Lub Tsev Khoom Siv Hluav Taws Xob Hluav Taws Xob yog dab tsi thiab Yuav Ua Li Cas Txhim Kho Lub Cev Tsav Tsheb?
Lub tshuab hluav taws xob siv hluav taws xob hauv tsev yog ib qho tseem ceeb hauv cov motors uas tsav ntau yam khoom siv hauv tsev, los ntawm cov tshuab ntxhua khaub ncaws thiab lub tshuab nqus tsev mus rau chav ua noj blenders thiab cua txias. Cov hlau nplaum no feem ntau yog cov hlau nplaum ruaj khov ua los ntawm siab -kev ua tau zoo ferrite lossis tsis tshua muaj - cov ntaub ntawv hauv ntiaj teb, tsim los tsim cov hlau nplaum ruaj khov thiab muaj zog uas ua rau DC motors ua haujlwm tau zoo thiab ntseeg tau. Kev xaiv cov khoom siv hluav taws xob hauv tsev zoo yog qhov tseem ceeb, vim nws ncaj qha cuam tshuam rau lub cev muaj zog torque, lub zog ua haujlwm, suab nrov, thiab tag nrho cov cuab yeej siv tau ntev.
Cov khoom siv hluav taws xob hauv tsev hlau nplaum muaj ntau yam nyob ntawm cov khoom siv, cov duab, thiab daim ntawv thov. Feem ntau yog cov hlau nplaum ferrite, uas muab cov nqi zoo heev - kev ua tau zoo sib npaug thiab tau siv dav hauv cov khoom siv nrog kev ua haujlwm nruab nrab. Tsis tshua muaj- cov hlau nplaum hauv ntiaj teb, xws li cov hlau nplaum neodymium, muab cov hlau nplaum sib nqus ntau dua thiab qhov loj me, ua rau lawv zoo tagnrho rau cov khoom me me, siab-ceev motors siv hauv cov khoom siv niaj hnub compact. Segment hlau nplaum los yog arc- cov hlau nplaum zoo li feem ntau yog siv los ua kom haum cov rotors lub cev muaj zog, kom ntseeg tau tias qhov zoo tshaj plaws flux tis thiab lub cev muaj zog efficiency. Xaiv hom hlau nplaum raug thiab cov duab rau ib lub tshuab siv tshwj xeeb yog qhov tseem ceeb rau kev ua tiav kev ua haujlwm siab thiab kev ntseeg siab.
Piv rau lwm cov hlau nplaum, cov khoom siv hluav taws xob hauv tsev hlau nplaum tshwj xeeb yog tsim los tswj kev ua haujlwm tas mus li, cov khoom sib txawv, thiab qee zaus thermal stress. Txawm hais tias dav dav - cov hlau nplaum lub hom phiaj tuaj yeem poob flux lossis degrade sai dua nyob rau hauv kev caij tsheb kauj vab, siab - cov khoom siv hlau nplaum zoo tswj kev ua haujlwm ruaj khov thoob plaws lub cev muaj zog qhov kev cia siab. Kev tsim kho tshiab hauv kev tsim qauv siv lead ua, txheej thev naus laus zis, thiab qhov kub thiab txias- cov qauv tiv thaiv tau txhim kho cov kav ntev, txo qis kev pheej hmoo demagnetization, thiab txhim kho corrosion kuj, uas yog qhov tseem ceeb tshwj xeeb hauv cov khoom siv hauv tsev uas raug dej los yog cua sov.
Los ntawm kev xav hauv kev lag luam, tau muaj kev tsom mus rau cov khoom siv hlau nplaum ruaj khov thiab muaj txiaj ntsig zoo. Kev tsim kho tsis ntev los no hauv cov hlau nplaum ferrite koom nrog kev ua kom zoo ntawm cov nplej sib dhos thiab qhov ntom ntom kom txhim kho cov hlau nplaum sib nqus thaum txo cov khoom pov tseg. Ib yam li ntawd, cov tuam txhab tsim cov hlau nplaum neodymium tau nqis peev hauv cov tswv yim rov ua dua tshiab thiab txo qis - kev siv hauv ntiaj teb yam tsis muaj kev cuam tshuam rau kev ua haujlwm. Cov qauv no yog qhov tseem ceeb rau cov tuam txhab lag luam uas nrhiav ib puag ncig lub luag haujlwm cov saw hlau thiab tus nqi ruaj khov rau cov khoom tseem ceeb ntawm lub cev muaj zog. Kev paub txog cov xov xwm raw khoom, kev tsim kho thev naus laus zis, thiab cov kev cai tswj hwm yuav pab cov tuam txhab tswj hwm kev tsim khoom thiab txo cov nqi hloov pauv yam tsis tau xav txog.
Daim ntawv thov thiab kev teeb tsa cov khoom siv hauv tsev cov hlau nplaum yuav tsum tau ua tib zoo saib xyuas. Kev sib raug zoo ntawm cov hlau nplaum ntu nyob rau hauv lub rotor kom zoo ib yam sib nqus flux thiab pom lub cev muaj zog torque. Kev sib dhos feem ntau suav nrog muab cov hlau nplaum tso rau hauv cov rotor slots lossis siv cov nplaum nplaum rau cov ntu me me, ua raws li cov neeg kho tshuab los yog thermal curing los kho cov hlau nplaum kom ruaj ntseg. Kev tshuaj xyuas zoo suav nrog kev tshuaj xyuas qhov chaw hlau nplaum, lub zog adhesion, thiab sib nqus flux sib xws. Kev saib xyuas cov khoom siv lub cev muaj zog feem ntau tsis tas yuav hloov cov hlau nplaum nyob rau hauv ib txwm muaj, tab sis kev tshuaj xyuas ib ntus rau lub cev muaj zog, teeb meem kev coj tus kheej, lossis kev puas tsuaj ib puag ncig kom ntseeg tau tias cov hlau nplaum tseem ua haujlwm zoo.
Hauv kev xaus, cov khoom siv hluav taws xob hauv tsev muaj cov hlau nplaum ntau dua li cov khoom siv passive; lawv yog qhov tseem ceeb rau kev ua haujlwm ntawm lub cev muaj zog, kev ua haujlwm ntawm lub zog, thiab lub sijhawm ntev - kev ntseeg siab ntawm cov khoom siv hauv tsev. Los ntawm kev nkag siab ntau hom hlau nplaum, cov khoom siv, cov txheej txheem kev teeb tsa, thiab cov qauv kev lag luam, cov tuam ntxhab tuaj yeem txhim kho lub cev muaj zog, txo cov suab nrov ua haujlwm, thiab ua kom lub zog ua haujlwm. Xaiv qhov siab -zoo, zoo- cov hlau nplaum uas tsim nyog thiab ua raws li cov kauj ruam sib dhos ua kom ntseeg tau tias cov khoom siv hauv tsev ua haujlwm tau zoo, kav ntev dua, thiab ua tau raws li cov neeg siv khoom xav tau rau kev ua tau zoo thiab kav ntev.
