** Taw qhia
Thaum nws los txog rau cov tshuab thiab cov tshuab, muaj ntau yam sib txawv ntawm cov khoom uas tuaj rau hauv kev ua si. Ib qho piv txwv zoo li no yog qhov sib nqus rotor. Qhov no yog ib qho tseem ceeb ntawm ntau lub tshuab sib txawv, thiab nws muaj ntau yam zoo nkauj uas ua rau nws tsim nyog kawm txog. Hauv tsab xov xwm no, peb yuav ua qhov tob tob rau hauv lub ntiaj teb ntawm magnetic rotors, tshawb xyuas lawv yog dab tsi, lawv ua haujlwm li cas, thiab qhov twg lawv siv.
** Dab tsi yog magnetic rotor?
Nyob rau hauv nws cov theem pib tshaj, ib tug hlau nplaum rotor yog ib tug rotor uas muaj hlau nplaum. Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias tsis yog txhua tus rotors uas muaj cov hlau nplaum yog cov hlau nplaum sib nqus. Lub rotor sib nqus tshwj xeeb yog hais txog lub rotor uas siv kev sib cuam tshuam ntawm cov hlau nplaum thiab cov hlau nplaum sib nqus los tsim cov lus tsa suab.
Ib qho piv txwv ntawm cov hlau nplaum rotor yog lub rotor hauv lub tshuab hluav taws xob. Hauv qhov no, lub rotor muaj cov hlau nplaum uas tig ncig hauv lub stator uas muaj cov hlau nplaum. Raws li cov hlau nplaum hauv lub rotor cuam tshuam nrog cov hlau nplaum hauv lub stator, lawv tsim ib lub zog uas ua rau lub rotor tig.
** Sib nqus rotors ua haujlwm li cas?
Txhawm rau kom nkag siab tias cov rotors sib nqus ua haujlwm li cas, nws yog ib qho tseem ceeb kom nkag siab txog cov hauv paus ntawm cov hlau nplaum. Cov hlau nplaum muaj ob tug ncej: ib tug ncej qaum teb thiab ib tug ncej qab teb. Thaum ob lub hlau nplaum raug coj los ze ua ke, lawv cov ncej yuav nyiam los yog tawm tsam ib leeg, nyob ntawm seb lawv cov ncej zoo li cas los yog tawm tsam.
Nyob rau hauv ib tug sib nqus rotor, cov hlau nplaum yog teem nyob rau hauv ib txoj kev tshwj xeeb los tsim ib tug rotating magnetic teb. Raws li lub rotor spin, lub magnetic teb cuam tshuam nrog lub magnetic teb nyob rau hauv lub stator, tsim ib tug quab yuam uas ua rau lub rotor tig sai.
Muaj ob peb qhov sib txawv tsim rau cov hlau nplaum rotors, tab sis ib qho ntawm ib qho yog cov hlau nplaum ruaj khov rotor. Nyob rau hauv no tsim, lub rotor muaj cov hlau nplaum uas yog magnetized tas mus li. Cov hlau nplaum no cuam tshuam nrog cov hlau nplaum hauv lub stator los tsim kev txav.
Lwm tus tsim rau cov hlau nplaum rotors yog lub qhov txhab rotor. Nyob rau hauv no tsim, lub rotor muaj electromagnets es tsis txhob ntawm cov hlau nplaum mus tas li. Cov electromagnets txuas nrog lub zog sab nraud, thiab tam sim no khiav los ntawm lawv tsim ib qho chaw sib nqus uas cuam tshuam nrog cov hlau nplaum hauv stator.
** Cov rotors sib nqus siv nyob qhov twg?
Sib nqus rotors yog siv nyob rau hauv ntau yam ntawm cov cav tov thiab mechanisms. Ib qho kev siv ntau tshaj plaws yog nyob rau hauv hluav taws xob motors. Fais motors yog siv nyob rau hauv txhua yam ntawm tsheb mus rau cov khoom siv, thiab hlau nplaum rotors yog ib qho tseem ceeb ntawm cov motors.
