Ngophuhliso olomeleleyo loshishino lwe-elektroniki, ukuchongwa kwendawo kwamanye amalungu olwakhiwo kutshintsha kancinane ukusuka kumlinganiso woqhagamshelwano wokuqala ukuya kumlinganiso ongaqhagamshelwangaInzwa yendawo yeholo kunye nemagnethi. Sinokukhetha njani umazibuthe ofanelekileyo ngokweemveliso zethu kunye nolwakhiwo? Apha senza uhlalutyo olulula.
Okokuqala, kufuneka siqonde izinto zemagnethi. Okwangoku, umazibuthe we-samarium cobalt kunye ne-neodymium iron boron zisetyenziswa ngokubanzi kwinzwa yendawo yeholo. Umahluko ophambili phakathi kweemagnethi ezimbini kukuba ngokusekelwe kumthamo ofanayo we-NdFeB umazibuthe womelele kunemagnethi ye-samarium cobalt; i-thermal excursion ye-samarium cobalt incinci kune-Nd-Fe-B; ukuchasana kwe-oxidation ye-samarium cobalt yomelele kune-Nd-Fe-B, kodwa ngokuqhelekileyo kukho isambatho esingaphandle kwemagnethi, enokusombulula ingxaki ye-oxidation; Umazibuthe we-samarium cobalt unokumelana nobushushu obungcono kune-NdFeB umazibuthe, kodwa ixabiso lokumelana nobushushu kuzo zombini izixhobo zemagnethi linokufikelela ngaphezulu kwe-200 ℃. Ke ngoko, xa ukhetha uhlobo lwemagnethi, kufuneka siyivavanye ngokudibanisa neendleko zokusebenza, ubushushu bokusebenza kunye nendawo yokusebenza. Ngokubanzi, i-NdFeB inokusetyenziswa ngakumbi, ngakumbi kuba ineempawu zemagneti ezibalaseleyo. Nangona kunjalo, xa usebenza kuluhlu olubanzi lobushushu, kuyacetyiswa ukuba ukhethe i-samarium cobalt magnet ngenxa ye-thermal drift yayo encinci.
Ukongeza, kufuneka simisele ezinye iiparameters ezisisiseko umazibuthe. Ngokolwazi lwendawo yovavanyo kunye nesalathiso esishukumayo sento, sifumanisa ukuba i-magnetization direction yemagneti i-diametrical okanye i-axial. Ukongeza, kumiselwa ukuba kukhethwe aumazibuthe osisikwereokanye aimagnethi yesilindangokwesakhiwo sofakelo. Ewe, ngamanye amaxesha kufuneka silungise imilo yemagnethi ngokwesakhiwo. Kukho enye into efunekayo malunga ne-magnet flux, ehlala iyinkxalabo yethu ekukhetheni imagnethi. Enyanisweni, kufuneka siyihlalutye kule miba mibini ilandelayo:
1. Amandla ombane owenziwe ngumbono wesikhundla seholo ngokwawo kunye noluhlu lwemagnethi oludityanisiweyo kwicala ngalinye luya kuphawulwa ngokucacileyo kwincwadi yedatha yenzwa.
2. Umgama phakathi kwemagnethi kunye nenzwa ngokwayo ngokuqhelekileyo inqunywe yimveliso yesakhiwo. Ngokwale miba mibini ingasentla kunye negophe lotshintsho lwemagnethi kumzobo ongezantsi njengomzekelo, sinokumisela amandla ombane wemagnethi efunekayo.
Okokugqibela, kufuneka siqonde ukuba oko akuthethi ukuba logama nje intsimi yamagnetic iwela kwiimfuno zoluhlu lwenzwa, umazibuthe unokuba kude kwinzwa. Nangona i-sensor ngokwayo inomsebenzi wokulinganisa, kufuneka siqonde ukuba xa i-magnet ikude kakhulu kwi-sensor, ukuhanjiswa kwentsimi yamagnetic ngokwayo kunzima ukuqinisekisa umgca okanye ukusondela kumgca. Oku kuthetha ukuba ngokutshintsha kwesikhundla kunye nokusabalalisa okungekho mgca kwintsimi yamagnetic ngokwayo, ukulinganisa kwenzwa kuya kuba nzima kwaye ukulinganisa kuya kuba nzima kakhulu, ukwenzela ukuba imveliso ayinayo i-reducibility.
Oku ngasentla luhlalutyo nje olulula lokhetho lwemagnethi kwizicelo zoluvo lweHolo. Siyathemba ukuba iya kuba luncedo kuwe. Ukuba uneminye imibuzo ngexesha lenkqubo yophuhliso, nceda uqhagamshelane nathi,Ningbo Horizon Magnetics. Sinokwenza unxibelelwano oluthe kratya kwaye sikunike inkxaso yobugcisa.
