✧ Isishwankathelo
Iimagnethi ze-NIB ziza kwiindidi ezahlukeneyo, ezihambelana namandla eemagnethi zazo, ukusuka kwi-N35 (eyona ibuthathaka kwaye ingabizi kakhulu) ukuya kwi-N52 (eyona inamandla, ibiza kakhulu kwaye ibuthathaka ngakumbi). Imagnethi ye-N52 inamandla malunga ne-50% kunemagnethi ye-N35 (52/35 = 1.49). E-US, kuyinto eqhelekileyo ukufumana iimagnethi zezinga labathengi kuluhlu lwe-N40 ukuya kwi-N42. Kwimveliso yomthamo, i-N35 idla ngokusetyenziswa ukuba ubungakanani kunye nobunzima aziyonto ibalulekileyo njengoko ingabizi kakhulu. Ukuba ubungakanani kunye nobunzima zizinto ezibalulekileyo, kusetyenziswa iindidi eziphezulu. Kukho ixabiso leemagnethi zezinga eliphezulu ngoko ke kuqhelekile ukubona iimagnethi ze-N48 kunye ne-N50 zisetyenziswa kwimveliso ngokuchasene ne-N52.
✧ Ibanga limiselwa njani?
Iimagnethi zeNeodymium okanye ezaziwa kakhulu njengeNIB, NefeB okanye iimagnethi ezinkulu zezona zimagnethi zinamandla kunye nezisetyenziswa kakhulu kwihlabathi liphela. Ngokwakhiwa kweekhemikhali zeNd2Fe14B, iimagnethi zeNeo zinesakhiwo sekristale ye-tetragonal kwaye zenziwe ikakhulu ngezinto zeNeodymium, iIron kunye neBoron. Kwiminyaka edlulileyo, imagnethi yeNeodymium itshintshe ngempumelelo zonke ezinye iintlobo zeemagnethi ezisisigxina ukuze zisetyenziswe ngokubanzi kwiimoto, kwii-elektroniki nakwezinye izixhobo ezahlukeneyo zobomi bemihla ngemihla. Ngenxa yokwahluka kwimfuno yemagnetism kunye namandla okutsala kumsebenzi ngamnye, iimagnethi zeNeodymium zifumaneka ngokulula kwiigreyidi ezahlukeneyo. Iimagnethi zeNIB zihlelwa ngokwezinto ezenziwe ngazo. Njengomthetho osisiseko, xa amanqanaba ephezulu, imagnethi iya kuba namandla ngakumbi.
Igama le-neodymium lihlala liqala ngo-'N' lilandelwe linani elinamanani amabini ngaphakathi koluhlu oluvela kuma-24 ukuya kuma-52. Unobumba u-'N' kwiimakethi ze-neo magnets umele i-neodymium ngelixa la manani alandelayo emele imveliso yamandla aphezulu yemagnethi ethile elinganiswa kwi-'Mega Gauss Oersteds (MGOe). I-Mgoe sisalathisi esisisiseko samandla ayo nayiphi na imagnethi ethile ye-neo kunye noluhlu lwentsimi yamagnetic eyenziwe yiyo kuyo nayiphi na isixhobo okanye usetyenziso. Nangona uluhlu lokuqala luqala nge-N24 nangona kunjalo, iimakethi ezisezantsi azisaveliswa. Ngokufanayo, ngelixa amandla aphezulu emveliso e-NIB aqikelelwa ukuba afikelela kwi-N64 kodwa amanqanaba aphezulu amandla anjalo akakahlolwa kurhwebo kwaye i-N52 yeyona nqanaba liphezulu le-neo langoku elifumaneka lula kubathengi.
Naziphi na ezinye iileta ezilandela inqanaba zibhekisa kumazinga obushushu emagnethi, okanye mhlawumbi ukungabikho kwayo. Amanqanaba obushushu aqhelekileyo yiNil-MH-SH-UH-EH. La magama okugqibela amele ubushushu obuphezulu bokusebenza, oko kukuthi ubushushu beCurie obunokumelwana nemagnethi ngaphambi kokuba ilahlekelwe yimagnethi yayo ngokusisigxina. Xa imagnethi isebenza ngaphaya kobushushu beCurie, isiphumo siya kuba kukulahlekelwa yimveliso, ukuncipha kwemveliso kunye nokupheliswa kwemagnethi okungenakulungiseka ekugqibeleni.
Nangona kunjalo, ubungakanani kunye nemilo yayo nayiphi na imagnethi ye-neodymium ikwadlala indima ebalulekileyo kubuchule bayo bokusebenza ngokufanelekileyo kumaqondo obushushu aphezulu. Ngaphezu koko, enye into ekufuneka uyikhumbule kukuba amandla emagnethi esemgangathweni alingana nenani, ngoko ke i-N37 ibuthathaka nge-9% kuphela kune-N46. Eyona ndlela inokuthenjwa yokubala inqanaba elichanekileyo lemagnethi ye-neo kukusebenzisa umatshini wokuvavanya igrafu ye-hysteresis.
I-AH Magnet ngumthengisi weemagnethi ezingaqhelekanga ogxile kuphando, uphuhliso, ukuvelisa nokuthumela ngaphandle iimagnethi ze-sintered neodymium iron boron ezisebenza kakuhle, ii-grades ezingama-47 zeemagnethi ze-neodymium ezisemgangathweni, ukusuka kwi-N33 ukuya kwi-35AH, kunye ne-GBD Series ukusuka kwi-48SH ukuya kwi-45AH ziyafumaneka.
