Qhov cuam tshuam ntawm laser txiav rau cov khoom sib nqus ntawm cov hlau tsis muaj hluav taws xob

GNEE Steel CRGO Hluav Taws Xob Silicon Steel

Nyob rau hauv lub ntsej muag ntawm lub ntiaj teb no lub zog ntsoog, lub zog efficiency ntawm cov khoom siv hluav taws xob tau dav kev txhawj xeeb. Kev txheeb cais qhia tias cov motors feem ntau suav txog li 2/3 ntawm kev siv hluav taws xob. Stator thiab rotor cores feem ntau yog ua los ntawm cov hlau tsis muaj hluav taws xob vim tias lawv muaj cov hlau nplaum zoo. Laser txiav yog dav siv nyob rau hauv kev ua cov hlau hluav taws xob, nrog rau qhov zoo ntawm kev tsis sib cuag, ceev txiav ceev thiab lwm yam. Txawm li cas los xij, ntau cov kev tshawb fawb tau pom tias qhov kev ntxhov siab tshwm sim los ntawm laser txiav ntawm cov hluav taws xob hlau phaj yuav cuam tshuam rau cov khoom sib nqus ntawm ntug, uas ua rau muaj kev nce hauv cov tub ntxhais poob, yog li kev txheeb xyuas cov degree thiab cov txheej txheem ntawm kev sib nqus degradation tom qab laser. txiav yog ib qho tseem ceeb los txhim kho cov khoom siv hluav taws xob zoo.

Txhawm rau txhawm rau kwv yees qhov tseeb ntawm qhov poob ntawm lub cev muaj zog, nws yog ib qho tseem ceeb heev uas yuav tsum tau txheeb xyuas qhov deterioration degree thiab cov txheej txheem ntawm cov hlau phaj uas tsis yog-oriented los ntawm laser txiav. Zhang Chang et al. los ntawm Hebei University of Technology suav thiab muab piv rau thaj tsam deterioration ntawmnon-oriented hluav taws xob steel phajtshwm sim los ntawm laser txiav los ntawm lub zos magnetic yam ntxwv kuaj system. Tom qab ntawd, raws li cov txheej txheem kev soj ntsuam sib nqus, cov qauv ntawm ntug kev sib txawv thiab nws txoj cai hloov pauv raws li kev sib nqus teb excitation.

Cov kws tshawb fawb tau ntsuas cov khoom sib nqus hauv zos ntawm unoriented steel 35WW250 ntawm qhov chaw sib txawv nyob rau hauv kev sib hloov sinusoidal excitation thiab ntsuam xyuas cov degree ntawm degradation raws li cov tub ntxhais poob los ntawm macroscopic foundations. Raws li kev hloov pauv ntawm hysteresis loops ua ntej thiab tom qab laser txiav, cov khoom sib nqus ntawm cov qauv ntug tau raug degraded los ntawm laser txiav, thiab ze rau qhov txiav ntug, qhov phem dua cov khoom sib nqus ntawm cov qauv. Cov khoom sib nqus ntawm thaj tsam li ntawm 18 hli ntawm ntug txo qis heev. Ntawm lawv, qhov tsis zoo ntawm cov khoom sib nqus yog qhov pom tseeb tshaj plaws hauv cheeb tsam tsawg dua 4 hli ntawm ntug.

Oriented hluav taws xob hlau

Los ntawm qhov pom ntawm cov tub ntxhais poob ntawm cov hlau tsis muaj kev taw qhia hluav taws xob ntawm cov zaus sib txawv thiab cov haujlwm, laser txiav ua rau muaj kev nce ntxiv hauv ntug poob, tshwj xeeb tshaj yog cov hysteresis poob thiab dynamic poob yog nce, thiab cov tub ntxhais poob yog qhov zoo. cuam ​​tshuam nrog kev ua haujlwm zaus. Qhov no yog vim hais tias hysteresis poob ntawm ferromagnetic cov ntaub ntawv los ntawm cov lus tsa suab ntawm magnetic domains, thiab cov txheej txheem laser txiav tsub kom qhov tsis kam ntawm magnetic domain motion, yog li ua rau hysteresis poob. Cov residual kev nyuaj siab tivthaiv perpendicular mus rau ntug kuj nce hysteresis poob. Qhov poob dynamic yog tsim los ntawm classical eddy tam sim no poob thiab ntau dhau los ntawm kev faib tsis sib xws ntawm cov qauv sib nqus sib nqus. Ib qho kev nce hauv qhov dav dav kuj tuaj yeem ua rau muaj kev nce ntxiv hauv kev poob.

Tsis tas li ntawd, cov kws tshawb fawb tau kawm txog qhov pom cov qauv sib nqus sib nqus ntawm ntug thiab cov txheej txheem evolution nyob rau hauv magnetic excitation los ntawm lub microscopic foundations. Cov txheej txheem laser txiav ua rau muaj kev hloov pauv tseem ceeb hauv cov qauv sib nqus ntawm cov chaw sib txawv. Magneto-optical kev soj ntsuam thiab hauv zos sib nqus ntsuas ntsuas qhov ua tau zoo ntawm txoj kev tshuaj ntsuam xyuas, uas yog qhov tseem ceeb rau kev ntsuam xyuas thiab kev txhim kho ntawm silicon steel ua technology.
