GNEE Steel Non-Oriented Silicon Steel Core

Rau cov hlau nplaum ruaj khov lub cev muaj zog, cov tub ntxhais hlau yog ib feem tseem ceeb ntawm lub cev muaj zog, rau kev xaiv cov khoom siv hlau, nws yog ib qho tsim nyog yuav tau xav txog seb qhov permeability tuaj yeem ua tau raws li qhov xav tau ntawm cov hlau nplaum ruaj khov. Raws li ib txwm muaj, cov hlau nplaum ruaj khov motors xaivhluav taws xob hlauRaws li cov khoom siv hlau, lub ntsiab yog vim li cas cov hlau hluav taws xob muaj qhov ua tau zoo dua ntawm cov hlau nplaum permeability. Kev xaiv ntawm lub cev muaj zog hlau cov khoom siv tseem ceeb heev rau kev ua haujlwm ntawm tag nrho cov hlau nplaum lub cev muaj zog thiab cov nqi tswj ntawm lub cev muaj zog. Thaum lub tshuab hlau nplaum ruaj khov yog tsim, sib sau ua ke thiab ua haujlwm, qee qhov kev ntxhov siab yuav raug tsim ntawm cov tub ntxhais hlau. Lub hav zoov ntawm kev ntxhov siab yuav cuam tshuam ncaj qha rau permeability ntawm cov ntawv hlau hluav taws xob, uas ua rau muaj qhov sib txawv ntawm qhov sib nqus permeability, qhov ua tau zoo ntawm cov hlau nplaum ruaj khov lub cev muaj zog yuav raug txo, thiab yuav ua rau lub cev tsis muaj zog.

Hauv kev tsim thiab tsim cov hlau nplaum ruaj khov motors, kev xaiv thiab siv cov ntaub ntawv tau dhau los ua ntau thiab xav tau, thiab txawm tias ze rau cov qauv txwv thiab qib ntawm cov khoom siv. Raws li cov khoom siv hlau tseem ceeb ntawm cov hlau nplaum tas mus li, cov hlau hluav taws xob yuav tsum ua kom tau raws li qhov yuav tsum tau muaj tseeb hauv cov ntaub ntawv siv thev naus laus zis thiab kev suav cov hlau siv kom raug, txhawm rau ua kom tau raws li qhov xav tau tiag tiag.

Cov txheej txheem tsim lub cev muaj zog siv los suav cov yam ntxwv ntawm cov khoom siv hluav taws xob ntawm cov hlau hluav taws xob yog qhov tsis raug, vim tias cov qauv no feem ntau yog rau cov xwm txheej, cov txiaj ntsig suav yuav muaj qhov sib txawv loj. Yog li ntawd, yuav tsum muaj ib txoj kev xam tshiab kom raug xam qhov sib nqus permeability thiab hlau poob ntawm hluav taws xob steel nyob rau hauv cov kev mob ntawm kev nyuaj siab, thiaj li hais tias daim ntawv thov theem ntawm hlau core cov ntaub ntawv yog siab dua, thiab cov kev ua tau zoo qhia xws li cov efficiency ntawm cov hlau nplaum mus tas li. lub cev muaj zog tuaj yeem ncav cuag qib siab dua.

Los ntawm qhov pom ntawm daim ntawv ntawm cov hlau nplaum ruaj khov lub cev muaj zog stator core kev ntxhov siab, cov peev txheej ntawm nws tsim muaj xws li xuas nrig ntaus, riveting, lamination, casing cuam tshuam los ua ke, thiab lwm yam. Rau lub rotor ntawm cov hlau nplaum ruaj khov lub cev muaj zog, nws qhov kev ntxhov siab feem ntau suav nrog thermal stress, centrifugal quab yuam, electromagnetic quab yuam, thiab lwm yam yuav tsum tau teem rau hauv lub hauv paus ntawm lub rotor. Yog li ntawd, centrifugal kev nyuaj siab yog qhov tseem ceeb tshaj plaws ntawm kev ntxhov siab. Lub stator core kev ntxhov siab tshwm sim los ntawm kev cuam tshuam los ntawm kev sib koom ua ke ntawm cov hlau nplaum tas mus li lub cev muaj zog feem ntau muaj nyob rau hauv daim ntawv ntawm kev ntxhov siab compressive, uas yog concentrated nyob rau hauv lub quab ntawm stator core ntawm lub cev muaj zog, thiab cov kev taw qhia kev ntxhov siab yog circumferential.

