Lub cev muaj zog tseem tuaj yeem luam 3D? Kev nce qib tshiab hauv kev kawm ntawm lub cev muaj zog sib nqus cores Cov tub ntxhais sib nqus yog ib daim ntawv zoo li cov khoom sib nqus nrog siab sib nqus permeability.Lawv feem ntau siv rau kev taw qhia kev sib nqus hauv ntau lub tshuab hluav taws xob thiab tshuab, suav nrog electromagnets, transformers, motors, generators, inductors thiab lwm yam khoom sib nqus. Txog tam sim no, 3D luam ntawv ntawm cov hlau nplaum sib nqus tau yog ib qho kev sib tw vim qhov nyuaj ntawm kev tswj cov tub ntxhais efficiency.Tab sis tam sim no ib pab neeg tshawb fawb tau tuaj nrog cov txheej txheem laser-based additive manufacturing workflow uas lawv hais tias tuaj yeem tsim cov khoom lag luam uas muaj hlau nplaum zoo tshaj rau cov mos-magnetic composites. ©3D Science Valley Dawb Ntawv
3D luam ntawv cov ntaub ntawv electromagnetic
Ntxiv kev tsim cov hlau nrog cov khoom siv hluav taws xob electromagnetic yog qhov kev tshawb fawb tshiab.Qee pawg R&D lub cev muaj zog tab tom txhim kho thiab koom ua ke lawv tus kheej 3D cov khoom luam tawm thiab siv lawv rau hauv lub cev, thiab tsim kev ywj pheej yog ib qho ntawm cov yuam sij rau kev tsim kho tshiab. Piv txwv li, 3D luam ntawv ua haujlwm nyuaj nrog cov khoom sib nqus thiab hluav taws xob tuaj yeem ua rau txoj hauv kev rau kev cai embedded motors, actuators, circuits thiab gearboxes.Cov tshuab zoo li no tuaj yeem tsim hauv cov chaw tsim khoom digital nrog tsawg sib dhos thiab tom qab ua tiav, thiab lwm yam, vim tias ntau qhov chaw yog 3D luam tawm.Tab sis rau ntau yam, lub zeem muag ntawm 3D luam ntawv loj thiab nyuaj lub cev muaj zog tsis tau ua tiav.Feem ntau vim tias muaj qee qhov kev xav tau nyuaj ntawm cov cuab yeej sab nraud, xws li cov pa me me rau lub zog kom muaj zog, tsis txhob hais txog qhov teeb meem ntawm ntau yam khoom siv.Txog tam sim no, kev tshawb fawb tau tsom mus rau ntau qhov "hauv paus" cov khoom, xws li 3D-luam ntawv mos-magnetic rotors, tooj liab coils, thiab alumina heat conductors.Tau kawg, cov hlau nplaum mos kuj yog ib qho ntawm cov ntsiab lus tseem ceeb, tab sis qhov teeb meem tseem ceeb tshaj plaws los daws cov txheej txheem 3D luam ntawv yog yuav ua li cas txo cov tub ntxhais poob.

Saum toj no yog ib txheej ntawm 3D luam tawm qauv ntsuas uas qhia cov nyhuv ntawm lub zog laser thiab luam ntawv ceev ntawm cov qauv ntawm cov hlau nplaum.
Optimized 3D printing workflow
Txhawm rau ua kom pom qhov ua tau zoo ntawm 3D luam ntawv sib nqus cov tub ntxhais ua haujlwm, cov kws tshawb fawb tau txiav txim siab cov txheej txheem kev pom zoo rau daim ntawv thov, suav nrog lub zog laser, scan nrawm, qhov sib nrug deb, thiab txheej txheej tuab.Thiab cov txiaj ntsig ntawm annealing tsis tau kawm kom ua tiav qhov tsawg kawg nkaus DC poob, quasi-static, hysteresis poob thiab siab tshaj permeability.Qhov zoo tshaj plaws annealing kub tau txiav txim siab yog 1200 ° C, qhov siab tshaj qhov txheeb ze yog 99.86%, qhov qis tshaj qhov roughness yog 0.041mm, qhov qis tshaj plaws hysteresis poob yog 0.8W / kg, thiab qhov kawg yield zog yog 420MPa. ▲Cov nyhuv ntawm lub zog nkag rau ntawm qhov chaw roughness ntawm 3D luam tawm hlau nplaum
Thaum kawg, cov kws tshawb fawb tau lees paub tias laser-based hlau additive manufacturing yog ib txoj hauv kev ua tau rau 3D luam ntawv lub cev muaj zog hlau nplaum cov ntaub ntawv.Hauv kev tshawb fawb yav tom ntej, cov kws tshawb fawb npaj siab ua tus yam ntxwv ntawm cov qauv microstructure kom nkag siab txog cov qoob loo loj thiab cov qoob loo, thiab lawv cov txiaj ntsig ntawm permeability thiab lub zog.Cov kws tshawb fawb tseem yuav tshawb xyuas ntxiv txoj hauv kev txhawm rau txhim kho 3D luam ntawv core geometry los txhim kho kev ua haujlwm.
