Cov qauv siv hlau nplaum haujlwm ruaj nrees thiab yuav tsum tau, pls xav tiv tauj peb, peb yuav muab koj cov tshuaj zoo meej sai li sai tau.
Cov hlau nplaum yeej muaj Neodymium (NdFeB) sib raug zoo hlau nplaum. Sib raug zoo NdFeB hlau nplaum yog ib qhov tseem ceeb tshaj plaws sib nqus khoom, uas qhib lub ntiaj teb tshiab ntawm tsab ntawv teev npe possibilities. Resins Thermo-elastomer thiab thermo-yas yuav tau zoo nrog rau ntau yam sib nqus hmoov daim ntawv txhaj tshuaj puab, compression hab yooj ywm hlau nplaum.
Cov ntaub ntawv bonded no xws li anisotropic thiab tsev uas siv cov "binders" xws li epoxy resins los tuav lub hmoov nyob hauv qhov chaw, ntau dua li "sintering" lub alloy. Zog cov khoom ntawm qhov sib raug zoo neo hlau nplaum li ntawm 5 MGOe los 15.1 MGOe.
Sib raug zoo neo hmoov uas ua los ntawm ntxuav tej thaum lawv tseem hais tias yuav tsum sib nqus thiab lub cev cov yam ntxwv. Cov hmoov no yog cov hom khoom siv hauv qhov siv thiab ua cov kev sib raug zoo av rare haujlwm ruaj nrees hlau nplaum, uas nyeg, yog siv nyob rau hauv motors thiab sensors ntaub rau ntau cov rau tej khoom siv thiab tag muaj ciaj uas muag cov khoom. Neodymium hlau, yog ib lub ntsiab rare ntiaj teb, yog tus thawj raw khoom hauv neo hmoov. Nws yog alloyed uas muaj iron thiab boron, tej zaum muaj nyob nrog rau lwm tus hais rau me me txog (xws li cobalt). Cov alloy melted thiab ces mus solidified ntawm yaj spinning yuav tsim neo hmoov nrog rau tus yam ntxwv yam rau qhov siv thiab ua cov hlau nplaum neo sib raug zoo.
Ntau lawm
Chav nd-Fe-B sib raug zoo hmoov hluavtaws cob los polymer tsim muaj cov hlau nplaum bonded. Ib txoj kev tseem ceeb ntawm manufacturing cov hlau nplaum uas yog los ntawm txoj kev txhaj tshuaj molding. Cov alloy siv rau qhov txheej txheem ntau lawm Nd-Fe-B yog ua los ntawm ib txoj kev quenching ceev ceev. Qhov kub molten Nd-Fe-B alloy no yuam mus ib nozzle me me quav unto ib tug dej txias nruas uas yog rotating rau tus ceev heev rau daim ntawv nyias crystalline Nd-Fe-B alloy ribbons uas yog crushed yuav mus ua hmoov. Cov hmoov ntxiv nyuam rau kev kho mob kub lug txhim khu cov quab yuam coercive thiab ces tov nrog cov khoom cua cob. Sib tov sib xyaw resulting kneaded, pelletized thiab ces xa mus rau lub molding kev txhaj. Ib cov pwm uas yuav tsim tau tus luaj li yam cov hlau nplaum yog thawj nchuav tsim los ntawm ib cov hlau thiab cov pellets muaj tej yam ua kua rau hauv cov pwm thiab melted ntawm kev kub siab. Neeg kho tshuab hydraulic siab yog koj yuav tus dej sij xyuas kom meej tias cov kab noj hniav li ntawm cov pwm no lawm ua tus sau. Ib lwm magnetic teb (rau cov hlau nplaum anisotropic) yog tau ntaub ntawv los ntawm cov hlau nplaum thaum txhaj tshuaj molding txheej txheem. Nws mam li pub txias thiab tshem tawm nrog ejecting pins. Muaj ntaub ntawv ntau heev hauv cov hlau nplaum lawm trimmed thiab siv. Cov hlau nplaum lawm yog ntsuam xyuas thiab packed.
