High-performance Stator Raws li Additive Manufacturing Technology

Kev ua haujlwm siab stator raws li kev tsim khoom siv tshuab ntxiv

Cov motors yog ib qho tseem ceeb thiab tseem ceeb hauv kev lag luam niaj hnub no, thiab kev ua haujlwm ntawm cov motors feem ntau nyob ntawm qhov zoo ntawm stator, uas feem ntau yog ua los ntawm cov ntaub ntawv silicon steel. Kev tsim khoom ntxiv yog ib qho kev tsim tawm tshiab uas tuaj yeem tsim cov txheej txheem nyuaj dua thaum ua kom luv luv ntawm cov khoom lag luam.Fe-3wt. feem pua ​​Si ferritic cov khoom muaj cov khoom sib nqus zoo heev thiab cov khoom siv kho tshuab, uas tuaj yeem txhim kho kev ua tau zoo ntawm lub cev muaj zog, thaum lub electrocathorate qis dua li cov ntaub ntawv silicon steel, thiab cov khoom siv hluav taws xob zoo dua. Yog li, kev siv cov cuab yeej tsim khoom siv ntxiv thiab Fe-3wt. feem pua ​​Si ferritic khoom los tsim lub cev muaj zog stator muaj qhov tseem ceeb thiab daim ntawv thov tus nqi.

Tsis ntev los no, TeiN. Lamichhane thiab lwm tus kws tshawb fawb los ntawm Oak Ridge National Laboratory hauv Tebchaws Meskas tau ua kev tshawb fawb txog kev tsim khoom siv ntxiv thiab Fe-3wt. feem pua ​​Si ferrite cov khoom siv los tsim lub cev muaj zog stator, uas tuaj yeem paub tsis tau tsuas yog kev tsim cov stator ntawm cov duab nyuaj, tab sis kuj muaj ntau dua yooj thiab customizability.

Nyob rau tib lub sijhawm, nws tuaj yeem txo qhov kev loj hlob ntawm cov khoom lag luam thiab txhim kho kev tsim khoom, thiab qhov kev tshawb fawb no tau txais kev txhawb nqa los ntawm US Department of Energy thiab yog qhov kev tshawb fawb zoo heev.

Lub stator yog luam tawm los ntawm kev xaiv laser melting technology, ces ua tiav rau hauv nyias txheej, thiab thaum kawg superimposed rau hauv ib tug stator core. Selective Laser Melting (SLM) tshuab tau siv los luam Fe-3wt. feem pua ​​Si ferritic cov ntaub ntawv. SLM thev naus laus zis yog kev tsim khoom siv thev naus laus zis ntxiv rau cov khoom siv hmoov qhuav, uas yog yaj thiab txheej txheej los ntawm txheej los ntawm laser beam los tsim cov qauv peb-seem xav tau.

Piv nrog rau cov txheej txheem tsim khoom ib txwm muaj, SLM thev naus laus zis muaj qhov yooj yim dua thiab kho tau, thiab tuaj yeem tsim cov qauv nyuaj dua: Fe-3wt. feem pua ​​Si ferrite cov khoom yog cov khoom siv nrog cov khoom sib nqus zoo heev thiab cov khoom siv kho tshuab, uas tuaj yeem txhim kho kev ua haujlwm ntawm lub cev muaj zog. Nyob rau tib lub sijhawm, electro-cathorate ntawm cov khoom siv qis dua li cov ntaub ntawv silicon steel, thiab cov khoom siv hluav taws xob zoo dua. Daim ntawv thov ntawm cov khoom siv no tuaj yeem ua rau muaj kev ua tau zoo dua thiab ua haujlwm zoo dua rau kev tsim khoom lag luam.

Daim duab 1: Thawj txheej ntawm cov duab luam tawm thaum SLM (sab laug): Xya Fe-3wt. feem pua ​​Si stator cov qauv ua tiav (txoj cai)

Daim duab 2 Lub cev muaj zog: (a) SLM luam tawm stator thiab lub tog raj kheej; (b) 1.4mm thickness stator ntawv: (c) sib dhos stator winding: (d) rotor nrog BAAM luam NdFeB-PPS hlau nplaum; (e) sib dhos rotor; (f) vaj tsev rotor; (g, h) ua tiav lub cev muaj zog.

Txoj kev tshawb no kuj tau sim cov khoom ntawm cov ntaub ntawv luam tawm thiab muab piv rau cov paib silicon steel los xij. Cov txiaj ntsig tau pom tias qhov sib nqus permeability ntawm stator yog ntau dua 20 feem pua ​​​​siab dua li cov ntawv silicon steel ib txwm muaj, thiab qhov sib nqus saturation induction siv kuj tseem ntau dua 10 feem pua ​​​​siab dua li cov ntawv silicon steel ib txwm. Nyob rau tib lub sij hawm, lub zog thiab hardness ntawm lub stator yog ntau dua li cov tsoos silicon steel los xij, thiab Shenyin tus nqi kuj qis dua li cov ntaub ntawv silicon steel, thiab cov khoom hluav taws xob zoo dua. Qhov kev nce qib hauv kev ua tau zoo tuaj yeem ua rau muaj kev ua haujlwm siab dua thiab kev ua haujlwm zoo dua hauv kev tsim khoom ntawm lub cev muaj zog.
