Tshawb xyuas txog qhov sib txawv ntawm kev ua tau zoo ntawm cov hlau nplaum ntawm cov khoom siv hlau nplaum sib nqus thiab cov ntaub ntawv silicon steel
Zhao Guoxin thiab Kong Decai, soj ntsuam ntawm lub Tsev Kawm Ntawv ntawm Cov Hluav Taws Xob Engineering ntawm Shenyang University of Technology, tau sau nyob rau hauv phau ntawv Journal of Electrotechnical Engineering hauv xyoo 2018 uas cov khoom siv hlau nplaum sib txig sib txig ntawm cov hmoov hlau uas muaj cov nplais thiab muaj me me eddy tam sim no. Cov yam ntxwv ntawm tib-poj niam txiv neej tau ua ntawv thov nyob rau hauv xyoo tsis ntev los, tab sis lawv cov hysteresis poob loj thiab cov sib nqus permeability yog tsawg. Yog li no, daim ntawv thov thiab qhov sib txawv nrog qhov kev kawm ntawm silicon steel sheet xav tau kev tshawb nrhiav ntxiv.
Nyob rau hauv daim ntawv no, cov khoom sib nqus ntawm cov khoom sib nqus uas muaj hlau nplaum yog kuaj thawj zaug los ntawm cov qauv ntawm cov qauv, thiab cov ntaub ntawv tsis muaj qhov magnetization thiab cov ntaub ntawv ntawm cov zauv sib txawv. Tom qab ntawd, xwv kom sib piv thiab sojntsuam qhov sib txawv ntawm cov khoom siv hlau nplaum thiab cov ntaub ntawv silicon hlau nyob hauv daim ntawv thov kev siv tshuab, ob lub tshuab hluav taws xob sib txuas ntawm tus kheej tau tsim los siv cov khoom siv hlau nplaum sib nqus thiab silicon hlau raws feem, hlau poob thiab hlau ntawm ob cov ntaub ntawv raug soj ntsuam thiab xam. Txoj cai ntawm kev hloov ntawm ntau zaus. Thaum kawg, qhov txawv nruab nrab ntawm daim ntawv thov ntawm ob cov ntaub ntawv nyob rau hauv lub tshuab hluav taws xob txuas mus tas li mas tau los ntawm cov ntawv pov thawj, qhov tseeb ntawm qhov muab xam muaj tseeb, thiab daim ntawv thov ntau ntawm cov khoom siv hlau nplaum sib nqus tau muab sau ua ke.
SoftMagnetic Composite Materials (SMC) yog tau los ntawm cov hmoov hlau metallurgy tshuab ua ntej nws cov ntshav siab-purity hlau nrog insulating txheej thiab cov khoom siv organic. Nyob rau hauv xyoo tas los no, nws tau kawm ntau thiab tau siv rau hauv kev lag luam ntawm cov motors thiab lwm cov hauj lwm [1] -4]. Cov yam ntxwv ntawm SMC cov ntaub ntawv yuav ncaj qha tuaj molded thiab molded, uas ua rau cov qauv thiab electromagnetic tsim ntawm lub cev muaj zog dua thiab hloov tshiab. Nws qhib ib lub tswv yim tshiab rau daim ntawv thov thiab kev tsim ntawm lub cav thiab attracts ntau cov kws tshawb fawb [5-7].
SMC cov ntaub ntawv muaj cov resistivity thiab tsis tshua eddy tam sim no, ua SMC ntaub ntawv ntau haum rau siv hauv high-frequency motors, tab sis SMC cov ntaub ntawv kuj muaj qee qhov kev tsis pom los ntawm kev tsis pom zoo, xws li cov hlau tsis sib haum thiab qe loj loj. Yog li, cov cai tswjfwm kev cai thiab cov cwj pwm ntawm SMC cov ntaub ntawv nyob rau hauv cov kev lag luam tseem xav tau kev tshawb fawb ntxiv.
Hauv [7], SMC cov ntaub ntawv muaj peev xwm tau kawm tag nrho. Nws pom tau tias kev tsav tsheb ntawm SMC thiab silicon steel ntawv cov ntaub ntawv sib txawv ntawm kev sib txawv thiab sib txawv powers. Thaum lub cav raug tsim los ntawm 1000r / min thiab 625r / min, SMC Lub tshuab muaj zog muaj qhov tsis zoo. Thaum lub cav muaj zog 4A, qhov kev ua haujlwm yog 28% thiab 34.7% qis tshaj qhov ntawm lub cav hlau silicon. Thaum twg qhov voltage siab tshaj 1500r / feeb, SMC cov khoom siv zog dua, qhov no yog 3% siab tshaj qhov ntawm silicon steel sheet engine.
Ntaub ntawv [8] kuj piv cov txiaj ntsig ntawm kev siv lub tshuab xiam ntawm SMC cov ntaub ntawv thiab cov ntaub ntawv silicon steel. Nws tau pom tias qhov hluav taws xob tib cov hluav taws xob muaj hluav taws xob, SMC cov khoom siv zog yog 7% qis dua, tab sis SMC lub cev muaj zog ntau dua qhov hluav taws xob txaus hluav taws xob, tom qab txo hwj chim txaus, qhov ua tau nce yog 4.7%. Txawm li cas los xij, cov txiaj ntsim ntawm SMC lub cev qis dua qis dua ntawm lub silicon steel sheet motor. Thaum lub hwj huam ntawm qhov hluav taws xob yog 220V thiab 180V, nws yog 10.3% thiab 6.7% qis, feem.
