Ngo
okwamanje, i-NdFeB isetshenziswe kabanzi emikhakheni ehlukahlukene, njengamarobhothi,
izinjini zezimboni, izinto zikagesi zasendlini, ama-earphone, njll. Namuhla sizokwenza
yethula ukusetshenziswa kozibuthe be-NdFeB ezimotweni ezintsha zamandla.
Izimoto zamandla amasha ikakhulukazi zihlanganisa izimoto eziyingxube nezimoto ezisebenza ngogesi.
Izisetshenziswa zikazibuthe ezisebenza kakhulu ze-NdFeB zisetshenziswa kakhulu ekushayeleni
izinjini zezimoto ezintsha zamandla. Shayela izinjini ezifanele izimoto ezintsha zamandla
ikakhulukazi zihlanganisa unomphela uzibuthe motors synchronous, AC motors asynchronous kanye
ukushintsha magnetic phakathi kwabo, unomphela uzibuthe synchronous motor has
ibe yinjini evamile ngenxa yobubanzi bayo bejubane elibanzi, amandla aphezulu
ukuminyana, usayizi omncane, nokusebenza kahle okuphezulu. Ozibuthe be-NdFeB unomphela bane-
izici zomkhiqizo wamandla kazibuthe aphezulu, amandla aphezulu okuphoqelela angaphakathi
kanye ne-remanence ephezulu, engathuthukisa ngempumelelo ukuminyana kwamandla kanye ne-torque
ukuminyana kwamamotho, futhi asetshenziswa kabanzi kumarotha ozibuthe ozibuthe unomphela.
EPS
(Electric Power Steering System) yingxenye esebenzisa unomphela kakhulu
ozibuthe (0.25kg/imoto) ngaphezu kwenjini yokushayela. Abasizwa amandla
I-micromotor ku-EPS iyinjini yamagnetic unomphela, enezidingo eziphezulu ze
ukusebenza, isisindo kanye umthamo. Ngakho, unomphela uzibuthe materials in
Ama-EPS ikakhulukazi amamagnethi e-NdFeB asebenza kakhulu noma acindezelwe ngokushisa.
Ku
ngaphezu kwenjini yokushayela yezimoto zamandla amasha, izinjini ezisele
zonke izimoto ziyizinjini ezincane. Amamotho amancane anezidingo eziphansi kumagnetism.
Njengamanje, i-ferrite iyona eyinhloko. Nokho, ukusebenza kahle motors usebenzisa
I-NdFeB inyuke ngo-8-50%. Ukusetshenziswa kwamandla kuncishiswe ngo-10% futhi
isisindo sincishiswa ngaphezu kuka-50%, okuye kwaba umkhuba wokuthuthukisa
ama-micro motors esikhathini esizayo.
Ngoba
isibonelo, izinzwa ezihlukahlukene ezimotweni ziyisigameko lapho kukhona omazibuthe be-NdFeB
isetshenziswa ezimotweni ezintsha ezisebenza ngamandla. Izinzwa ezisebenzisa ozibuthe baphakade ikakhulukazi
zihlanganisa: izinzwa zebanga, izinzwa amabhuleki, izinzwa ibhande lesihlalo, njll Ikakhulukazi
sebenzisa izinzwa zeHholo. Kuzinzwa zeHholo, kusetshenziselwa izibuthe ezihlala njalo ukukhiqiza
izinkundla kazibuthe ukwenza izakhi Hall ukukhiqiza offset imisinga, ngalokho
ukukhiqiza amandla e-electromotive, nge-miniaturization kanye nokuhlanganiswa kwe
Ukuthuthukiswa kwezinzwa zehholo, ukukhethwa kwamagnetic unomphela kuvame ukusebenzisa i-NdFeB
ozibuthe unomphela abanezakhiwo ezinhle kazibuthe nosayizi omncane.
Imoto
Izikhulumi nazo zingesinye isigcawu lapho kufakwa khona omazibuthe be-NdFeB
izimoto ezintsha zamandla. Ukusebenza kozibuthe unomphela kunomthelela oqondile
kwikhwalithi yomsindo wezipikha. Ukuphakama kwe-magnetic flux density
ozibuthe unomphela, ayanda ukuzwela kwezikhulumi futhi ngcono
okwedlulayo. Ngokuvamile, yisikhulumi Kulula ukwenza a
umsindo, futhi umsindo awukho udaka. Ozibuthe abangapheli bezikhulumi ku-
imakethe ikakhulukazi ihlanganisa i-AlNiCo, i-ferrite ne-NdFeB. Amandla kazibuthe we
I-NdFeB iphakeme kakhulu kunaleyo ye-AlNi ne-ferrite. Ikakhulukazi okusezingeni eliphezulu
izikhulumi, iningi lazo zisebenzisa i-NdFeB.
Eyethu
inkampani ihlinzeka ngezinhlobonhlobo ze-NdFeB, i-NdFeB eboshiwe, umjovo obunjiwe kazibuthe
izindandatho, amathayili kazibuthe ferrite, NdFeB amathayela kazibuthe aqinile, njll Sinikeza
amasevisi ngokwezifiso kumakhasimende, sicela ukhululeke ukuxhumana nathi uma udinga.
