✧ Isishwankathelo
Iimagnethi ze-NIB ziza kumabakala ahlukeneyo, ahambelana namandla ommandla wabo wemagnethi, ukusuka kwi-N35 (eyona nto ibuthathaka kwaye incinci kakhulu) ukuya kwi-N52 (eyona inamandla, ibiza kakhulu kwaye i-brittle ngakumbi).Imagnethi ye-N52 imalunga ne-50% yomelele kunozibuthe we-N35 (52/35 = 1.49).E-US, kuyinto eqhelekileyo ukufumana iimagnethi zebakala labathengi kuluhlu lwe-N40 ukuya kwi-N42.Kwimveliso yevolumu, i-N35 isetyenziswa rhoqo ukuba ubungakanani kunye nobunzima abuyiyo ingqalelo enkulu njengoko kubiza kancinci.Ukuba ubungakanani kunye nobunzima zizinto ezibalulekileyo, amabakala aphezulu asetyenziswa ngokuqhelekileyo.Kukho iprimiyamu kwixabiso lemagnethi yodidi oluphezulu ngoko kuqhelekile ukubona imagnethi i-N48 kunye ne-N50 esetyenziswa kwimveliso xa ithelekiswa ne-N52.
✧ Ligqitywa Njani iBakala?
Imagnethi ye-Neodymium okanye eyaziwa ngokuba yi-NIB, i-NefeB okanye iimagnethi ezinkulu zezona zinamandla kunye nezona zisetyenziswa kakhulu kwiimagnethi zorhwebo ezikhoyo kwihlabathi liphela.Ngokwakhiwa kweekhemikhali ze-Nd2Fe14B, iimagnethi ze-neo zinesakhiwo sekristale ye-tetragonal kwaye ikakhulu zenziwe zizinto ze-neodymium, i-Iron kunye ne-Boron.Ukutyhubela iminyaka, umazibuthe we-neodymium utshintshe ngempumelelo zonke ezinye iintlobo zeemagnethi ezisisigxina zokusetyenziswa ngokubanzi kwiimotor, i-elektroniki kunye nezinye izixhobo zemihla ngemihla zobomi.Ngenxa yomahluko kwimfuno yemagnethi kunye nokutsala amandla omsebenzi ngamnye, iimagnethi ze-neodymium zifumaneka lula kumabakala ahlukeneyo.Iimagnethi ze-NIB zihlelwa ngokwezinto ezenziwe ngazo.Njengomgaqo osisiseko, ukuphakama kwamabanga, kuya kuba namandla umazibuthe.
I-nomenclature ye-neodymium isoloko iqala ngo-'N' elandelwa linani elineedijithi ezimbini phakathi koluhlu lwama-24 ukuya kuma-52. Unobumba 'N' kumabanga we-neo magnets umele i-neodymium ngelixa amanani alandelayo emele eyona mveliso yamandla aphezulu umazibuthe olinganiswa kwi-'Mega Gauss Oersteds (MGOe).I-Mgoe luphawu olusisiseko lwamandla ayo nayiphi na imagnethi ye-neo ethile kunye noluhlu lwemagnethi eveliswa yiyo nakwesiphi na isixhobo okanye isicelo.Nangona uluhlu lokuqala luqala ngo-N24 nangona kunjalo, amabanga asezantsi awasaveliswa.Ngokufanayo, ngelixa awona mandla aphezulu emveliso ye-NIB eqikelelwa ukuba afikelele ku-N64 kodwa amanqanaba aphezulu anamandla anje awakaphononongwa ngokwentengiso kwaye i-N52 lelona bakala liphezulu le-neo langoku elenziwe lifumaneke kubathengi.
Naziphi na iileta ezongezelelweyo ezilandela ibakala zibhekisa kumazinga obushushu bemagnethi, okanye ukungabikho kwayo.Umgangatho wobushushu obuqhelekileyo ngu-Nil-MH-SH-UH-EH.Aba nobumba bokugqibela bamele elona qondo liphezulu lobushushu bokusebenza komgubasi okt iqondo lobushushu leCurie elinokumelana nemagnethi ngaphambi kokuba iphulukane nemagnethi ngokusisigxina.Xa umazibuthe esebenza ngaphaya kobushushu beCurie, isiphumo siya kuba yilahleko yemveliso, ukunciphisa imveliso kwaye ekugqibeleni ukungasebenzi kakuhle kweemagnethi.
Nangona kunjalo, ubungakanani bomzimba kunye nokumila kwayo nayiphi na imagnethi ye-neodymium nayo idlala indima ebalulekileyo ekukwazini kwayo ukusebenza ngokufanelekileyo kumaqondo obushushu aphezulu ngokuthelekisa.Ngaphezu koko, enye into ekufuneka uyikhumbule kukuba amandla omgangatho olungileyo wemagnethi alingana nenani, ukuze i-N37 ibe buthathaka kuphela nge-9% kune-N46.Eyona ndlela ithembekileyo yokubala ibakala elichanekileyo lemagnethi ye-neo kukusebenzisa umatshini wokuvavanya igrafu ye-hysteresis.
I-AH Magnet ngumboneleli wemagnethi womhlaba onqabileyo okhethekileyo kuphando, ukuphuhlisa, ukuvelisa kunye nokuthumela ngaphandle kwe-sintered neodymium yentsimbi yemagnethi ye-boron ephezulu, amabakala angama-47 emagnethi ye-neodymium eqhelekileyo, ukusuka ku-N33 ukuya kwi-35AH, kunye nochungechunge lwe-GBD ukusuka kwi-48SH ukuya kuma-45AH ziyafumaneka.Ukuba unomdla kwiimveliso zethu, nceda uqhagamshelane nathi ngoku!