Kev hloov pauv ntawm qhov sib nqus ntawm qhov tseem ceeb ntawm lub tshuab hlau nplaum ruaj khov yog tshuaj xyuas. Nyob rau hauv lub zog ntawm saturation, qhov sib nqus ceev ntawm lub rotor reinforcing bar thiab cov hlau nplaum sib cais choj tsis hloov ntau. Qhov sib nqus ntom ntom ntawm stator thiab lub ntsiab sib nqus ntawm lub cev muaj qhov hloov pauv loj heev. Qhov no tseem tuaj yeem piav qhia txog cov nyhuv ntawm cov nyhuv ntawm cov khoom siv hluav taws xob ua kom ceev thiab sib nqus ntawm lub cev muaj zog tas mus li thaum lub sijhawm ua haujlwm.

Vim tias cov nyhuv ntawm kev ntxhov siab, qhov kev ntxhov siab ntawm lub stator quab yuam ntawm cov hlau nplaum ruaj khov lub cev muaj zog yuav muaj zog, qhov poob ntawm qhov no yog qhov loj, thiab qhov ua tau zoo yog qhov tsis zoo. Muaj ib qho teeb meem loj hlau poob hauv stator yoke ntawm cov hlau nplaum tas mus li lub cev muaj zog, tshwj xeeb tshaj yog cov hlau poob hauv qhov sib koom ua ke ntawm stator hniav yoke yuav ua rau muaj kev ntxhov siab ntau tshaj plaws. Los ntawm kev suav, nws pom tau hais tias cov hlau noj ntawm cov hlau nplaum ruaj khov lub cev muaj zog nce 40% -50% vim yog kev cuam tshuam ntawm tensile kev nyuaj siab, uas tseem yog qhov xav tsis thoob, yog li nws kuj ua rau muaj kev nce ntxiv hauv tag nrho cov kev poob. mus tas li hlau nplaum lub cev muaj zog. Los ntawm kev txheeb xyuas, nws tseem tuaj yeem pom tias lub cev muaj zog hlau poob yog lub ntsiab poob ntawm stator core tshwm sim los ntawm kev cuam tshuam ntawm kev ntxhov siab, rau lub cev muaj zog rotor, lub xeev khiav ntawm cov tub ntxhais hlau hauv lub xeev centrifugal tensile stress, tsis tsuas yog yuav tsis nce cov tub ntxhais poob, tab sis kuj yuav muaj qee yam kev txhim kho.

Qhov sib nqus susceptibility ntawm lub cev muaj zog core deteriorates nyob rau hauv cov xwm txheej ntawm hlau core kev nyuaj siab, thiab nws ncej inductance yuav raug txo mus rau ib tug tej yam kev mob. Tshwj xeeb, qhov sib nqus hluav taws xob ntawm lub tshuab hluav taws xob ruaj khov yog tshuaj xyuas. Cov ncej hlau nplaum sib nqus feem ntau suav nrog peb ntu: Qhov sib txawv ntawm huab cua, cov hlau nplaum ruaj khov thiab cov tub ntxhais rotor ruaj khov, uas cov hlau nplaum ruaj khov yog qhov tseem ceeb tshaj plaws. Vim li no, thaum lub magnetic susceptibility ntawm cov hlau nplaum ruaj khov lub cev muaj zog hloov pauv, cov ncej inductance tsis tuaj yeem hloov pauv zoo heev. Lub axial magnetic Circuit Court ntawm cov hlau nplaum ruaj khov lub cev muaj zog ntawm cov pa sib txawv thiab cov rotor core ruaj khov yog me dua li cov hlau nplaum ruaj khov. Thaum lub zog ntawm cov tub ntxhais hlau kev ntxhov siab tau txiav txim siab tag nrho, qhov sib nqus susceptibility deteriorates thiab cov ncej inductance txo qis. Kev cuam tshuam ntawm kev ntxhov siab ntawm cov khoom sib nqus ntawm cov hlau nplaum ruaj khov lub cev muaj zog raug tshuaj xyuas. Raws li cov khoom sib nqus ntawm cov tub ntxhais hlau ntawm lub cev muaj zog txo qis, qhov sib nqus sib nqus ntawm lub cev muaj zog txo, thiab lub tshuab hluav taws xob hluav taws xob ntawm lub tshuab hlau nplaum tas li kuj txo.
