xaiv cov tub ntxhais hlau rau lub zog tshiab
May 21, 2026
Cov tub ntxhais hlau yog lub hauv paus ntawm cov hlau nplaum hluav taws xob ntawm cov tshuab hluav taws xob tshiab, thiab nws cov khoom xaiv ncaj qha cuam tshuam rau lub cev muaj zog lub zog ceev, kev siv hluav taws xob, kev ntseeg siab thiab tus nqi. Nrog rau txoj kev loj hlob ntawm lub zog tshiab ntawm lub zog ntawm kev kub ceev, kev ua haujlwm siab thiab lub teeb, kev xaiv cov khoom siv hlau tseem ceeb tau dhau los ua qhov tseem ceeb.
Core Indicators rau xaiv Tshiab Zog Tsav Hlau Cov Khoom Siv Hluav Taws Xob
Txhawm rau xaiv cov khoom siv hlau kom tsim nyog, nws yog ib qho tsim nyog yuav tsum tau tsom mus rau 5 cov cim tseem ceeb kom tsis txhob xaiv qhov muag tsis pom:
● Cov khoom sib nqus: Saturation magnetic flux ceev (Bs Ntau dua lossis sib npaug rau 1.4T rau lub zog tshiab), hlau poob (P1.0/400 Tsawg dua lossis sib npaug rau 15W / kg rau siab -cov motors ua tau zoo) thiab sib nqus permeability yog cov tub ntxhais, uas txiav txim siab lub zog ntawm lub cev muaj zog.
●Mechanical zog: Yield zog (σs Ntau tshaj los yog sib npaug rau 500MPa rau siab-ceev rotors), stacking yam (Ntau tshaj los yog sib npaug rau 97% rau siab-precision motors) thiab punchability xyuas kom lub cev muaj zog stability nyob rau hauv siab - khiav ceev.
● Hluav taws xob thiab thermal zog: Kev tiv thaiv siab dua tiv thaiv qhov poob tam sim no, thiab Curie kub siab dua lossis sib npaug li 200℃kom hloov mus rau qhov chaw ua haujlwm ntawm lub zog tshiab.
● Dimensional precision: Lub thickness kam rau ua ntawm ultra- cov ntaub ntawv nyias yog tsawg dua los yog sib npaug rau ± 0.01mm, thiab qhov saum npoo tsis muaj khawb los xyuas kom cov rwb thaiv tsev thiab stacking nyhuv.
● Tus nqi thiab cov txheej txheem hloov pauv: Kev ua haujlwm sib luag thiab tus nqi, thiab zam cov nqi ua haujlwm siab vim los ntawm cov khoom siv (xws li nkig amorphous alloys).
Mainstream Iron Core Materials for New Energy Motors
Tam sim no, cov ntaub ntawv tseem ceeb rau lub zog tshiab lub cev muaj zog hlau cores tsis yog - taw qhia silicon steel, amorphous alloys thiab nanocrystalline alloys, txhua tus muaj nws tus yam ntxwv thiab cov xwm txheej:
1) Tsis yog -Kev Taw Qhia Silicon Steel (Tus nqi tseem ceeb-Kev xaiv zoo)
Kev suav nyiaj ntau dua 90% ntawm kev ua lag luam, nws yog cov khoom siv hlau loj tshaj plaws rau lub zog tshiab. Nws muaj qhov sib npaug sib nqus thiab cov khoom siv kho tshuab, cov txheej txheem stamping thiab stacking, thiab tus nqi nruab nrab. 0.20/0.25mm ultra-nyias siab- qib zog (xws li B27AHV1500) yog thawj qhov kev xaiv rau siab -kev ua tau zoo motors, thaum qib 0.30/0.35mm yog haum rau tus nqi- cov qauv rhiab heev. Nws yog dav siv nyob rau hauv huab hwm coj- tsim cov tsheb neeg nrog caij, tsheb ua lag luam thiab lub zog tshiab tshiab.
2) Amorphous Alloy (Ultra-Low Loss Premium Choice)
Tsim los ntawm ultra- txias txias, nws muaj qhov tsis tshua muaj hlau tsis tshua muaj (1/5-1/10 ntawm cov pa silicon steel) thiab siab tiv taus, uas tuaj yeem txhim kho lub cev muaj zog ntau dua 98.5% thiab nce tsheb ntau. Qhov tsis zoo yog tias nws yog ib qho nyuaj thiab nkig, nrog cov khoom siv siab thiab cov nqi ua haujlwm, tsim rau siab -cov neeg caij tsheb kawg, cov khoom kim heev EVs thiab cov tshuab ua haujlwm siab.
3) Nanocrystalline Alloy (Tom ntej High-Frequency Low-Kev xaiv poob)
Annealed los ntawm amorphous alloy, nws muaj ultra-siab resistivity thiab tsis tshua muaj hlau poob ntawm high zaus (1-10kHz), nrog kub stability. Qhov tsis zoo yog qhov tsis tshua muaj qhov sib nqus sib nqus flux ntom ntom (≈1.2T) thiab tus nqi siab, haum rau siab -frequency auxiliary motors, ntawm -board chargers (OBC) thiab me me high-speed motors.
Scenario-Raws li kev xaiv ntawm cov khoom siv hlau
●High-kawg neeg nrog caij tsheb tsav motors (peak efficiency Ntau dua los yog sib npaug rau 97%, 15000-20000rpm): 0.20/0.25mm siab-lub zog qis-tsis yog- taw qhia silicon steel; Cov qauv zoo tshaj plaws tuaj yeem siv amorphous alloy stators + high-strength silicon steel rotors.
● Kev lag luam tsheb / logistics tsheb lub cev muaj zog: 0.30 / 0.35mm nruab nrab- qib siab tsis yog-silicon steel, ntsuas tus nqi thiab kev ntseeg tau.
●High-ceev auxiliary motors (Ntau dua lossis sib npaug li 20000rpm): 0.20mm ultra-nyias siab-silicon steel lossis nanocrystalline alloy.
● Tsawg- lub zog me me: 0.35 / 0.50mm cov pa uas tsis yog- taw qhia silicon steel, tsom rau kev tswj tus nqi.
Cov lus qhia tseem ceeb rau tus nqi thiab kev tswj xyuas
① Thickness optimization: 0.25mm yog qhov kev pom zoo ntawm kev poob, lub zog thiab tus nqi;
② Rwb thaiv tsev txheej: xaiv cov txheej txheem organic rau cov qauv ua qauv thiab cov txheej txheem inorganic sib xyaw rau siab - qauv nrawm;
③ Cov ntaub ntawv muab qhab nia: siv qib siab - cov ntaub ntawv qib siab rau stators thiab nruab nrab - cov ntaub ntawv qib rau rotors los txo cov nqi.

Kev xaiv ntawm lub zog tshiab lub cev muaj zog hlau cov ntaub ntawv tseem ceeb yuav tsum ua raws li lub hauv paus ntsiab lus ntawm "scenario matching, indicator balance and cost-performance optimization". Tsis yog-qhia silicon steel yog thawj qhov kev xaiv rau ntau lawm, thaum amorphous thiab nanocrystalline alloys haum rau siab - kawg thiab siab - ceev xwm txheej. Hauv kev xaiv tiag tiag, nws yog ib qho tsim nyog los txheeb xyuas cov khoom ua tau zoo los ntawm kev sim ua qauv kom paub tseeb tias lub sijhawm ntev - txhim khu kev qha ua haujlwm ntawm lub cev muaj zog.
