Raws li cov khoom tseem ceeb ntawm lub zog tshiab tsheb (NEV) tsav lub cev muaj zog, cov khoom siv kho vajtse ncaj qha txiav txim siab lub cev muaj zog thiab tus nqi. Qhov yooj yim version no tsom rau cov hauv paus ntsiab lus ntawm kev xaiv cov khoom siv, cov khoom siv tseem ceeb ntawm cov khoom siv, thiab cov tswv yim ua kom zoo tshaj plaws rau cov khoom siv hluav taws xob tshiab.
1. Cov ntsiab lus tseem ceeb ntawm kev xaiv cov khoom siv
Kev xaiv cov khoom siv yuav tsum ua raws li plaub lub hauv paus ntsiab lus: kev ua tau zoo sib xws (ua raws li kev ua haujlwm ntawm lub cev muaj zog), kev ntseeg siab (ua tau raws sijhawm ntev -} cov kev pabcuam hauv lub sijhawm), kev tswj tus nqi (tso kev ua tau zoo thiab kev lag luam), thiab kev ruaj khov (thaum ua ntej rov ua dua tshiab, qis- cov ntaub ntawv muaj kuab paug).
2. Kev xaiv cov khoom siv rau cov khoom tseem ceeb
2.1 Stator thiab Rotor
Cov ntaub ntawv tseem ceeb yog cov ntawv hlau hluav taws xob (txias- dov tsis yog- taw qhia rau cov motors zoo tib yam, taw qhia rau siab - kev ua tau zoo motors). Amorphous alloys yog cov kev hloov tshiab nrog qis hlau poob. Rotor mus tas li hlau nplaum tsuas yog siv NdFeB; siab -kev ua tau zoo ferrite thiab MnAlC alloys yog tus nqi- muaj txiaj ntsig zoo los txo qis kev cia siab hauv ntiaj teb.
2.2 Lub cev muaj zog
Aluminium alloys (A356, ADC12) yog thawj qhov kev xaiv, suav txog ntau dua 80% ntawm kev ua lag luam, vim lub teeb yuag thiab zoo cua sov dissipation. cam khwb cia hlau yog siv rau kev lag luam tsheb loj loj, thaum cov ntaub ntawv sib xyaw yog txwv rau siab -kawg qhov kev sim.
2.3 Lub cev muaj zog ncej
Nruab nrab thiab qis - lub zog tsav siv 45 # carbon steel; siab -lub zog, siab- cov motors ceev tau txais cov hlau hlau (40Cr, 20CrMnTi) nrog kev kho saum npoo (carburizing, quenching) los txhim kho hnav tsis kam.
2.4 Cov cua txias
Tooj liab (oxygen- dawb tooj liab T2) yog cov khoom tseem ceeb rau kev ua haujlwm siab; aluminium yog siv nyob rau hauv qis - fais fab motors los txo cov nqi. Hairpin windings thiab nanocomposite rwb thaiv tsev cov ntaub ntawv txhim kho kev ua tau zoo thiab kub ua hauj.
2.5 Fasteners
Carbon steel bolts rau cov xwm txheej dav dav, alloy steel bolts rau siab -kub / vibration ib puag ncig, thiab stainless hlau (304, 316) rau corrosive ib puag ncig, nrog rau kev kho deg los txhim kho corrosion.
3. Cov Tswv Yim Txhim Kho Tus Nqi
Tus nqi optimization sib npaug kev ua tau zoo thiab kev lag luam los ntawm tsib qhov kev ntsuas tseem ceeb, qhov twg Xiamen Jiaxin Precision Metal Co., Ltd. (Jiaxin) muaj qhov pom tseeb zoo, zoo kawg nkaus ua ke cov kev ntsuas no rau hauv nws cov haujlwm:
Ua kom zoo xaiv cov khoom siv: Siv tus nqi- lwm txoj kev zoo (xws li ferrite es tsis yog NdFeB) thiab cov khoom siv hauv zos los txo cov nqi yuav khoom. Raws li ib tug ua precision hardware stamping thiab pwm ua lag luam nyob rau hauv Fujian, Jiaxin muaj ntev -lub sij hawm ruaj khov kev koom tes nrog zoo-paub raw khoom lwm tus neeg xws li Baosteel thiab Tuam Tshoj Aluminium Luoyang tooj liab kev lag luam, tsim ib tug ruaj ntseg thiab ruaj khov raw khoom muab system muab cov neeg muas zaub nrog siab - cov ntaub ntawv raw ntawm tus nqi tsim nyog. Nws kuj tseem tshwj xeeb hauv cov ntawv hlau hluav taws xob hluav taws xob (kev taw qhia thiab tsis yog -oriented) thiab precision stamping qhov chaw, raug txuam nrog cov khoom siv hluav taws xob tshiab uas xav tau thaum tswj cov nqi.
