Neodymium Magnets yog dab tsi?

Neodymium Magnets: Cov Khoom me me, Kev cuam tshuam loj heev hauv ntiaj teb

Los ntawm kev xav engineering, kev hloov pauv los ntawm cov hlau nplaum hauv tub yees mus rau hom neodymium yog ib qho kev muaj peev xwm. Lawv cov qauv zoo ib yam - ib qho yooj yim disc lossis thaiv - ntseeg qhov kev ua tau zoo sib nqus sib nqus. Qhov kev tsis sib haum xeeb no ntawm lawv cov tsos mob me me thiab lawv lub zog ua haujlwm hnyav tseem ua rau muaj kev sib tw tseem ceeb hauv kev tsim thiab kev siv. Ntawm no ntawm Fullzen, peb tau pom cov khoom muaj zog no hloov pauv cov khoom lag luam thoob plaws ntau thaj chaw. Tsis ntev los no, ib qho kev nce qib tau ntes qhov tsom teeb: sneeg lub qhov neodymium hlau nplaum. Dab tsi ua rau qhov kev tsim kho tshiab no yog li ingenious yog nws deceptive simplicity. Nws yog hom kev daws teeb meem ncaj nraim uas zoo nkaus li pom tseeb.

Ntau tshaj li Cov Hlau nplaum muaj zog

Yog tias koj tab tom pom qhov ua kom zoo dua lub tub yees hlau nplaum, koj yuav ploj tag nrho. Cov hlau nplaum neodymium (feem ntau hu ua NdFeB lossis "neo" hlau nplaum) sawv cev rau kev dhia hauv kev siv tshuab hlau nplaum. Tsim los ntawm cov hlau tsis tshua muaj hauv ntiaj teb, lawv ua tiav qhov zoo li lub cev tsis tuaj yeem: tsim kom muaj zog sib nqus zoo kawg nkaus los ntawm cov pob khoom me me thiab lub teeb yuag. Qhov tshwj xeeb lub zog-rau-hnyav tus yam ntxwv tau dhau los ua lub cav tom qab cov khoom lag luam miniaturization hla suav tsis txheeb. Txawm hais tias peb tab tom tham txog kev cog lus kho mob uas cawm tib neeg txoj sia lossis lub suab nrov txo lub mloog pob ntseg uas koj tso siab rau thaum mus ncig, cov thev naus laus zis no tau hloov kho peb txoj kev ua tau zoo. Tshem tawm cov hlau nplaum neodymium, thiab niaj hnub no tech ib puag ncig yuav tsis paub.

Nkag siab txog Kev Siv Lub Zog

Peb tuaj yeem sib tham txog kev sib nqus txoj kev xav tsis kawg, tab sis qhov kev ua tau zoo hauv ntiaj teb hais ntau ntau. Siv peb cov N52 qib disc hlau nplaum ua piv txwv: nws hnyav ib yam li ib lub nyiaj tsis tau nqa tau tag nrho 2 kilograms. Qhov no tsis yog qhov kev xav hauv lab nkaus xwb-peb txheeb xyuas cov txiaj ntsig no los ntawm kev sim tsis tu ncua. Qhov kev muaj peev xwm no txhais tau hais tias cov kws tsim qauv tsim tuaj yeem hloov chaw siv cov hlau nplaum ceramic nrog cov kev xaiv neodymium uas siv chav tsawg dua.

Txawm li cas los xij, txhua tus neeg tsim qauv yuav tsum paub txog qhov tseem ceeb no: lub zog zoo li no yuav tsum tau ua tib zoo tuav. Kuv tus kheej tau pom cov hlau nplaum neodymium me me dhia hla workbenches thiab tawg thaum muaj kev cuam tshuam. Kuv twb pom lawv hle daim tawv nqaij hnyav txaus kom tawg. Cov hlau nplaum loj dua yuav tsum tau ceev faj ntau dua, nthuav tawm qhov txaus ntshai tiag tiag. Tsis muaj chaw rau kev sib tham ntawm no - kev tuav kom zoo tsis yog kev pom zoo xwb, nws yog qhov tsim nyog kiag li.

