Vim nws lub cev zoo heev, cov khoom siv tshuaj zoo heev thiab cov txheej txheem zoo,Cov khoom siv hlau nplaumyog dav siv nyob rau hauv automotive precision qhov chaw, uas zoo heev txhim kho cov efficiency ntawm automotive qhov chaw. Cov khoom siv hlau nplaum yog cov khoom siv tseem ceeb ntawm kev tsav tsheb ntawm lub zog tshiab. Kev siv hluav taws xob tau dhau los ua txoj kev loj hlob ntawm kev lag luam tsheb thoob ntiaj teb, thiab cov khoom lag luam sib nqus muaj qhov chaw loj. Tsis tas li ntawd, Tuam Tshoj muaj cov peev txheej loj tshaj plaws ntawm cov peev txheej tsawg hauv ntiaj teb. Tuam Tshoj muaj loj reserves ntawm lub ntiaj teb tsis tshua muaj peev txheej, loj tso zis thiab nqi thiab cov peev txheej zoo. Nrog rau txoj kev loj hlob ntawm Tuam Tshoj lub zog tshiab tsheb kev lag luam, high-end automotive sib nqus cov ntaub ntawv thiab tuaj txog ntawm kev thov cov khoom yuav dhau los ua qhov kev loj hlob tshiab ntawm kev lag luam yav tom ntej.
Nyob rau hauv lub downstream noj tis ntawm cov khoom sib nqus, Tuam Tshoj tus tag nrho cov nyiaj siv li ntawm 50%. Nyob rau hauv lub ntiaj teb no thov qauv ntawm high-kev ua tau zoo sib nqus cov ntaub ntawv, automotive account rau 52%.
Lub cev muaj zog tsav yog ib qho ntawm peb qhov tseem ceeb ntawm lub zog tshiab. Cov khoom siv hlau nplaum yog cov khoom siv tseem ceeb rau stator thiab rotor ntawm lub cev muaj zog. Raws li cov ntaub ntawv ntawm Ministry ntawm kev lag luam thiab cov ntaub ntawv thev naus laus zis ntawm Tuam Tshoj, los ntawm Lub Kaum Ob Hlis 2019, lub peev xwm ntawm cov tsav tsheb hauv Suav teb tau mus txog 1.24 lab, ntawm cov hlau nplaum ruaj khov synchronous motors suav txog 99% ntawm kev ua lag luam. Cov hlau nplaum ruaj khov synchronous lub cev muaj zog feem ntau yog tsim los ntawm stator, rotor thiab winding, kawg npog thiab lwm yam khoom siv tshuab. Qhov zoo thiab kev ua tau zoo ntawm cov ntaub ntawv sib nqus ncaj qha txiav txim siab cov cim tseem ceeb xws li kev siv hluav taws xob thiab kev ruaj ntseg ntawm cov hlau nplaum ruaj khov tsav lub cev muaj zog.
Automotive sib nqus cov ntaub ntawv yog siv los tsav lub cev muaj zog ntawm lub zog tshiab. Kev tsav tsheb ntawm lub zog tshiab tsheb yog lub tshuab hluav taws xob mus ncig ua haujlwm ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction. Nws yog siv los hloov hluav taws xob hluav taws xob mus rau lub tshuab hluav taws xob thiab nqus hluav taws xob los ntawm cov hluav taws xob hluav taws xob thaum lub sijhawm ua haujlwm. Tso tawm txhua lub zog rau cov tshuab hluav taws xob. Cov hlau nplaum ruaj khov stepping rov qab lub cev muaj zog yog tsim los ntawm stator, rotor thiab winding, kawg npog thiab lwm yam khoom siv tshuab. Ntawm lawv, qhov zoo thiab kev ua tau zoo ntawm stator thiab rotor cores ncaj qha txiav txim siab tus nqi ntawm cov cim tseem ceeb xws li kev siv hluav taws xob thiab kev ruaj ntseg ntawm lub cev muaj zog, suav txog 19% thiab 11% ntawm tag nrho cov nqi ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog feem. Cov khoom siv hlau nplaum feem ntau yog siv rau hauv lub tsheb lub cev muaj zog rotors. Los ntawm cov khoom siv, cov ntaub ntawv sib nqus thiab cov ntaub ntawv silicon steel yog cov ntaub ntawv tseem ceeb uas txiav txim siab tus nqi ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog, suav txog 30% thiab 20% ntawm tag nrho cov nqi feem.
Tam sim no, hom tsav tsheb siv nyob rau hauv lub zog tshiab tsheb yog feem ntau AC asynchronous motors thiab ruaj khov hlau nplaum synchronous motors. Nws qhia tau hais tias muaj kev nce zuj zus txhua xyoo. Raws li lub zog ntawm lub zog tshiab tsheb, cov hlau nplaum ruaj khov synchronous lub cev muaj zog (PMSM) muaj cov yam ntxwv ntawm lub zog siab ceev, txhim khu kev lag luam thiab kev ua haujlwm nrawm, piv nrog lwm hom motors. Nws tuaj yeem muab lub zog tso zis ntau dua nyob rau hauv tib qhov loj thiab ntim, thiab yog hom zoo tagnrho lub cev muaj zog rau lub zog tshiab. Ntawm lawv, Nyiv thiab Kaus Lim Qab Teb tau txais cov hlau nplaum ruaj khov synchronous tshuab, thiab Europe txais AC asynchronous tshuab. Cov hlau nplaum ruaj khov synchronous lub cev muaj zog (PMSM) tau dhau los ua lub tshuab muag khoom siv dav tshaj plaws hauv Suav teb lub zog tshiab tsheb los ntawm kev tsim txiaj ntawm nws lub zog siab, tsis muaj zog, me me thiab qhov hnyav.
