Txoj kev loj hlob ntawm cov hlau nplaum ruaj khov motors yog ze rau kev tsim cov khoom siv hlau nplaum ruaj khov.kuv lub teb chaws yog thawj lub teb chaws nyob hauv lub ntiaj teb no nrhiav tau cov khoom sib nqus ntawm cov khoom siv hlau nplaum ruaj khov thiab siv rau kev xyaum.Ntau tshaj li ob txhiab xyoo dhau los, peb lub teb chaws tau siv cov khoom sib nqus ntawm cov khoom siv hlau nplaum ruaj khov los ua ib lub tshuab raj, uas tau ua lub luag haujlwm loj hauv kev tsav tsheb, kev ua tub rog thiab lwm yam.Nws tau dhau los ua ib qho ntawm plaub qhov kev tsim khoom zoo tshaj plaws hauv kuv lub tebchaws thaum ub.

Kev ceev faj rau cov hlau nplaum ruaj khov

1. Sib nqus Circuit Court qauv thiab tsim kev suav

Txhawm rau muab kev ua si tag nrho rau cov khoom sib nqus ntawm ntau yam khoom siv hlau nplaum ruaj khov, tshwj xeeb tshaj yog cov khoom sib nqus zoo heev ntawm cov hlau nplaum tsis tshua muaj hauv ntiaj teb, thiab tsim cov khoom siv hluav taws xob ruaj khov, cov qauv thiab cov qauv tsim cov qauv ntawm cov hlau nplaum ib txwm muaj. hluav taws xob excitation motors tsis tuaj yeem siv tau yooj yim., yuav tsum tau tsim lub tswv yim tshiab tsim, thiab cov qauv sib nqus hluav taws xob yuav tsum tau rov txheeb xyuas thiab txhim kho.Nrog rau txoj kev loj hlob sai ntawm cov cuab yeej siv computer thiab software technology, nrog rau kev txhim kho txuas ntxiv ntawm cov qauv tsim niaj hnub xws li electromagnetic teb cov lej suav, kev tsim kho kom zoo thiab simulation thev naus laus zis, los ntawm kev sib koom ua ke ntawm lub cev muaj zog academia thiab engineering zej zog, nws tau dav dav. siv nyob rau hauv lub tswv yim tsim, Breakthrough kev vam meej tau ua nyob rau hauv kev suav cov txheej txheem, structural technology thiab tswj technology, thiab lwm yam., thiab ib tug txheej ntawm kev tsom xam thiab kev tshawb fawb txoj kev thiab computer-pab tsom xam thiab tsim software combining electromagnetic teb cov lej suav thiab sib npaug sib nqus Circuit Court analytical kev daws teeb meem tau tsim, thiab txhim kho tas li..

2. Tswj teeb meem

Lub cev muaj zog hlau nplaum ruaj khov tuaj yeem tswj hwm nws qhov chaw sib nqus yam tsis muaj lub zog sab nraud, tab sis nws kuj ua rau nws nyuaj heev los kho thiab tswj nws cov hlau nplaum sab nraud.Nws yog ib qho nyuaj rau lub tshuab hluav taws xob hlau nplaum ruaj khov los kho nws cov zis hluav taws xob thiab lub zog hluav taws xob los ntawm sab nraud, thiab cov hlau nplaum ruaj khov DC lub cev tsis tuaj yeem kho nws qhov ceev los ntawm kev hloov txoj kev excitation.Cov no txwv qhov kev thov ntau yam ntawm cov hlau nplaum ruaj khov motors.Txawm li cas los xij, nrog kev txhim kho sai ntawm cov khoom siv hluav taws xob hluav taws xob thiab kev tswj cov thev naus laus zis xws li MOSFETs thiab IGBTs, cov hlau nplaum feem ntau tuaj yeem siv tau yam tsis muaj kev tswj xyuas qhov sib nqus thiab tsuas yog nrog kev tswj hwm armature.Thaum tsim, nws yog ib qho tsim nyog los ua ke peb cov thev naus laus zis tshiab ntawm cov khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb, cov khoom siv hluav taws xob hluav taws xob thiab microcomputer tswj, kom lub zog hlau nplaum ruaj khov tuaj yeem khiav hauv cov haujlwm tshiab.

3. Qhov teeb meem ntawm irreversible demagnetization

Yog tias qhov tsim lossis siv tsis raug, lub tshuab hlau nplaum ruaj khov yuav nyob rau hauv qhov kev txiav txim ntawm armature cov tshuaj tiv thaiv los ntawm qhov inrush tam sim no thaum kub siab dhau (NdFeB ruaj khov hlau nplaum) lossis qis dhau (ferrite ruaj khov hlau nplaum), lossis thaum muaj Cov neeg kho tshuab kev vibration hnyav Nws muaj peev xwm ua rau irreversible demagnetization, los yog poob ntawm magnetization, uas yuav txo tau cov kev ua tau zoo ntawm lub cev muaj zog thiab txawm ua rau nws unusable.Yog li ntawd, nws yog ib qho tsim nyog los tshawb nrhiav thiab tsim cov txheej txheem thiab cov cuab yeej siv los kuaj xyuas qhov thermal stability ntawm cov khoom siv hlau nplaum ruaj khov tsim nyog rau cov tuam txhab tsim hluav taws xob, thiab txhawm rau txheeb xyuas qhov muaj peev xwm los tiv thaiv demagnetization ntawm ntau yam qauv, thiaj li ua raws li kev ntsuas kom ntseeg tau tias thaum lub sij hawm tsim. thiab tsim khoom.Cov hlau nplaum tas mus li tsis poob lawv cov hlau nplaum.

4. Cov teeb meem nqi

Ferrite mus tas li hlau nplaum motors, tshwj xeeb tshaj yog me me mus tas li hlau nplaum DC motors, tau siv dav vim lawv cov qauv yooj yim thiab cov txheej txheem, txo qhov hnyav, thiab feem ntau qis dua tus nqi hluav taws xob excitation motors.Txij li thaum lub ntiaj teb tsis tshua muaj cov hlau nplaum ruaj khov tseem kim heev tam sim no, tus nqi ntawm lub ntiaj teb tsis tshua muaj cov hlau nplaum ruaj khov motors feem ntau siab dua li cov hluav taws xob excitation motors, uas yuav tsum tau them nyiaj los ntawm nws cov kev ua haujlwm siab thiab kev ua haujlwm txuag nyiaj.Qee lub sij hawm, xws li lub suab coil motors ntawm lub computer disk drives, qhov kev ua tau zoo ntawm NdFeB cov hlau nplaum ruaj khov yog txhim kho, qhov ntim thiab qhov hnyav tau txo qis, thiab tag nrho cov nqi raug txo.Hauv kev tsim qauv, nws yog ib qho tsim nyog los sib piv qhov kev ua tau zoo thiab tus nqi raws li cov sijhawm siv tshwj xeeb thiab cov kev xav tau los txiav txim siab qhov kev xaiv, tab sis kuj tseem yuav tsim kho cov txheej txheem tsim thiab tsim kom zoo kom txo tau tus nqi.
