Cov khoom siv tseem ceeb rau cov tub ntxhais lub cev muaj zog yog cov ntawv hlau silicon. Tam sim no, cov feem ntau siv yog 470, 600 thiab 800 hauv cov ntawv dov txias, ntawm cov uas 470 thiab 600 daim ntawv feem ntau siv rau hauv cov cav ua haujlwm siab.
1. Tsawg poob.
Kev poob ntawm lub hauv paus ntawm qee qhov zaus thiab lub zog sib nqus induction yog qhov qhia tseem ceeb ntawm cov ntawv hlau hluav taws xob. Kev poob ntawm lub hauv paus muaj ob ntu: kev poob hysteresis thiab kev poob eddy tam sim no. Kev poob hysteresis yog kev siv zog los ntawm kev hloov pauv magnetization ntawm lub hauv paus, uas muaj feem cuam tshuam rau cov khoom siv thiab qhov loj ntawm cov noob, thiab tuaj yeem sawv cev los ntawm thaj chaw ntawm lub voj voog hysteresis. Kev poob eddy tam sim no yog kev poob tsis kam los ntawm kev hloov pauv magnetization ntawm lub hauv paus, uas muaj feem cuam tshuam rau cov khoom siv tus kheej resistivity thiab thickness. Yog li ntawd, txhawm rau txo qhov poob ntawm lub hauv paus, cov ntawv hlau hluav taws xob muaj qhov tuab me dua thiab resistivity siab dua.
2. Kev sib nqus hluav taws xob siab.
Qhov siab dua ntawm qhov sib nqus conductivity, qhov me dua ntawm thaj tsam ntawm lub voj voog sib nqus tuaj yeem txo qis thaum lub flux tseem nyob ruaj khov, txuag cov tooj liab siv hauv qhov excitation winding thiab txo qhov loj ntawm lub cev muaj zog.
3. Cov khoom zoo laminating.
Cov phaj hlau hluav taws xob yuav tsum muaj qhov tawv tsim nyog, tsis txhob tawg yooj yim lossis mos dhau. Qhov saum npoo yuav tsum du, tiaj tus, thiab tuab sib xws (nrog rau qhov yuav tsum tau tswj qhov sib txawv ntawm phaj), uas yog qhov zoo rau kev xuas pwm thiab txhim kho cov coefficient ntawm stacking. Cov pwm tib yam tuaj yeem siv rau cov phaj hlau txias dov, thiab nws lub neej kev pabcuam tuaj yeem ntev dua piv rau cov phaj hlau kub dov. Qee cov phaj hlau hluav taws xob txias dov nrog cov txheej txheem inorganic lossis organic tuaj yeem ua rau muaj pes tsawg qhov xuas nrig ntaus ib zaug dhau ntawm cov pwm los ntawm yuav luag kaum zaug tom qab sib tsoo ib zaug. ● Tus nqi qis thiab yooj yim siv. Ntxiv rau cov kev cai saum toj no, qee lub cev muaj zog feem ntau muaj cov kev cai siab dua rau cov khoom siv hlau nplaum conductive. Piv txwv li, kev ua tsis tiav me me ntawm hlau nplaum thiab kev nthuav dav hlau nplaum me me. Cov kev cai no yog ntau yam thiab yuav tsum tau txiav txim siab tag nrho.
●Silicon hlau ntawv
Ib hom hlau sib xyaw uas muaj silicon, uas dov ua daim nyias nyias. Feem ntau hu ua silicon steel sheet. Nyob ntawm cov txheej txheem tsim khoom, nws muab faib ua cov silicon steel sheet kub dov (uas feem ntau tau raug tshem tawm) thiab cov silicon steel sheet txias dov. Cov silicon steel sheet txias dov tuaj yeem muab faib ua hom oriented thiab tsis oriented. Tam sim no, silicon steel sheet feem ntau muab los ntawm daim ntawv. Txhawm rau txhim kho cov khoom sib nqus ntawm silicon steel sheet thiab txo nws lub zog shear, cov silicon steel sheet hauv tsev tau dhau los ua kev kho mob annealing hauv lub tshuab dov.
