Izixhobo zemagneti zinokuhlelwa zibe ngamacandelo amabini: imagnethi ye-isotropic kunye nemagnethi ye-anisotropic:
Iimagnethi ze-Isotropic zibonisa iimpawu ezifanayo zemagnethi kuwo onke amacala kwaye zinokwenziwa ngumagnet kulo naliphi na icala.
Iimagnethi ze-Anisotropic zibonisa iipropathi zemagneti ezahlukeneyo kumacala ahlukeneyo, kwaye zinendlela ekhethwayo yokusebenza kwemagnethi, eyaziwa ngokuba yi-orientation direction.
Iimagnethi eziqhelekileyo ze-anisotropic ziqukasintered NdFeBkwayesintered SmCo, ezizizixhobo zombini eziqinileyo.
Uqhelaniso yinkqubo ebalulekileyo ekuvelisweni kweemagnethi zeNdFeB
Umazibuthe wemagnethi uvela kulandelelwano lwemagnethi (apho imimandla yemagnethi ilungelelaniswa kwicala elithile).I-Sintered NdFeB yenziwa ngokucinezela umgubo wemagnethi ngaphakathi kokungunda.Inkqubo ibandakanya ukubeka i-powder magnetic kwi-mold, ukusebenzisa i-magnetic field eyomeleleyo usebenzisa i-electromagnet, kwaye kwangaxeshanye icinezela ngoxinzelelo ukuze ilungelelanise i-axis ye-magnetization elula yomgubo.Emva kokucinezela, imizimba eluhlaza ikhutshwa nguzibuthe, isuswe kubumba, kwaye izikhewu ezineziphumo ezinezalathiso zemagneti ezibekwe kakuhle ziyafunyanwa.Ezi zikhewu zisikwe ngokwemilinganiselo ekhankanyiweyo ukwenza iimveliso zentsimbi zemagneti zokugqibela ngokweemfuno zabathengi.
Ukuqhelaniswa nomgubo yinkqubo ebalulekileyo ekuveliseni iimagnethi ezisebenza ngokuphezulu ze-NdFeB.Umgangatho wokuqhelanisa ngexesha lesigaba sokuvelisa esingenanto siphenjelelwa yimiba eyahlukeneyo, kubandakanywa amandla entsimi yokuqhelanisa, ukumila kwesuntswana elingumgubo kunye nobukhulu, indlela yokwenza, ukuqhelaniswa kwentsimi yokuqhelanisa kunye nokwenza uxinzelelo, kunye nokuxinana okuxekethileyo komgubo ojoliswe kuyo.
I-Skew yamagnetic eyenziwe kwinqanaba le-post-processing inempembelelo ethile kwi-magnetic field distribution of the magnetic.
Imagnethi linyathelo lokugqibela lokunika umazibuthesintered NdFeB.
Emva kokusika izikhewu zemagneti ukuya kubukhulu obufunwayo, bangena kwiinkqubo ezinje nge-electroplating ukuthintela ukubola kwaye babe ngoomazibuthe bokugqibela.Nangona kunjalo, ngeli nqanaba, iimagnethi azibonakalisi umazibuthe wangaphandle kwaye zifuna imagneti ngokusebenzisa inkqubo eyaziwa ngokuba yi "charging magnetism."
Isixhobo esisetyenziselwa ukwenza imagneti sibizwa ngokuba yimagnetizer, okanye umatshini wemagnetizing.Imagnetiza kuqala ihlawulisa i-capacitor nge-voltage ephezulu ye-DC (oko kukuthi, igcina amandla), ize iyikhuphe ngekhoyili (i-magnetizing fixture) enokumelana okuphantsi kakhulu.Incopho yangoku ye-pulse yokukhupha ingaba phezulu kakhulu, ifikelele kumashumi amawaka e-amperes.Le pulse yangoku ivelisa indawo enemagnethi enamandla ngaphakathi kwemagnethi fixture, ethi ibambe ngokusisigxina umazibuthe obekwe ngaphakathi.
Iingozi zingenzeka ngexesha lenkqubo yemagneti, njengokugcwala okungaphelelanga, ukuqhekeka kweepali zemagnetizer, kunye nokuqhekeka kwemagnethi.
Ukuzaliswa okungaphelelanga kubangelwa ikakhulu kumbane wokutshaja onganelanga, apho intsimi yamagnetic eveliswa yi-coil ayifikeli kwi-1.5 ukuya ku-2 kumaxesha e-saturation magnetization yemagnethi.
Kwi-multipole magnetization, iimagnethi ezinezalathisi ezityebileyo zokujongwa zikwangumngeni ukugcwala ngokupheleleyo.Oku kungenxa yokuba umgama ophakathi kweepali eziphezulu nezisezantsi zemagnetizer mkhulu kakhulu, okukhokelela kumandla obanele wemagnethi ukusuka kwiipali ukwenza isekethe yemagnethi evaliweyo.Ngenxa yoko, inkqubo yemagneti inokukhokelela kwizibonda zemagneti ezingalungelelananga kunye namandla angonelanga entsimi.
Ukuqhekeka kweepali ze-magnetizer kuqala kubangelwa kukuseta amandla ombane aphezulu kakhulu, ukudlula umda okhuselekileyo wombane womatshini wemagneti.
Iimagnethi ezingasebenziyo okanye iimagnethi eziye zakhutshwa ngokwenxalenye yemagnethi kunzima kakhulu ukugcwala ngenxa yokuphazamiseka kwemimandla yazo yokuqala.Ukufezekisa i-saturation, ukuchasana nokufuduka kunye nokujikeleza kwezi ndawo kufuneka zoyiswe.Nangona kunjalo, kwiimeko apho umazibuthe ungagcwalanga ngokupheleleyo okanye unozibuthe oshiyekileyo, kukho imimandla yemagnethi ebuyela umva ngaphakathi kuyo.Nokuba imagnethi ibheka phambili okanye ngasemva, ezinye iindawo zifuna umva wemagnethi, nto leyo enyanzelisa ukoyiswa kwamandla angaphakathi okunyanzeliswa kule mimandla.Ke ngoko, intsimi yemagnethi eyomeleleyo kunokuba ifuneka ngokwethiyori iyimfuneko kwimagnetization.
