe, i kēia manawa, ʻaʻole hōʻike nā mea magnet i ka magnetism waho a koi aku i ka magnetization ma o kahi kaʻina i kapa ʻia ʻo "charging magnetism."

ʻO nā mea hana i hoʻohana ʻia no ka magnetizing ua kapa ʻia he magnetizer, a i ʻole ka mīkini hoʻokalakupua.Hoʻopi mua ka magnetizer i kahi capacitor me ka uila DC kiʻekiʻe (ʻo ia hoʻi, mālama i ka ikehu), a laila hoʻokuʻu iā ia ma o ka coil (magnetizing fixture) me ka haʻahaʻa haʻahaʻa.Hiki ke kiʻekiʻe loa ke kiʻekiʻe o ka manawa o ka pulse hoʻokuʻu, hiki i nā ʻumi kaukani amperes.Hoʻopuka kēia pulse o kēia manawa i kahi mākēneki ikaika i loko o ka mea hoʻoheheʻe magnetizing, kahi e hoʻopaneʻe mau ai i ka magnet i hoʻokomo ʻia i loko.

Hiki ke loaʻa nā pōʻino i ka wā o ke kaʻina hana magnetization, e like me ka saturation piha ʻole, ka haki ʻana o nā pou o ka magnetizer, a me ka haki ʻana o nā mea magnet.

ʻO ka saturation piha ʻole ma muli o ka lawa ʻole o ka hoʻouka ʻana i ka volta, kahi i hiki ʻole ai ke kahua magnetic i hana ʻia e ka coil i 1.5 a 2 mau manawa i ka saturation magnetization o ka magnet.

No ka multipole magnetization, paʻakikī hoʻi nā magnet me nā kuhikuhi kuhikuhi ʻoi aku ka paʻakikī e hoʻopiha piha.ʻO kēia ke kumu no ka nui loa o ka mamao ma waena o nā pou luna a me lalo o ka mea magnetizer, no laila ʻaʻole lawa ka ikaika o ke kahua magnetic mai nā pou e hana i kahi kaapuni magnetic paʻa pono.ʻO ka hopena, hiki i ke kaʻina hana magnetization ke alakaʻi i nā pou magnetic disorderly a me ka lawa ʻole o ka ikaika kahua.

ʻO ka haki ʻana o nā pou o ka magnetizer ma muli o ka hoʻonohonoho ʻana i ka uila kiʻekiʻe loa, ʻoi aku ma mua o ka palena uila palekana o ka mīkini magnetizing.

ʻOi aku ka paʻakikī o ka hoʻoheheʻe ʻia ʻana o nā magnet unsaturated a i ʻole nā ​​​​magnetized i hoʻokaʻawale ʻia ma muli o kā lākou mau kikowaena magnetic disordered mua.No ka hoʻokō ʻana i ka saturation, pono e hoʻokō ʻia ke kūʻē ʻana mai ka neʻe ʻana a me ka hoʻololi ʻana o kēia mau kikowaena.Eia nō naʻe, i nā hihia inā ʻaʻole piha piha ka magnet a i ʻole ke koena o ka magnetization, aia nā ʻāpana o ka pā magnetic i loko.ʻO ka magnetizing i ka mua a i ʻole ka hoʻohuli ʻana i ka ʻaoʻao, pono kekahi mau wahi i ka hoʻohuli ʻana i ka magnetization, pono i ka lanakila ʻana o ka ikaika coercive intrinsic i kēia mau wahi.No laila, ʻoi aku ka ikaika o ka māla ma mua o ka manaʻo e pono ai no ka magnetization.