Sib nqus rotors kuj tseem siv rau hauv cov tshuab hluav taws xob, uas yog cov tshuab uas hloov tshuab hluav taws xob rau hauv hluav taws xob hluav taws xob. Cov tshuab hluav taws xob ua haujlwm ntawm lub hauv paus ntsiab lus ntawm cov hluav taws xob hluav taws xob - tsis yog siv lub tshuab nqus hlau los tsim cov lus tsa suab, lawv siv cov lus tsa suab los tsim cov hlau nplaum. Lub rotor nyob rau hauv lub tshuab hluav taws xob muaj cov hlau nplaum uas tig ncig hauv lub stator uas muaj cov coils ntawm hlau. Raws li cov hlau nplaum tig, lawv tsim ib qho kev hloov magnetic teb uas induces ib tug tam sim no nyob rau hauv lub coils ntawm hlau.
Lwm daim ntawv thov ntawm magnetic rotors yog nyob rau hauv magnetic bearings. Sib nqus bearings siv kev sib xyaw ntawm cov hlau nplaum thiab cov khoom siv hluav taws xob kom levitate lub rotor, tshem tawm qhov xav tau ntawm cov kabmob ib txwm muaj. Qhov no tuaj yeem txo kev sib txhuam thiab ua kom muaj zog.
** Qhov zoo thiab qhov tsis zoo ntawm cov hlau nplaum rotors
Sib nqus rotors muaj ntau qhov zoo dua lwm hom rotors. Ib qho ntawm qhov zoo tshaj plaws yog tias lawv tuaj yeem ua haujlwm tau zoo. Vim tias tsis muaj kev sib cuag ntawm lub cev ntawm lub rotor thiab stator, muaj kev sib txhuam me me, uas txhais tau hais tias tsawg zog poob rau qhov cua sov. Qhov no tuaj yeem ua rau muaj kev ua haujlwm siab dua thiab txo cov nqi khiav haujlwm.
Lwm qhov zoo ntawm cov hlau nplaum rotors yog tias lawv tuaj yeem txhim khu kev qha. Vim tias tsis muaj lub cev bearings lossis txhuam uas tuaj yeem hnav, cov hlau nplaum sib nqus tuaj yeem muaj lub neej ntev dua li lwm hom rotors.
Txawm li cas los xij, kuj muaj qee qhov tsis zoo rau cov hlau nplaum rotors. Ib qho ntawm qhov tsis zoo tshaj plaws yog tias lawv tuaj yeem raug nqi ntau dua los tsim dua lwm hom rotors. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cov rotors uas siv cov khoom siv hluav taws xob, vim tias cov no xav tau lub zog sab nraud.
Lwm qhov tsis zoo ntawm cov hlau nplaum rotors yog tias lawv tuaj yeem ua ntau dua li lwm hom rotors. Qhov no txhais tau tias lawv tuaj yeem nyuaj rau kev tsim thiab tsim khoom, uas tuaj yeem ntxiv rau tus nqi.
** Lus xaus
Nyob rau hauv xaus, sib nqus rotors yog ib tug fascinating thiab tseem ceeb feem ntawm ntau yam sib txawv tshuab thiab mechanisms. Los ntawm hluav taws xob motors mus rau generators mus magnetic bearings, magnetic rotors muaj ntau yam kev siv. Thaum lawv muaj qee qhov tsis zoo, lawv kuj muaj ntau qhov zoo dua lwm hom rotors, suav nrog kev ua haujlwm siab thiab kev ntseeg siab. Raws li thev naus laus zis txuas ntxiv mus, nws yuav nthuav kom pom tias cov hlau nplaum sib nqus hloov zuj zus li cas thiab lawv siv li cas hauv txoj kev tshiab thiab tshiab.