Txoj kev tsim khoom: Ob txoj hauv kev

Tag nrho cov hlau nplaum neodymium sib koom tib yam khoom xyaw: neodymium, hlau, thiab boron. Qhov txaus nyiam nyob hauv yuav ua li cas cov tuam txhab hloov cov khoom sib xyaw no rau hauv cov hlau nplaum ua haujlwm:

Sintered Neodymium Magnets
Thaum koj daim ntawv thov xav tau kev sib nqus sab saum toj, sintered hlau nplaum yog cov tshuaj. Kev tsim ua ntu zus pib nrog lub tshuab nqus tsev ntawm cov khoom siv raw, tom qab ntawd sib tsoo rau hauv cov hmoov zoo heev. Cov hmoov no tau compressed nyob rau hauv pwm nyob rau hauv ib tug muaj zog orienting magnetic teb, ces undergoes sintering. Yog tias koj tsis paub nrog lub sij hawm, xav txog sintering cov txheej txheem cua sov tswj uas khi cov khoom tsis tiav melting. Cov zis yog qhov ntom ntom, nruj dawb uas undergoes precises machiness machining machining machining (feem ntau npib tiv thaiv (feem ntau npib), thiab thaum kawg tau txais magnetized. Txoj kev no ua rau cov hlau nplaum muaj zog tshaj plaws muaj hnub no.

Bonded Neodymium Magnets
Qee zaum magnetic zog tsis yog koj qhov kev txhawj xeeb xwb. Qhov no yog qhov uas cov hlau nplaum sib txuas tuaj rau hauv. Cov txheej txheem koom nrog kev sib xyaw cov hmoov sib nqus nrog cov khoom siv polymer zoo li nylon lossis epoxy, uas yog tom qab ntawd zoo li siv compression lossis txhaj tshuaj molding. Cov txheej txheem no muab cov tuam txhab tsim khoom tsis muaj kev txwv tsim yooj yim. Kev sib haum xeeb? Qee qhov kev ua haujlwm sib nqus. Qhov zoo dua? Koj muaj peev xwm tsim intricate, precision duab uas yuav impractical los yog tsis yooj yim sua los tsim los ntawm sintering.

Threading Breakthrough

Cia kuv tam sim no qhia dab tsi tau dhau los ua ib qho ntawm peb qhov kev tsim kho tshiab tshaj plaws:neodymium hlau nplaum nrog cov ntsia hlau sib txuas. Lub tswv yim zoo li yuav luag yooj yim heev - txog thaum koj pom nws ua haujlwm hauv cov ntawv thov tiag tiag. Los ntawm kev sib txuas cov txheej txheem ntsia hlau ncaj qha rau hauv cov hlau nplaum nws tus kheej, peb tau daws qhov keeb kwm ntawm cov teeb meem feem ntau ntawm kev sib nqus sib nqus: txhim khu kev qha mounting.

Dheev, engineers tsis tawm tsam nrog cov nplaum nplaum los yog tsim kho cov khoom siv kho mob. Txoj kev daws teeb meem yuav zoo nkauj ncaj: tsuas yog ntsia hlau hlau ncaj qha mus rau hauv txoj hauj lwm. Qhov kev nce qib no tau ua pov thawj tshwj xeeb tshaj yog muaj txiaj ntsig rau:

Cov khoom siv nkag mus rau vaj huam sib luag yuav tsum tau kaw kom ruaj ntseg thaum lub sijhawm ua haujlwm thaum tso cai rau kev saib xyuas ceev

Txhim kho cov sensors thiab cov koob yees duab rau hauv cov qauv hlau lossis cov qauv tsheb

Prototyping kev npaj qhov twg cov khoom xav tau ob qho tib si kev nyab xeeb kev tso kawm thiab yooj yim reconfiguration

Nws yog ib qho ntawm cov kev daws teeb meem uas xav tias muaj tseeb tiag tiag-ib zaug koj tau pom nws cov txiaj ntsig.

Txhua qhov chaw nyob ib ncig ntawm peb

Qhov tseeb yog, koj nyob nraum yuav nyob ib puag ncig los ntawm neodymium hlau nplaum nyob rau lub sijhawm no. Lawv tau dhau los ua rau hauv cov thev naus laus zis niaj hnub no uas cov neeg feem coob tsis paub txog lawv qhov kev nthuav dav:
