Txij li cov tub ntxhais lub cev muaj zog feem ntau cuam tshuam los ntawm ntau yam ntawm lub cev xws li magnetic teb, qhov kub thiab txias, qhov kev ntxhov siab, thiab zaus thaum ua haujlwm; Nyob rau tib lub sijhawm, cov txheej txheem sib txawv xws li cov kev ntxhov siab seem uas tsim los ntawm cov ntawv stamping thiab shearing ntawm silicon steel los xij, qhov kev ncua deb ntawm lub plhaub thiab lub stator core Lub compressive kev ntxhov siab tsim los ntawm lub tes tsho thaum tshav kub kub, lub centrifugal nro generated los ntawm kev ua haujlwm siab. ntawm lub rotor, thiab gradient kub generated los ntawm qhov kub nce tus yam ntxwv yuav cuam tshuam tag nrho cov kev ua tau zoo ntawm cov tub ntxhais. Cov yam tseem ceeb no yuav ua rau cov hlau poob ntawm lub cev muaj zog yuav siab dua li tus nqi ib txwm muaj thiab ua rau tsis muaj qhov tsis zoo.
Cov txiaj ntsig ntawm kev tshawb fawb hauv tsev thiab txawv teb chaws qhia tau hais tias: cov tub ntxhais hlau ntawm lub cev muaj zog feem ntau ua haujlwm ntawm qhov kub thiab txias, cov hlau tsis zoo ntawm silicon steel daim ntawv txo qis nrog qhov nce ntawm qhov kub thiab txias, thaum cov hlau poob ntawm 6.5% siab silicon steel nce ntxiv nrog rau qhov kub thiab txias. nce kub. Rau cov motors ntsia nrog kev cuam tshuam haum rau hauv rooj plaub, rooj plaub yuav ua rau muaj kev ntxhov siab loj ntawm cov tub ntxhais hlau, thiab cov tub ntxhais hlau lub cev muaj zog yuav ua rau muaj kev ntxhov siab txog li 10Mpa-150Mpa thaum lub sijhawm ua haujlwm, thiab qhov thaiv hom hlau tseem ceeb yog qhov tsim nyog rau loj ntau lawm, uas yog feem ntau Ib tug shrink haum los yog compression txheej txheem yuav tsum tau kho cov tub ntxhais, thiab cov hlau poob ntawm lub cev muaj zog nrog shrink haum los yog nias haum tsub kom ho piv rau lub unstressed rooj plaub. Cov ntsiab lus ntawm silicon ntawm 6.5% siab silicon steel yog ntau dua li cov tsoos silicon steel, yog li cov hlau poob ntawm 6.5% siab silicon steel yog qis dua vim qhov nce ntawm compressive kev nyuaj siab, thaum cov hlau poob ntawm cov tsoos silicon steel yog siab dua. kom nce compressive kev nyuaj siab. Lub deterioration ntawm hlau poob los ntawm compressive kev nyuaj siab yog txwv, thiab thaum cov kev nyuaj siab mus txog ib tug tej yam nqi, lub deterioration ntawm hlau poob yog tsis pom tseeb.
Ma Deji, tus kws tshawb fawb ntawm Shenyang University of Technology, tau sim cov khoom sib nqus ntawm 6.5% high-silicon steel nyob rau hauv cov xwm txheej ntawm compressive kev nyuaj siab thiab kub sib txuas, thiab kho cov hlau poob qauv, thiab piv 6.5% high-silicon steel nrog cov tsoos silicon. hlau. Los ntawm kev xaav ntawm cov ntaub ntawv, qhov zoo ntawm 6.5% siab silicon steel yog soj ntsuam. Thiab pub rov qab rau lub cev muaj zog ua kom nws qhov kev ua tau zoo dua qub.
Los ntawm kev tshawb fawb ntawm cov hlau poob ntawm 6.5% Si nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, cov kws tshawb fawb pom tias: thaum kub thiab compressive kev nyuaj siab ua rau cov khoom nce, piv nrog rau lwm cov tsoos silicon steels, poob deterioration ntawm 6.5% Si. me me heev; 6.5% high-silicon steel muaj tsawg hlau poob deterioration nyob rau hauv multi-physics coupling tej yam kev mob vim muaj kev ntxhov siab nyob rau hauv, me me hysteresis coefficient thiab loj grain loj; thaum 6.5% high-silicon steel yog siv los ua lub cev muaj zog stator core, lub casing txais yuav shrink haum Nruab nyob rau hauv tib txoj kev, yuav muaj ib tug me me hlau poob.
