Nyob rau hauv 2016, qhov muaj peev xwm muaj peev xwm ntawm lub zog tshiab nws pib cav tau ze li ntawm 600,000 units, thiab cov tshuab hluav taws xob synchronous tas li rau 77%.
Raws li cov ntaub ntawv ntawm Thawj Fais Kev Tshawb Fawb Lub Tsev Kawm Ntawv, qhov muaj peev xwm muaj peev xwm ntawm lub zog tshiab tsheb tsav lub zog txog 595,000 units nyob rau hauv 2016, uas zoo sib xws rau cov khoom tso tawm ntawm cov tsheb tshiab. Raws li hom cav, daim npliag magnet synchronous lub cev tseem yog lub ntsiab, nrog ntau dua 450,000 units, accounting rau 77%; AC asynchronous tsav lub cav muaj peev xwm ntau tshaj 140 lab, accounting rau 23%; ua raws li kev sib tw sib xyaw synchronous, Kev sib txhuam / ruaj khov magnet DC tsav nruab nrab ntawm ze li ntawm 2,000 units, accounting rau tsuas yog 1%. (Cov roj teeb tej ntaub ntawv pom: 2016 roj teeb xa tuaj cuag 28Gwh BYD / CATL / Waterma / Guo Xuan txheeb xyuas rau 66%)
Nws muaj nqis taw tawm tias hom kev lag luam nyob hauv thaj tsam ntawm cov zog tshiab tsheb yog feem ntau AC motors, thiab muaj tsawg tus qauv muaj peev xwm nrog DC motors. Qhov sib txawv ntawm qhov sib txawv nruab nrab ntawm ob yog tias qhov hluav taws xob sab nraud txawv: ib qho yog DC thiab lwm tus yog AC. Siv lub ntsiab lus ntawm DC motor kuj yooj yim, tab sis cov qauv tsis yooj yim thiab tsis yoojyim, thiab txoj cai ntawm AC lub cev muaj zog tab sis cov qauv no kuj yooj yim thiab yooj yim rau kev tswj hwm. DC tsav muaj kev ceev kev tswj cov kev ua tau zoo, thiab ua tau zoo li kev ua tau zoo thiab txoj kev ua tsis sib haum ceev tsis tau raws li qee qhov kev mob, kom qhov kev cai tswj ceev yog dav; Lub sijhawm pib ua haujlwm tau zoo, qhov kev hloov ntawm kev ua haujlwm yuav ua kom pom thiab muaj kev lagluam, thiaj li muaj tsawg zog hauv lub zog tshiab (ze li txhiab) Lub peev xwm ntawm Taiwan yog siv los ua cov tsheb loj xws li neeg tsav tsheb. efficiency, kuj suab nrov thiab zoo heev, yog li nws yog dav siv nyob rau hauv lub tshav pob ntawm cov tshiab zog neeg caij tsheb.
Nyob rau xyoo tag los, muaj tsawg tsawg tus qauv nruab nrog ob lossis ntau tsav tsheb nyob rau hauv txoj kev faib hluav taws xob tshiab. Ntawm lawv, cov qauv ntawm tus neeg caij tsheb npav tshaj 25,000, thiab cov motors muaj ntau tshaj 50,000. Nyob rau ntawm lub tuam txhab tsheb, tagnrho cov neeg tsav tsheb thiab tsheb tshwj xeeb yog 34,000, thiab hom kev lag luam muaj feem ntau nyob rau hauv cov chaw txuas hluavtaws uas tsis tu ncua.
