Nge
ngoku, i-NdFeB isetyenziswe ngokubanzi kwiinkalo ezahlukeneyo, njengeerobhothi,
iinjini zoshishino, izixhobo zasekhaya, ii-earphones, njl. Namhlanje siza
ukwazisa ukusetyenziswa kweemagnethi ezisisigxina ze-NdFeB kwizithuthi zamandla amatsha.
Izithuthi zamandla amatsha ikakhulu zibandakanya izithuthi ezixubileyo kunye nezithuthi zombane ezisulungekileyo.
Ukusebenza okuphezulu kwe-NdFeB izixhobo zemagnethi ezisisigxina zisetyenziswa ikakhulu ekuqhubeni
iimoto zeenqwelo zamandla amatsha. Qhuba iimoto ezifanelekileyo kwizithuthi zamandla amatsha
ikakhulu ibandakanya umazibuthe osisigxina iimotor synchronous, AC motors asynchronous kunye
Ukutshintsha imagnethi phakathi kwabo, imagnethi esisigxina ye-synchronous motor ine
ibe yeyona moto iphambili ngenxa yoluhlu olubanzi lwesantya, amandla aphezulu
ukuxinana, ubungakanani obuncinci, kunye nokusebenza okuphezulu. Iimagnethi ezisisigxina zeNdFeB zine
iimpawu zemveliso yamandla ombane aphezulu, amandla angaphakathi okunyanzeliswa aphezulu
kunye ne-remanence ephezulu, enokuphucula ngokufanelekileyo ubuninzi bamandla kunye ne-torque
Ubuninzi beenjini, kwaye zisetyenziswa ngokubanzi kwiirotor zemagnethi ezisisigxina.
EPS
(Electric Power Steering System) lelona candelo lisebenzisa eyona nto isisigxina
iimagnethi (0.25kg/isithuthi) ukongeza kwimoto yokuqhuba. Uncedo lwamandla
I-micromotor kwi-EPS yinjini yemagnethi esisigxina, eneemfuno eziphezulu ze
ukusebenza, ubunzima kunye nomthamo. Ke ngoko, izixhobo zemagnethi ezisisigxina kwi
Ii-EPS zezona zisebenza kakhulu kwi-sintered okanye iimagnethi ze-NdFeB ezicinezelwe ngokushushu.
Kwi
Ukongeza kwimoto yokuqhuba izithuthi zamandla amatsha, iimoto eziseleyo
imoto zonke micro-motor. Iinjini ezincinci zineemfuno eziphantsi kwimagnetism.
Okwangoku, i-ferrite yeyona nto iphambili. Nangona kunjalo, ukusebenza kakuhle kweenjini zokusetyenziswa
I-NdFeB inyuswe nge-8-50%. Ukusetyenziswa kwamandla kuncitshiswa nge-10% kunye ne
ubunzima buncitshiswe ngaphezu kwe-50%, eye yaba yindlela yokuphuhlisa
iinjini ezincinci kwixesha elizayo.
Kuba
Umzekelo, izinzwa ezahlukeneyo kwiimoto ziyindawo apho iimagnethi ezisisigxina ze-NdFeB zikhona
isetyenziswe kwizithuthi zamandla amatsha. Abenzi boluvo abasebenzisa iimagnethi ezisisigxina ubukhulu becala
zibandakanya: abenzi boluvo umgama, abenzi boluvo brake, abenzi boluvo ibhanti lesihlalo, etc. Bona ikakhulu
sebenzisa izinzwa zeHolo. Kwizinzwa zeHolo, iimagnethi ezisisigxina zisetyenziselwa ukuvelisa
umhlaba wemagnethi ukwenza izinto zeHolo zivelise imisinga ye-offset, ngaloo ndlela
ukuvelisa amandla e-electromotive, kunye ne-miniaturization kunye nokuhlanganiswa kwe
Uphuhliso lwenzwa yeholo, ukukhethwa kweemagnethi ezisisigxina zivame ukusebenzisa i-NdFeB
iimagnethi ezisisigxina ezineempawu ezintle zemagneti kunye nobukhulu obuncinci.
Imoto
izithethi zikwayenye indawo apho iimagnethi ezisisigxina zeNdFeB zifakwa kuyo
izithuthi zamandla amatsha. Ukusebenza kweemagnethi ezisisigxina kunempembelelo ngqo
kumgangatho wesandi sezithethi. Ukuphakama koxinano lwemagnethi eguquguqukayo
imagnethi esisigxina, iphezulu uvakalelo lwezithethi kwaye ngcono
eyedlulayo. Ngokubanzi, sisithethi Kulula ukwenza a
isandi, nesandi asiludaka. Iimagnethi ezisisigxina zezithethi kwi
imarike ikakhulu ziquka AlNiCo, ferrite kunye NdFeB. Iimpawu zemagnethi ze
I-NdFeB iphezulu kakhulu kunezo ze-AlNi kunye ne-ferrite. Ngokukodwa kwizinga eliphezulu
izithethi, uninzi lwazo zisebenzisa i-NdFeB.
Yethu
inkampani ibonelela ngeentlobo ngeentlobo ze-NdFeB, i-NdFeB edityanisiweyo, inaliti eyenziwe ngumagnethi
amakhonkco, iithayile ezinozibuthe ze-ferrite, iithayile zemagneti ezomeleleyo zeNdFeB, njl. Sibonelela
iinkonzo ezilungiselelwe abathengi, nceda uzive ukhululekile ukuqhagamshelana nathi ukuba ufuna.
