Nyob rau hauv xyoo tas los no, lub ntiaj teb ib puag ncig tau ntsib cov teeb meem loj dua, thiab nws tseem yuav tshwm sim los txhim kho lub cev muaj zog thiab txo lub cev muaj zog. Tsis tas li ntawd, nrog kev nce ntawm cov thev naus laus zis tshiab, kev siv ib puag ncig thiab cov kev xav tau tshwj xeeb ntawm cov motors kuj tau hloov pauv, xav tau cov motors me nrog cov zis ntau dua. Yuav kom ua tau raws li cov kev cai no, nce kev sib hloov ceev ntawm lub cev muaj zog tau dhau los ua ib qho kev daws teeb meem, thiab txawm tias cov motors me me, lub zog tso zis tuaj yeem nce ntxiv los ntawm kev sib hloov ceev. Txawm li cas los xij, raws li qhov nrawm nce, cov hlau poob ntawm lub cev muaj zog tseem yuav nce nrawm, ua rau txo qis hauv kev ua haujlwm.
Cov tub ntxhais lub cev muaj zog feem ntau yog ua los ntawm cov hlau tsis muaj hluav taws xob, thiab cov qauv phaj tuab yog 0.5 hli thiab 0.35 hli. Cov khoom siv no raug xaiv vim tias qhov kev sib hloov ceev ceev ntawm lub cev muaj feem cuam tshuam nrog lub siab zaus ntawm cov hlau nplaum hauv cov tub ntxhais hlau, thiab cov hlau tsis zoo ntawm cov hluav taws xob steel phaj yuav nce ntxiv nrog qhov ntau zaus. Qhov no feem ntau yog vim eddy tam sim no poob. Eddy qhov poob tsis ntev los no tuaj yeem qhia tau los ntawm qhov xwm txheej ntawm qhov sib nqus, qhov sib nqus flux ceev, thiab phaj tuab.
Txhawm rau txhawm rau txhawm rau nce qhov poob ntawm cov hlau los ntawm ntau zaus, tib neeg tau tsim cov nplooj ntawv hluav taws xob ultra-thin, uas tuaj yeem txo qhov nce ntawm qhov poob tam sim no ntawm cov zaus thaum tswj xyuas qhov siab saturation magnetic flux ntom thiab lwm yam ntxwv ntawm cov tsis- oriented hluav taws xob steel ntawv. Nws tau tshaj tawm tias cov nplooj ntawv hluav taws xob ultra-nyias yog tsim los ntawm rov dov cov ntawv uas tsis yog-oriented hluav taws xob steel ntawv. Txoj kev loj hlob ntawm no ultra-nyias hluav taws xob steel ntawv yuav tsum tau ua lub luag hauj lwm zoo nyob rau hauv teb xws li me me high-speed electric motors.
Txawm li cas los xij, tseem muaj teeb meem hauv kev ua cov ntawv dav dav ultra-nyias hluav taws xob steel ntawv, thiab yuav ua li cas siv ultra-thin hluav taws xob hlau los ua cov hlau loj loj tau dhau los ua qhov teeb meem. Vim li no, tib neeg tau tsim ib qho hluav taws xob tsis tshua muaj hluav taws xob hlau sawb coil core hu ua "qhov txhab laminated core", uas tuaj yeem ua tiav lub hom phiaj ntawm lub cev muaj zog loj txawm tias qhov dav yog nqaim. Hom hlau tub ntxhais no muaj lub phaj tuab ntawm tsuas yog 0.08mm, uas nyias nyias thiab tuaj yeem ua rau hauv cov duab coiled. Los ntawm kev nce tus naj npawb ntawm windings, nws tuaj yeem ua tiav qhov loj dua qhov txheeb ze rau cov kev taw qhia radial.
Feem ntau, "qhov txhab mob" yog hais txog cov tub ntxhais uas tsim los ntawm winding ib daim ntawv hluav taws xob uas twb muaj lawm, thaum "qhov txhab laminated core" yog hais txog cov tub ntxhais uas tsim los ntawm winding lub ultra-thin hluav taws xob steel sawb nrog nyias phaj tuab. Hom ntawm cov tub ntxhais no tswj kev rwb thaiv tsev interlayer los ntawm winding ib qho hluav taws xob tsis tshua muaj hluav taws xob steel sawb nrog cov txheej txheej insulating.
Tam sim no, txawm hais tias ib txoj kev winding ib tug hlau tub ntxhais nrog ib tug nyias nyias amorphous cov ntaub ntawv tau tsim, lub interlayer rwb thaiv tsev kev ua tau zoo ntawm cov tub ntxhais hlau tsis tuaj yeem khaws cia vim hais tias cov khoom amorphous nws tus kheej tsis muaj txheej txheej insulating. Nyob rau hauv sib piv, lub qhov txhab laminated cores raug mob siv tsis tshua muaj hluav taws xob hlau strips nrog insulating txheej, thiaj li hais tias interlayer rwb thaiv tsev yuav tsum tau khaws cia.
Cov kws tshawb fawb xws li Wakabayashi Daisuke ntawm University of Arts thiab Sciences hauv Nyij Pooj tau kawm txog kev hloov pauv los ntawm cov qauv tseem ceeb los ntawm kev sib piv cov qauv ntawm lub qhov txhab laminated core thiab cov tsoos laminated core. Nyob rau tib lub sijhawm, los ntawm kev ntsuas qhov txhab laminated cores ua los ntawm ultra-thin hluav taws xob steel strips ntawm cov thicknesses sib txawv, qhov zoo tshaj plaws thickness thiab manufacturing tej yam kev mob rau ntxiv txo hlau poob tau tshawb.
Lawv ntseeg hais tias lub qhov txhab laminated cores ua los ntawm cov tshiab tsim ultra-thin hluav taws xob steel sawb muaj cov khoom sib nqus piv rau cov pa laminated cores. Los ntawm kev nce tus naj npawb ntawm windings, radial loj tuaj yeem ua tiav, uas ua rau txo qis thiab qhov loj ntawm cov tshuab hluav taws xob hloov hluav taws xob ceev.
GO Hluav Taws Xob Hlau
Yog li ntawd, tib neeg tuaj yeem muab cov cores hlau ntawm ntau qhov sib txawv, ntxiv rau kev nthuav dav ntawm kev siv tau zoo ntawm ultra-thin hluav taws xob steel ntawv. Tshwj xeeb, cov tub ntxhais laminated nrog lub phaj tuab ntawm 0.08mm tuaj yeem tswj cov yam ntxwv ntawm cov hlau tsis tshua muaj hlau tsis zoo thiab cov hlau nplaum sib nqus permeability nyob rau hauv ntau zaus ntawm 50Hz txog 1kHz thiab yog cov khoom siv tseem ceeb tshaj plaws rau kev txo qis hysteresis poob thiab eddy tam sim no poob.
Nyob rau hauv qhov ntau zaus tshaj 1kHz, vim qhov nce ntawm eddy tam sim no poob, cov khoom xaiv ntawm 0.05mm tuaj yeem txiav txim siab. Cov kws tshawb fawb tau hais tias lawv npaj yuav ua cov txheej txheem laminated hlau ua los ntawm cov hlau tsis tshua muaj hluav taws xob nyias mus rau hauv cov qauv ntawm lub cev muaj zog stator kom paub meej ntxiv cov yam ntxwv ntawm stator thiab nws cov txiaj ntsig ntawm kev siv lub cev muaj zog.