Ntawm lawv, nyob rau hauv thaj tsam ntawm lub zog tshiab cov neeg tsav tsheb thiab cov tsheb khiav lag luam, qhov muaj peev xwm ntawm cov neeg tsav tsheb txheeb xyuas tau rau 57% thiab 43% feem. Nyob rau hauv lub tshav pob ntawm tshiab lub zog coj mus muag tsheb, tag nrho cov muaj peev xwm ntawm tsav tsheb nyob rau hauv 2016 txog 253,500 units, tsuas yog raws li tas mus li hlau nplaum synchronous motors, nrog ib tug me me ntawm DC motors faib. Muab piv nrog cov tsheb npav tshiab thiab hluav taws xob ntshiab, qhov muaj peev xwm muaj peev xwm ua tau zoo li cov qauv ntawd. Qhov muaj peev xwm ntawm cov cav fais fab yog ze li ntawm 100,000 units, deb tsawg dua qhov muaj peev xwm ntawm 152,000 lub tsheb npav tshiab. Lub peev txheej ntawm ob lub qauv yog 26% feem. Thiab 17%.
Qhov txawv yog tias hom tsav motors rau ntshiab fais tsheb yog mas concentrated rau AC asynchronous motors thiab cov hlau nplaum synchronous mus tas li. Qhov muaj peev xwm ntawm ob hom kev siv zog yog khaws cia ntawm ib qho piv txwv ntawm kwv yees li 3: 2. Cov tsav tsheb ntawm kev tsav tsheb rau ib tus qauv tsuas yog ib qho xwb. Hauv thaj chaw tsheb npav tshiab, muaj ntau tshaj 4,000 tus neeg tsav tsheb uas muaj ob lub tsheb tsav (dual drive), uas yog cov qauv hauv cov qauv hluav taws xob ntshiab xws li BYD, Changjiang thiab Shenwo.
Raws li lub tuam txhab tshwj xeeb, raws li cov peev xwm ua tau 2016, sab saum toj 15 tuam ntxhab muaj ntau tshaj 10,000 ntawm cov tsav tsheb. Ntawm lawv, tsuas BYD, uas tau ntsia ntau tshaj 100,000 units, nyob rau hauv daim ntawv teev npe, accounting rau 23.2%. Secondly, BAIC. Cangzhou Hengyi Electric, Yutong, Anhui Juyi, thiab United Auto Electronics muaj ib qho muaj peev xwm ntawm 20,000 units. Tus naj npawb ntawm cov neeg tsav tsheb nyob rau sab saum toj tau nce txog 300,000 units, accounting rau ze li 50% ntawm tag nrho, thiab cov concentration ntawm ntau lawm muaj peev xwm. Feem ntau ntawm cov tuam txhab tsim muaj cov khoom lag luam yog cov khoom siv hluav taws xob sib txuas ntawm cov hluav taws xob, thiab cov hom kev lag luam nrog Beiqi, Jiangling thiab Jingjin hluav taws xob yog them nrog cov khoom siv hluav taws xob sib txuas ntawm cov synchronous thiab AC asynchronous motors. Ntawm lawv, cov hluav taws xob ntawm Jiangling tsav motors yog cov AC asynchronous cov hluav taws xob. Muaj ntau tsawg daim hlau npliag hluavtaws ua ke. Cov hom hluav taws xob hauv Zhangzhou Hengyi kuj yog cov AC asynchronous engine feem ntau.
Ntawm sab saum toj 15 tsav tsav tsheb nyob rau hauv lub tshav pob ntawm cov tshiab zog neeg caij tsheb, qhov nruab tau muaj peev xwm tau txog 111,000 units, accounting rau 74%, nrog ib qib siab concentration. Tsuas yog ob lub tuam txhab ua rau AC asynchronous motors. Cov hom motors uas ua los ntawm lwm cov tuam txhab muaj concentrated nyob rau hauv cov hlau nplaum synchronous tas li. Nyob rau hauv lub tshav pob ntawm cov tsheb tshwj xeeb, ntawm cov khoom lag luam saum toj kawg nkaus 15, kev tsim kho muaj peev xwm yog 86,000 units, accounting rau cov tsheb tshwj xeeb. 86% ntawm tag nrho cov muaj peev xwm tsim, uas 5 thiab 10 tuam txhab tau tsim cov AC asynchronous motors thiab cov hlau nplaum synchronous mus tas li.
