Kodi maginito a NdFeB ndi ati?

Maginito a NdFeB, omwe amadziwikanso kuti neodymium maginito, ndi maginito osatha opangidwa kuchokera ku aloyi ya neodymium, chitsulo ndi boron.Maginitowa amadziwika chifukwa cha mphamvu zawo zamaginito, amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo zamagetsi, magalimoto ndi mphamvu zowonjezera.Pali mitundu yosiyanasiyana ya maginito a NdFeB, kuphatikizamaginito omangika a NdFeBndimaginito a sintered neodymium.

ndi maginito
Alnico maginito okhazikika

Sintered neodymium maginitondi maginito ambiri a NdFeB.Amapangidwa kudzera mu njira yotchedwa sintering, momwe zopangira zimasungunuka mu ng'anjo ndikuzizizira kuti zikhale zolimba.Maginito omwe amabwera amakhala ndi mphamvu zakumunda ndipo atha kugwiritsidwa ntchito pamapulogalamu omwe amafunikira maginito amphamvu, monga ma mota amagetsi, ma jenereta ndi olekanitsa maginito.

Maginito a NdFeB ogwirizana nawo, komano, amapangidwa ndi kusakaniza ufa wa NdFeB ndi binder ya polima ndiyeno kupondereza kusakaniza mu mawonekedwe omwe mukufuna.Njirayi imatha kupanga maginito okhala ndi mawonekedwe ovuta komanso kukula kwake, kuwapangitsa kukhala oyenera kugwiritsa ntchito zosiyanasiyana.Maginito ogwirizana ndi NdFeBamagwiritsidwa ntchito m'mafakitale omwe kusinthasintha kwapangidwe ndi kutsika mtengo ndikofunikira, monga masensa, ma actuators ndi maginito zigawo.

Maginito onse a sintered neodymium ndi maginito omangika a neodymium ali ndi zabwino ndi zoyipa zawo.Maginito a Sintered neodymium amadziwika chifukwa champhamvu zawo zamaginito komanso kukana demagnetization, kuwapangitsa kukhala oyenera kugwiritsa ntchito movutikira.Komabe, amakhalanso osasunthika komanso amatha kuwonongeka, zomwe zimafuna zokutira zapadera kuti ziwateteze kuzinthu zachilengedwe.

Zambiri zaife

Mwambo womangidwa NdFeB maginito Komano, ndi kusintha kwambiri kamangidwe ndipo akhoza kupangidwa mu mabuku mkulu pa mtengo wotsika.Amakhalanso ndi kukana bwino kwa dzimbiri ndipo atha kugwiritsidwa ntchito m'malo omwemaginito a sintered neodymiumsangakhale oyenera.Komabe, mphamvu zawo za maginito ndizochepa poyerekeza ndi maginito a sintered neodymium ndipo sangakhale oyenera kugwiritsa ntchito kwambiri.

Mwachidule, sintered NdFeB maginito ndi mwambo womangidwa NdFeB maginito ndi mitundu iwiri yosiyana ya maginito NdFeB, aliyense ndi makhalidwe awo apadera ndi ntchito.Maginito a Sintered neodymium amadziwika chifukwa champhamvu zawo zamaginito komanso kukana demagnetization, kuwapangitsa kukhala oyenera kugwiritsa ntchito movutikira, pomwemaginito omangika a NdFeBperekani kusinthasintha kwapangidwe komanso kuchita bwino.Kumvetsetsa kusiyana pakati pa mitundu iwiriyi ya maginito a NdFeB ndikofunikira posankha maginito oyenerera pa ntchito inayake.