Kev siv
Sib raug zoo neo hmoov yog incorporated ua heev heev kawg lag luam daim ntaub ntawv uas siv hlau nplaum neo sib raug zoo. Cov khoom uas yog neeg motors thiab sensors siv kab kev los ntawm cov khoom, xws li lub computer thiab lub chaw ua hauj lwm siv (e.g., hard disk drives thiab optical disk drive motors thiab fax mus, tshuab luam ntawv thiab luam ntawv stepper motors) DVR electronics (piv txwv li, tej video recorders thiab mp3 suab paj nruag players), automotive thiab muaj ntawv (piv txwv li, motors vaj huam sib luag ntsuas, tog motors thiab hnab cua sensors) thiab tsev cua tshuab (xws li kiv cua qab nthab).
Hom
● khoom MQP uas yog isotropic sib nqus hmoov uas yog siv rau cov siv thiab ua cov hlau nplaum sib raug zoo. Tsis kawm tuab si lug teb yog tsim nyog thaum cov hlau nplaum manufacturing txheej txheem muab kev MQP kuas hlau nplaum.
● MQP hmoov zog khwv:
Br = 730 mT - 1000mT (7.30 kG-10.00 kG)
Max (BH) = 97kJ/m3-140kJ/m3 (12.2MGOe 17.6 MGOe)
Hci = 525kA/m-1350kA/m (6.5kOe - 17.0kOe)
● MQA no anisotropic sib nqus hmoov uas yog siv rau cov siv thiab ua cov hlau nplaum sib raug zoo. Ib daim teb kawm tuab si lug yog tsim nyog thaum cov hlau nplaum manufacturing txoj kev muab cov anisotropy uas yields dua sib nqus khoom.
● MQFP tshuab, muaj feem xyuam rau MQP qib, thiaj li tau txoj hmoov phem particle me me ntawm 160 rau 5 micrometers.
● MQU muaj lub siab kawm isotropic hmoov uas yuav siv zus tau tej cov MQ2-ntaus hlau nplaum, uas yog tuab nkaus isotropic hlau nplaum.
Txhaj
Hlau nplaum puab txhaj yog muaj siv ferrite, neodymium-hlau-boron, los sis niam uas muaj ntaub ntawv sib nqus after ib chav uas nws kim heev zog. Hom ntawv qhia Nylon 6 mus rau 12 xyoos, PPS, thiab Polyamide. Cov binders thiab alloys sib nqus muaj peev xwm sawv ntau hom ntaub ntawv muaj peevxwm from below-40 ° C rau saum 180 ° C. Txhaj tshuaj molding txheej txheem yog suited zoo heev los molding daim intricate heev thiab nyias qhov chaw walled. Seem lawm yuav muaj nqis heev yooj yim los yog txoj hauv kev ntsuas. Sib nqus cov ntaub ntawv tau muab tsab ntawv nrog thaum txhaj puab ncaj qha hauv lossis kev tivthaiv uas twb muaj lawm los ua tej daim los ua ke. Hlau nplaum puab txhaj dimensionally yoog vim pwm muaj kab noj hniav, uas yog precisely machined, uas yuav ua rau lawm cov khoom uas feem ntau tsis tas yuav muab xov haujlwm ntxiv lawm. Qhov no eliminates tom haujlwm thiab thiaj li tag nrho cov nqi.
Compression
Compression NdFeB hlau nplaum muaj siv ntau isotropic neodymium hlau boron khoom qib, thiab cov crushed thiab powdered samarium cobalt ntaub ntawv sib raug zoo. Ob peb ua ke ntaub qhab nee zooli tseem siv los tsim kev sib nqus cov yam ntxwv. Compression sib raug zoo muaj hlau nplaum muab ntau sib nqus zog dua txhaj puab cov hlau nplaum vim lawv sib nqus particle ceev dua, tiam sis yog xwm mus yooj geometries. Cov ntawv siv epoxy yog tshuaj tua tsis yeej muaj kuab thiab automotive haus dej kom ntau. Txo corrosion ntawm lub ntiaj teb rare sib nqus cov ntaub ntawv, lawv muaj ntxiv coated nrog epoxy tom qab shaping. Rau tej ntaub ntawv kub ntau from below-40 ° C rau saum 165 ° C. Compression bonding yog tsim nyog tshaj rau cov lus kuj geometries ntawm cov kev txwv ntawm kev compaction. Tus nqi tooling rau compression bonding yog comparatively tsawg tsawg, ua zoo xaiv dua txhaj molding uas tagnrho muaj heev me me. Txawm li ntawd los, nrog automation txaj muag, compression tsevneeg tau kuj tau txais rau lub ntim kub raug, muaj tagnrho mus tsheej lab ntawm daim ib xyoos twg.
