Ukusetyenziswa kweemagnethi eziSigxina zeNdFeB kwiZithuthi zaMandla amatsha

2022-12-29

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.
