Ngwa nke NdFeB Igwe Ọdụdọ na-adịgide adịgide n'ime ụgbọ ala ike ọhụrụ

2022-12-29

Na ugbu a, a na-eji NdFeB eme ihe n'ọtụtụ ebe dị iche iche, dị ka robots, moto ụlọ ọrụ mmepụta ihe, ngwa ụlọ, ekwe ntị, wdg Taa, anyị ga-eme ewebata ngwa nke NdFeB magnetik na-adịgide adịgide n'ime ụgbọ ala ume ọhụrụ. Ụgbọ ala ume ọhụrụ na-agụnyekarị ụgbọ ala ngwakọ na ụgbọ ala eletrik dị ọcha. Ihe ndọta na-adịgide adịgide nke NdFeB dị elu ka a na-ejikarị na draịva moto nke ụgbọ ala ume ọhụrụ. Ụgbọala moto dabara adaba maka ụgbọ ala ume ọhụrụ tumadi gụnyere moto synchronous magnet na-adịgide adịgide, moto asynchronous AC na Ịmafe magnetik n'etiti ha, na-adịgide adịgide magnet synchronous moto nwere ghọọ moto nke bụ isi n'ihi oke ọsọ ya dị obosara, ike dị elu njupụta, obere nha, na arụmọrụ dị elu. NdFeB magnetik na-adịgide adịgide nwere njirimara ngwaahịa ike magnetik dị elu, ike mmanye dị elu na elu remanence, nke nwere ike n'ụzọ dị irè melite ike njupụta na torque njupụta nke moto, a na-ejikwa ya na rotors magnet na-adịgide adịgide.

 

EPS (Electric Power Steering System) bụ akụrụngwa na-eji ihe na-adịgide adịgide magnets (0.25kg / ụgbọ ala) na mgbakwunye na moto mbanye. Ike-enyere aka micromotor na EPS bụ moto magnet na-adịgide adịgide, nke nwere nnukwu ihe achọrọ maka ya arụmọrụ, ibu na olu. Ya mere, ihe ndọta na-adịgide adịgide na EPS bụ ihe ndọta NdFeB na-ekpo ọkụ na-arụ ọrụ nke ọma.

N'ime mgbakwunye na-akwọ ụgbọala moto nke ọhụrụ ume ugbo ala, ndị Motors na ndị ọzọ nke ụgbọ ala ahụ niile bụ obere moto. Micro-moto nwere obere chọrọ na magnetism. Ugbu a, ferrite bụ isi. Otú ọ dị, arụmọrụ nke moto na-eji NdFeB na-abawanye site na 8-50%. A na-ebelata oriri ike site na 10% na arọ na-ebelata ihe karịrị 50%, nke aghọwo mmepe na-emekarị nke micro Motors n'ọdịnihu.

 

Maka ihe atụ, dị iche iche sensọ na ụgbọ ala bụ a idaha ebe NdFeB na-adịgide adịgide magnet bụ etinyere na ụgbọ ala ume ọhụrụ. Sensọ na-eji magnet na-adịgide adịgide tumadi gụnyere: ihe mmetụta dị anya, sensọ breeki, sensọ belt oche, wdg. Ha tumadi jiri ihe mmetụta Ụlọ Nzukọ. Na sensọ Ụlọ Nzukọ, a na-eji magnet na-adịgide adịgide na-emepụta oghere magnetik iji mee ka ihe ndị dị n'Ụlọ Nzukọ na-emepụta mmiri mmiri na-akwụsị, si otú ahụ na-amụba ike electromotive, na miniaturization na mwekota nke Mmepe ihe mmetụta Ụlọ Nzukọ, nhọrọ nke magnets na-adịgide adịgide na-achọ iji NdFeB ihe ndọta na-adịgide adịgide nwere ezigbo magnetik na obere nha.

 

Ụgbọ ala ndị na-ekwu okwu bụkwa ọnọdụ ọzọ ebe a na-etinye ndọta na-adịgide adịgide NdFeB ụgbọ ala ume ọhụrụ. Ịrụ ọrụ nke magnet na-adịgide adịgide nwere mmetụta kpọmkwem na ụda olu nke ndị na-ekwu okwu. Nke dị elu njupụta ndọta nke magnetik na-adịgide adịgide, na-enwe mmetụta dị elu nke ndị na-ekwu okwu na mma nke na-agafe agafe. N'ikwu okwu n'ozuzu, ọ bụ ọkà okwu Ọ dị mfe ịme a ụda, ma ụda adịghị apịtị. Ihe ndọta na-adịgide adịgide nke ndị na-ekwu okwu na ahịa gụnyere AlNiCo, ferrite na NdFeB. Njirimara magnetik nke NdFeB dị nnọọ elu karịa nke AlNi na ferrite. Karịsịa maka elu-ọgwụgwụ ndị na-ekwu okwu, ọtụtụ n'ime ha na-eji NdFeB.

 

Anyị Ụlọ ọrụ na-enye ụdị NdFeB dị iche iche, NdFeB jikọtara ọnụ, magnetik injection mgbanaka, ferrite magnetik taịlị, NdFeB ike magnetik taịlị, wdg Anyị na-enye ahaziri ọrụ maka ndị ahịa , biko nweere onwe gị ịkpọtụrụ anyị ma ọ bụrụ na ịchọrọ.
