Nyob ntawm seb hom kev kaw lus tau tsim thiab qhov chaw nyob hauv qhov chaw uas nws ua haujlwm, lub cev muaj zog hnyav tuaj yeem yog qhov tseem ceeb heev rau tag nrho cov nqi thiab cov nqi khiav haujlwm ntawm lub cev.Kev txo lub cev muaj zog tuaj yeem hais nyob rau hauv ntau cov lus qhia, suav nrog kev tsim lub cev muaj zog thoob ntiaj teb, kev tsim khoom zoo, thiab kev xaiv cov khoom siv.Txhawm rau ua tiav qhov no, nws yog qhov tsim nyog los txhim kho txhua yam ntawm kev txhim kho lub cev muaj zog: los ntawm kev tsim kom muaj txiaj ntsig zoo ntawm cov khoom siv cov khoom siv tau zoo, kev siv cov khoom siv hnyav thiab cov txheej txheem tsim tshiab.Feem ntau hais lus, kev ua haujlwm ntawm lub cev muaj zog nyob ntawm hom, qhov loj me, kev siv lub cev muaj zog, thiab tseem nyob ntawm qhov zoo thiab qhov ntau ntawm cov khoom siv.Yog li ntawd, los ntawm tag nrho cov no, hluav taws xob motors yuav tsum tau tsim los ntawm kev siv lub zog thiab cov nqi tsim nyog.
Lub cev muaj zog yog ib qho khoom siv hluav taws xob hloov hluav taws xob uas hloov hluav taws xob hluav taws xob mus rau hauv lub tshuab hluav taws xob hauv daim ntawv ntawm cov kab los yog cov lus teb. Lub hauv paus ntsiab lus ua haujlwm ntawm lub cev muaj zog feem ntau yog nyob ntawm kev sib cuam tshuam ntawm cov hlau nplaum thiab hluav taws xob.Ntau yam tsis tuaj yeem siv los sib piv cov motors: torque, lub zog ceev, kev tsim kho, kev khiav hauj lwm hauv paus ntsiab lus, tsis zoo, cov lus teb dynamic thiab efficiency, qhov kawg yog qhov tseem ceeb tshaj plaws.Cov laj thawj rau kev ua haujlwm tsis zoo ntawm lub cev muaj zog tuaj yeem raug ntaus nqi los ntawm cov hauv qab no: qhov loj me, tsis tshua muaj hluav taws xob ua haujlwm ntawm lub cev muaj zog siv, kev siv tshuab tsis zoo ntawm cov neeg siv kawg (twj, kiv cua, compressors, thiab lwm yam.) Tsis muaj kev tswj ceev uas tsis zoo. khaws cia los yog tsis muaj nyob.
Txhawm rau kom ua tiav lub zog ua haujlwm ntawm lub cev muaj zog, kev poob los ntawm ntau lub zog hloov pauv thaum lub sijhawm ua haujlwm ntawm lub cev yuav tsum raug txo kom tsawg.Qhov tseeb, nyob rau hauv lub tshuab hluav taws xob, lub zog yog hloov los ntawm hluav taws xob mus rau electromagnetic thiab rov qab mus rau txhua yam.Efficiency-enhancing electric motors txawv ntawm cov pa hluav taws xob motors vim tias lawv muaj qhov poob tsawg.Qhov tseeb, nyob rau hauv cov pa motors, kev poob yog feem ntau yog tshwm sim los ntawm: kev sib txhuam losses thiab mechanical losses vim windage losses (bearings, txhuam thiab qhov cua) losses nyob rau hauv lub tshuab nqus tsev hlau (feem ntau rau lub square ntawm voltage), muaj feem xyuam rau cov kev hloov nyob rau hauv flow direction Losses vim mus rau hysteresis ntawm lub zog dispersed ntawm cov tub ntxhais, thiab poob vim Joule nyhuv (feem ntau rau lub square ntawm tam sim no) vim eddy tam sim no los ntawm circulating currents thiab flow variations nyob rau hauv lub tub ntxhais.
