Ferrite cov hlau nplaum 'daim ntawv thov nyob rau hauv lub zog hluav taws xob tshiab (NEV)

Hlau nplaum hlauFeem ntau siv nyob rau hauv ntau yam kev thov hauv lub tsheb tshiab (Nev) vim lawv muaj peev xwm ua tau raws li qhov xav tau ntawm cov kev thauj hluav taws xob niaj hnub no. Raws li kev lag luam nev tseem loj hlob, cov hlau nplaum ferrite tau pom lawv cov khoom siv hluav taws xob, uas yog qhov tseem ceeb rau cov tshuab hluav taws xob (EVS) thiab hybrid tsheb (hevs).

1. Hluav Taws Xob Hluav Taws Xob Hauv Nevs

Ib qho ntawm thawj cov ntawv thov ntawm cov hlau nplaum ferrite hauv cov tsheb hluav taws xob tshiab yog hauv kev tsim kho hluav taws xob. Cov hlau nplaum yog dav siv nyob rau hauv cov khoom siv hlau nplaum tas mus li qub (PMSM), uas muaj txiaj ntsig zoo thiab pom nyob hauv Evs. Lub siab sib nqus lub zog thiab tshuab zog ua zog ntawm cov hlau nplaum uas muaj lawv zoo rau cov motors. Lawv pab txhawb kom txhim kho kev ua tau zoo ntawm lub cev muaj zog, muab ntau dua cov kev siv hluav taws xob, uas ncaj qha rau hauv cov tsheb zoo dua thiab kev tsav tsheb.

Hauv kev sib piv rau ntau kim tsawg-lub ntiaj teb cov hlau nplaum zoo li neodebium (ndFeb), cov hlau nplaum (ndfeb) Raws li cov hlau nplaum ferrite yog tus nqi-ua tau zoo thiab muaj txiaj ntsig, lawv muab cov nqi tsim khoom nrog kev sib tw los ntawm kev ua kom cov nqi sib tw los ntawm kev ua kom tau cov nqi ntau lawm tsis muaj kev txi lub tsheb.

2. Them lub tshuab

Lwm qhov chaw tseem ceeb uas cov hlau nplaum ferrite tau thov hauv cov tsheb hluav taws xob tshiab yog nyob rau hauv lub tshuab them nyiaj. Cov hlau nplaum tshwj xeeb, cov hlau nplaum ferrite tau siv hauv cov hloov pauv thiab cov inductors nyob rau hauv onboard them pab kiag li lawm. Lub inductive them cov txheej txheem, uas tso cai rau lub tsheb them nqi zog, cia siab rau cov hlau nplaum uas muaj hluav taws xob ua kom yooj yim. Cov hlau nplaum no yuav pab tau kev poob qis thaum lub zog hloov dua siab tshiab, ua kom cov kev them nyiaj ob leeg muaj txiaj ntsig thiab kev cog lus.

Cov hlau nplaum ferrite ua tiav lub luag haujlwm tseem ceeb hauv kev nce qib kev ua tau zoo tag nrho thiab kev txiav txim siab ntawm cov kev txiav txim siab loj rau cov neeg siv khoom thaum xaiv lub tsheb tshiab. Cov hlau nplaum qis ntawm cov hlau nplaum ferrite tso cai rau ntau cov nqi pheej yig them cov kev daws teeb meem, uas yog qhov dav dav rau kev loj hlob ntawm Nevs.

3. Kev Hloov Cov Tshuab Braking

Ntxiv rau cov hluav taws xob motors thiab them cov tshuab, cov hlau nplaum uas tau siv rau hauv cov tshuab hluav taws xob, thev naus laus zis uas tau siv zog thaum lub sijhawm nres, uas tuaj yeem rov qab siv dua. Cov hlau nplaum ferrite tau ua haujlwm hauv kev tsim kho ntawm cov tshuab hluav taws xob lub cev muaj zog siv rau hauv cov tshuab hluav taws xob hloov kho. Cov hlau nplaum cov khoom sib nqus ua kom rov zoo dua ntawm lub zog Kinetic thiab hloov pauv rau hluav taws xob lub zog, uas yog tom qab ntawd khaws cia rau hauv lub tsheb roj teeb.

Daim ntawv thov no tsis yog yuav ua rau lub tsheb txuag hluav taws xob tab sis kuj txo cov kev coj ua ntawm cov khoom siv hauv ib txwm muaj, txuas ntxiv rau lub neej ntawm cov khoom xws li nres log thiab rotors.

4. Hluav taws xob fais fab kauj (EPS)

Cov hlau nplaum ferrite yog siv hauv hluav taws xob lub tshuab hluav taws xob, uas yog cov qauv hauv cov nevs tshiab. Cov khoos kas EPS muab cov tsav tsheb nrog yooj yim rau cov kauj hauv hluav taws xob kev pab kho cov kauj vab, txo qis kev siv zog yuav tsum tig lub log. Kev siv cov hlau nplaum ferrite hauv cov khoom siv lub cev muaj zog ntawm cov qauv no ua rau cov kauj huab, txhim khu kev qha thaum ua kom muaj zog zog.

5. Zog cia Lub Nruab

Cov hlau nplaum ferrite kuj tseem siv nyob rau hauv ntau cov ntawv thov lub chaw tuav pov hwm, uas yog qhov tseem ceeb ntawm lub zog hluav taws xob hluav taws xob tshiab. Cov hlau nplaum no tuaj yeem pom hauv ntau yam ntawm cov roj teeb kev tswj hwm roj teeb (BMS) uas pab tswj hwm thiab ua kom zoo ntawm kev ua haujlwm ntawm lub tsheb roj teeb. Raws li cov roj teeb thev naus laus zis, cov hlau nplaum ferrite pab kom ntseeg tau cov kab ke no, thiab muaj peev xwm txhawb nqa lub zog loj hlob ntawm NEVS.

Cov hlau nplaum ferrite muaj ntau cov kev siv hauv kev lag luam hluav taws xob tshiab, los ntawm cov tshuab hluav taws xob mus them lub tshuab hluav taws xob, ua kom muaj zog braking, thiab lub hwj chim braking. Lawv cov nqi-ua tau zoo, txuas nrog lawv cov khoom sib nqus zoo, ua rau lawv muaj kev saib xyuas zoo nkauj rau cov nqi thiab ua tau zoo ntawm lawv cov tsheb. Raws li Nev khw txuas ntxiv mus nthuav dav, lub luag haujlwm ntawm cov hlau nplaum ferrite yog yuav nce, pab daws cov kev daws teeb meem ruaj khov thiab ua tau zoo.