Txawm hais tias SMC cov ntaub ntawv twb muaj qee yam kev tshawb nrhiav thiab daim ntawv thov, nws cov yeeb yam, lub sijhawm, cov cai thiab cov cwj pwm ntawm cov ntawv xov xwm silicon ntawm kev khiav hauj lwm ntau zaus tseem yuav tsum tau kawm.
Yuav kom kawm tau cov yam ntxwv ntawm SMC cov ntaub ntawv thiab txheeb xyuas qhov txawv ntawm lawv thiab cov cag ntoo uas yog cov tshuaj silicon, daim ntawv no ua ntej kuaj cov khoom sib nqus ntawm SMC cov ntaub ntawv ntawm Hoomas qauv Somaloy700, thiab sib piv lawv nrog feem ntau siv silicon steel sheet DW470 nrog cov tuab ntawm 0.5 hli. Ob tog hlau nplaum synchronous ntawm qhov loj thiab tsis tau tsim nrog SMC khoom thiab DW470 ua cov khoom siv tub ntxhais. Sib npaug ntawm qhov kev tshawb fawb thiab poob kev sib tw tau ua rau ntawm ob lub motors, thiab cov yam ntxwv thiab qhov txawv ntawm cov ntawv pov thawj uas tau ua los ntawm ob cov ntaub ntawv raug tshuaj xyuas. Thaum kawg, tus qauv tau qhia thiab Tests los ua kom pom qhov txawv ntawm kev ua tau zoo ntawm ob tsab prototypes.
Los ntawm kev ntsuam xyuas thiab kev sib piv ntawm daim ntawv no, cov yam ntxwv ntawm SMC cov ntaub ntawv tuaj yeem sau ua ke, thiab qhov sib txawv ntawm qhov kev sib tw ntawm SMC cov ntaub ntawv thiab cov ntaub ntawv silicon steel thiab daim ntawv thov ntawm SMC cov ntaub ntawv tuaj yeem muab tau cov cai rau daim ntawv thov ntawm SMC cov ntaub ntawv nyob hauv tshuab.

Yuav kom piv tau qhov sib txawv ntawm kev sib tw ntawm silicon steel sheet khoom thiab cov khoom siv hlau nplaum sib nqus hauv lub tshuab, ob lub qhov hluav taws xob synchronous nrog SMC khoom thiab DW470 raws li cov tub ntxhais tsim thiab tsim. Ua ke nrog lub caij kawg ntawm kev xam thiab kev tshawb nrhiav, cov ntsiab lus hauv qab no tau txais. nyob rau hauv xaus:
1) Cov khoom siv sib nqus ntawm cov khoom SMC tau raug kuaj raws li lub nplhaib qauv qauv. Cov curveization curves thiab poob curves ntawm cov ntaub ntawv SMC tau. Muab piv rau DW470, cov khoom siv hlau nplaum ntawm SMC cov ntaub ntawv tau pom muaj qis. Qhov nce ntxiv siab tshaj qhov poob. 400Hz yog qhov taw tes rau qhov tseem ceeb. Thaum twg tus zaus qis dua 400Hz, poob silicon steel ntawv cov ntaub ntawv me dua cov khoom ntawm SMC. Thaum twg tus zaus ntau tshaj 400Hz, qhov tshwj xeeb poob ntawm cov khoom siv hlau nplaum sib tov ntau dua DW470. khoom.
2) Raws li qhov tsis muaj kev sim, qhov rov qab electromotive quab yuam ntawm SMC tsab ntawv no me dua li ntawm DW470 lub cav, uas zoo ib yam nrog theoretical calculation, uas ua kom pom cov hlau tsis zoo ntawm SMC cov ntaub ntawv. Kev ntsuas ntawm ob daim qauv pom tau tias DW470 lub cev muaj zog ntawm lub cev muaj zog ntawm cov qis tshaj li ntawm 400 Hz, tiam sis raws li qhov muaj zog nce, qhov sib txawv ntawm cov khoom pov thawj ntawm cov khoom siv ob qho me me thiab me dua. Ntawm 400 Hz, ob qho tib si Feem ntau qhov sib npaug yog tib yam, uas yog raws li qhov kev ua theoretical. Nws qhia tau hais tias SMC tas li hlau nplaum synchronous lub cev muaj kev kawm zoo nyob rau nruab nrab thiab theem siab, uas muaj peev xwm offset cov shortcomings uas muaj hlau nplaum tsis zoo thiab hysteresis poob, thiab muaj zoo daim ntawv thov. .
3) Vim tias cov ntaub ntawv SMC tsis muaj zog, lub thickness yuav tsum muaj qhov tsim nyog thaum tsim, thiab qhov ntse ntse thiab cov ces kaum yuav tsum raug zam kom ntau li ntau tau. Tom qab ua tiav, nws yuav tsum tau coated nrog kua nplaum los yog epoxy resin kom lub zog ntawm tus ntxhais thiab tiv thaiv "slag".