●Tsis muaj daim ntawv hlau silicon
Lub hauv paus ntawm lub cev muaj zog siv cov ntawv hlau silicon es tsis txhob siv cov phaj hlau uas tsis muaj carbon ntau thiab cov hlau ntshiab. Qhov no yog ib qho kev nce qib tseem ceeb hauv keeb kwm. Cov ntawv hlau silicon uas tsis muaj kev poob qis tau txhim kho kev ua haujlwm ntawm lub cev muaj zog thiab txo nws qhov loj. Tam sim no, es tsis txhob siv cov ntawv hlau silicon, cov ntawv hlau silicon uas tsis muaj carbon ntau (tseem hu ua cov ntawv hlau hluav taws xob uas tsis muaj carbon ntau lossis cov ntawv hlau hluav taws xob uas tsis muaj hlau ntshiab) yog siv los ua cov hauv paus ntawm cov cev muaj zog me me vim tias cov ntawv hlau silicon uas tsim los ntawm cov thev naus laus zis niaj hnub no txawv ntawm cov phaj hlau uas tsis muaj carbon ntau thawj. Lawv tsis tsuas yog muaj lub zog magnetic induction siab xwb tab sis kuj muaj kev poob hlau zoo ib yam li cov ntawv hlau silicon. Cov cev muaj zog AC me me uas tsim thiab tsim los ntawm cov ntawv hlau silicon uas tsis muaj silicon tuaj yeem txo qhov loj me, ua kom qhov hnyav sib dua, thiab txo tus nqi. Ntxiv mus, vim tias cov ntawv hlau silicon uas tsis muaj carbon ntau mos dua, lawv tuaj yeem ua rau qhov ceev ntawm kev xuas nrig thiab ntev lub neej ntawm cov pwm. Tam sim no, cov ntawv hlau silicon uas tsis muaj carbon ntau yog siv dav ua cov khoom siv tseem ceeb rau cov cev muaj zog me me hauv cov tebchaws txawv tebchaws. Hauv cov tebchaws muaj kev lag luam, lawv siv li ntawm 50-60% ntawm tag nrho cov zis ntawm cov ntawv hlau hluav taws xob.
Tam sim no, muaj ob qhov xwm txheej uas lub Hoobkas tsav tsheb siv cov ntawv hlau tsis yog silicon. Ib qho yog tias cov ntawv hlau tsis yog silicon tom qab dov txias raug punched ncaj qha rau hauv cov ntawv, thiab tom qab ntawd kev kho mob annealing yog nqa tawm ntawm lub Hoobkas tsav tsheb; qhov thib ob yog tias cov ntawv hlau annealed muab los ntawm lub zeb hlau raug punched thiab siv ncaj qha los ntawm lub Hoobkas tsav tsheb. Cov ntawv hlau tsis yog silicon yog cov ntaub ntawv muaj zog magnetic, thiab lawv cov magnetic induction zog thiab poob yog rhiab heev rau kev ntxhov siab mechanical. Yog li ntawd, tom qab punching thiab ua ntej siv, tshem tawm kev ntxhov siab annealing yog ib qho tseem ceeb los txhim kho kev ua tau zoo magnetic. Kev kho cua sov ntawm cov ntawv hlau tsis yog silicon xav tau cov khoom siv kho cua sov tshwj xeeb, tab sis feem ntau cov Hoobkas tsav tsheb hauv peb lub tebchaws tsis muaj cov xwm txheej zoo li no. Qhov no yog ib qho teeb meem uas yuav tsum tau daws thaum siv cov ntawv hlau tsis yog silicon.
● Cov silicon thiab cov impurity silicon muaj feem cuam tshuam rau kev ua haujlwm ntawm cov ntawv hlau silicon. Tom qab ntxiv silicon rau hauv cov hlau, qhov resistivity nce ntxiv, thiab nws kuj pab cais cov pa roj carbon impurity uas ua rau muaj kev puas tsuaj. Feem ntau, thaum ntxiv hlau ntshiab nrog silicon, qhov magnetic induction intensity txo qis me ntsis, tab sis qhov poob hlau raug txo qis heev. Thaum cov silicon nce ntxiv, qhov hardness thiab brittleness nce ntxiv, uas ua rau muaj teeb meem rau dov, stamping, shearing, thiab mechanical processing. Tam sim no, cov silicon ntsiab lus ntawm cov ntawv hlau silicon feem ntau tsis ntau tshaj 4.5%. Yog tias cov silicon ntsiab lus siab dua, nws nyuaj rau ua dov thiab ua tiav.
●Tuab.Xav txog tias qhov poob tam sim no eddy hauv cov hlau core yog proportional rau lub square ntawm qhov tuab ntawm cov hlau ntawv, rau tib hom silicon hlau ntawv, qhov nyias dua qhov tuab, qhov me dua qhov poob hlau core, tab sis lub sijhawm tsim khoom ntawm cov hlau core nce thiab cov coefficient stacking txo qis. Feem ntau, cov motors siv silicon hlau ntawv nrog qhov tuab ntawm 0.5 millimeters, thiab thaum cov hlau core poob ntawm cov generators loj turbine nruj heev, 0.35 millimeters-tuab silicon hlau ntawv siv.
●Kev ntxhov siab.Thaum lub sijhawm txiav, sib dhos, lossis ntswj lub plawv hlau, kev ntxhov siab yuav tsim tawm, uas ua rau lub zog sib nqus tsis zoo thiab ua rau cov hlau poob ntau ntxiv. Hauv qhov ntau ntawm kwv yees li 1 millimeter ntawm ob sab ntawm kab txiav (tawg), thaj chaw ntxhov siab dub pom tau tsim. Feem ntau, kev kho mob annealing tuaj yeem siv los tshem tawm kev ntxhov siab thiab rov qab ua kom muaj zog sib nqus qub; kev ua haujlwm sib nqus ntawm cov ntawv hlau silicon txias-kuav los ntawm kev ua haujlwm siab yog qhov rhiab heev rau kev ntxhov siab.