Txhim kho kev siv cov khoom siv: Ua kom zoo tshaj plaws stamping nesting thiab dawb paug tsim kom txo tau cov khoom pov tseg. Nruab nrog ntau yam ntawm siab -tonnage presses (16t mus rau 400t) thiab cov khoom siv pwm ua haujlwm siab heev, Jiaxin muaj peev xwm stamping thiab pwm tsim, optimizing lub zes layout ntawm stator thiab rotor silicon steel los xij kom siv cov khoom siv thiab txo cov khoom pov tseg, thaum nws cov khoom siv ua kom zoo.
Optimize processing technology: Txais cov cuab yeej siv hluav taws xob thiab kev kho cua sov kom zoo los txhim kho kev tsim khoom. Jiaxin muaj cov cuab yeej tsim khoom thiab kev sim siab, nrog rau 1,800 square metres ntawm Chav Kawm 1,000 thiab 10,000 kev cob qhia huv. Nws siv cov cuab yeej siv hluav taws xob ntau lawm thiab cov txheej txheem kho cua sov kom ua kom cov khoom siv ntau dua 50%, txo cov nqi zog, thiab xyuas kom muaj kev sib xws thiab zoo ntawm cov khoom siv hluav taws xob tshiab, nrog kev nplua nuj nyob rau hauv precision stamping thiab pwm tsim los ua kom zoo dua cov kauj ruam thiab txo cov nqi.
Txhim kho kev tswj cov saw hlau kom zoo: Tsim kom ntev - lub sij hawm muab kev koom tes nrog cov neeg muag khoom thiab kev yuav khoom hauv nruab nrab kom txo tau cov nqi thauj khoom thiab kev yuav khoom. Kev vam khom rau Xiamen qhov kom zoo dua li lub teb chaws cov khoom lag luam kev tsim kho tshiab thiab daim ntawv thov ua qauv qhia lub nroog, Jiaxin tau ua kom zoo dua nws cov khoom siv sib txuas, tsim kom ntev ntev - kev koom tes nrog cov neeg muab khoom tseem ceeb, thiab tau txais kev yuav khoom hauv nruab nrab kom txo tau cov nqi thauj khoom thiab kev yuav khoom. Raws li Hong Kong- nqis peev siab- thev naus laus zis kev lag luam nrog ntau tshaj 20 xyoo ntawm kev txhim kho, nws muaj cov khoom lag luam paub tab tswj xyuas kom ruaj khov thiab muaj txiaj ntsig zoo.
Optimize structural design: Txais kev sib xyaw ua ke thiab hollow cov qauv los txo cov khoom siv thiab ua kom yooj yim. Nrog muaj zog R & D thiab tsim muaj peev xwm, Jiaxin muaj ntau tus nqi siab - patents tus nqi thiab ua cov txheej txheem thev naus laus zis hauv kev lag luam, uas tuaj yeem muab cov kev tsim qauv tsim kho kom zoo rau cov khoom siv hluav taws xob tshiab (xws lilub cev muaj zog, stators, thiab rotors) raws li cov neeg siv khoom xav tau, txais yuav cov qauv kev sib xyaw ua ke thiab hollow los txo cov khoom siv thiab ua kom yooj yim, thiab ua tiav cov nqi kho kom zoo thaum ua kom cov khoom ua tau zoo.
4. Cov kev sib tw tseem ceeb thiab yav tom ntej Trends
Cov kev sib tw suav nrog kev ua tau zoo- qhov tsis sib xws ntawm tus nqi, cov khoom siv tseem ceeb tsis ruaj khov, thiab kev siv thev naus laus zis sai. Cov kev xav yav tom ntej tsom mus rau siab -kev ua haujlwm qis- cov khoom siv tshiab, cov khoom siv sib xyaw ua ke- qauv tsim, thiab cov khoom siv ntse ntse thiab kev ua tiav.
Xaus
Kev xaiv cov khoom siv thiab kev ua kom zoo dua yog qhov tseem ceeb rau NEV lub cev muaj zog kho vajtse. Los ntawm kev ua raws li cov hauv paus ntsiab lus thiab kev siv cov tswv yim tsim nyog, cov tuam txhab tsim khoom tuaj yeem tsim tau siab -kev ua tau zoo, qis- cov khoom raug nqi, txhawb kev txhim kho kom ruaj khov ntawm kev lag luam lub zog tshiab.
