Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm lub ntiaj teb tshiab lub zog tsheb kev lag luam, tsav tsheb tshuab, raws li ib tug ntawm cov tseem ceeb Cheebtsam, yog undergoing unprecedented transformation thiab innovation. Los ntawm cov hlau nplaum ruaj khov synchronous motors mus rau hub motors, los ntawm cov khoom siv tshiab rau kev tswj xyuas kev txawj ntse, tsav lub tshuab tsav tsheb nrawm nrawm rau kev ua tau zoo dua, sib dua, sib xyaw ua ke, thiab kev txawj ntse, muab kev txhawb zog rau kev txhim kho kev ua haujlwm thiab kev tswj cov nqi ntawm cov tsheb tshiab.
Nyob rau hauv lub backdrop ntawm kev txuag hluav taws xob thiab emission txo, kev ua haujlwm siab ntawm cov tsav tsheb tau dhau los ua kev pom zoo hauv kev lag luam. Cov hlau nplaum ruaj khov synchronous motors, vim lawv lub zog muaj zog thiab kev ua haujlwm siab, tam sim no ua tus thawj coj hauv khw. Raws li cov ntaub ntawv kev lag luam, xyoo 2024, lub peev xwm ntawm cov hlau nplaum ruaj khov synchronous motors hauv Suav teb suav txog ntau dua 90%, nrog kev ua haujlwm siab tshaj plaws tshaj 97%. Txawm li cas los xij, kev hloov pauv ntawm tus nqi thiab cov teeb meem kev ruaj ntseg ntawm cov khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb tau ua rau cov tuam txhab ua kom nrawm rau kev tshawb fawb thiab kev tsim kho lwm txoj kev daws teeb meem. Cov hlau nplaum ruaj khov pab synchronous reluctance lub cev muaj zog (PMa-SRM) thev naus laus zis siv hauv Tesla Model 3 txo cov nqi ntawm lub ntiaj teb tsis tshua muaj los ntawm kev ua kom zoo rau kev tsim hluav taws xob sib nqus, yog li txo cov nqi thaum tswj kev ua haujlwm siab. Cov tuam txhab lag luam hauv tsev xws li BYD thiab Jingjin Electric tseem tab tom txhim kho qis- hnyav hnyav- hauv ntiaj teb lossis tsis tshua muaj - ntiaj teb- cov hlau nplaum tsis muaj zog. BYD's "yim-hauv-ib qho" hluav taws xob tsav, piv txwv li, nce kev ua haujlwm ntawm lub cev muaj zog mus rau 96.5%, nrog qhov kev ua haujlwm nruab nrab ntawm 89% raws li NEDC cov xwm txheej.
Daim ntawv thov ntawm silicon carbide (SiC) cov khoom siv hluav taws xob tau txuas ntxiv kev txhim kho hauv kev ua haujlwm ntawm lub cev muaj zog. Piv rau IGBTs ib txwm muaj, SiC cov cuab yeej tuaj yeem txo qis kev tswj hluav taws xob los ntawm ntau dua 50% thiab nce kev ua haujlwm zaus los ntawm 3-5 zaug. Huawei's DriveONE hluav taws xob tsav system siv tag nrho SiC modules, ua tiav qhov kev ua haujlwm siab tshaj plaws ntawm 92%, 3 feem pua cov ntsiab lus siab dua qhov nruab nrab ntawm kev lag luam. Nws tau kwv yees tias los ntawm 2026, ntau dua 30% ntawm high-end hluav taws xob tsheb yuav siv SiC hluav taws xob tsav tshuab.
Raws li lub zog tsav tsheb tseem ceeb rau cov cuab yeej siv niaj hnub tsim khoom, hluav taws xob servo systems yog ib qho tseem ceeb hauv kev siv tshuab rau lub Hoobkas automation. Nrog rau txoj kev loj hlob sai ntawm kev lag luam niaj hnub, kev xav tau ntau dua tau muab tso rau hauv cov tshuab hluav taws xob servo niaj hnub. Daim ntawv no piav qhia luv luv txog cov txheej txheem kev txhim kho thiab cov qauv ntawm cov tshuab hluav taws xob servo, qhia txog qhov tseem ceeb ntawm kev txhim kho siab -kev ua haujlwm ruaj khov hlau nplaum synchronous lub cev muaj zog (PMSM) servo systems thiab qhia txog ntau yam teeb meem. Nws tseem tshuaj xyuas qhov kev tshawb fawb tam sim no ntawm siab -kev ua tau zoo PMSM servo systems thiab sib tham txog lawv cov kev cia siab rau daim ntawv thov.