tsim nyog
Kev tsim lub cev muaj zog tshaj plaws yog qhov tseem ceeb ntawm kev txo qhov hnyav, thiab vim tias feem ntau lub cev muaj zog yog tsim los rau kev siv dav, lub cev muaj zog rau ib daim ntawv thov tshwj xeeb feem ntau loj dua qhov xav tau tiag tiag.Yuav kom kov yeej qhov kev sib tw no, nws yog ib qho tseem ceeb kom nrhiav tau cov tuam txhab tsim khoom lag luam uas txaus siab los hloov cov kev cai ib nrab, los ntawm lub cev muaj zog windings thiab magnetics rau thav duab loj.Txhawm rau kom ntseeg tau tias muaj qhov tseeb winding, nws yog ib qho tsim nyog yuav tsum paub cov kev qhia tshwj xeeb ntawm lub cev muaj zog kom lub zog meej thiab nrawm uas yuav tsum tau ua rau daim ntawv thov tuaj yeem tswj tau.Ntxiv nrog rau kev kho cov windings, manufacturers kuj tseem tuaj yeem hloov qhov sib nqus tsim ntawm lub cev muaj zog raws li kev hloov pauv hauv permeability. Kev tso cai ntawm cov hlau nplaum tsis tshua muaj hauv ntiaj teb ntawm lub rotor thiab stator tuaj yeem pab ua kom lub cev muaj zog tag nrho.
kev tsim khoom tshiab
Cov neeg tsim khoom muaj peev xwm txuas ntxiv txhim kho lawv cov khoom siv los tsim cov khoom siv lub cev muaj zog siab dua, tshem tawm cov phab ntsa tuab thiab qhov chaw ntom ntom ib zaug siv los ua qhov kev nyab xeeb ntawm kev tawg.Vim hais tias txhua qhov kev tsim kho dua tshiab thiab tsim los siv cov thev naus laus zis tshiab, qhov hnyav tuaj yeem raug txo nyob rau hauv ntau qhov chaw uas suav nrog cov khoom sib nqus, xws li rwb thaiv tsev thiab txheej txheej, thav duab thiab lub cev muaj zog.
xaiv cov khoom siv
Kev xaiv cov khoom muaj feem cuam tshuam rau kev ua haujlwm ntawm lub cev muaj zog, kev ua haujlwm thiab qhov hnyav, uas yog qhov pom tseeb tshaj plaws piv txwv ntawm vim li cas thiaj li muaj ntau lub tuam txhab siv aluminium thav duab es tsis txhob stainless hlau.Cov neeg tsim khoom tau txuas ntxiv mus sim cov ntaub ntawv nrog cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab cov tuam txhab tsim khoom siv ntau yam khoom sib txawv nrog rau cov hlau sib zog uas muaj kev sib tw rau cov khoom siv hlau.Rau lub hom phiaj ntawm kev txhim kho, muaj ntau yam khoom siv ntxiv dag zog, polymers thiab resins, nyob ntawm tus neeg siv cov kev cai tshwj xeeb rau lub cev muaj zog kawg.Raws li cov kws tsim lub cev muaj zog txuas ntxiv mus sim thiab tshawb fawb lwm yam khoom siv, suav nrog cov txheej txheem qis thiab cov resins rau lub hom phiaj sib khi, lawv nqus lub neej tshiab rau hauv cov txheej txheem tsim khoom, uas feem ntau cuam tshuam qhov hnyav ntawm lub cev muaj zog.Tsis tas li ntawd, cov chaw tsim khoom muab cov motors tsis muaj zog, uas tuaj yeem cuam tshuam rau lub cev hnyav los ntawm kev tshem tawm cov ncej tag.
nyob rau hauv xaus
Cov thev naus laus zis uas siv cov khoom siv hnyav, cov txheej txheem tsim tshiab, thiab cov khoom sib nqus kom txo lub cev hnyav thiab txhim kho lub cev muaj zog.Fais motors, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov tsheb, sawv cev ib tug zuj zus rau yav tom ntej technologies.Yog li, txawm tias tseem muaj txoj hauv kev mus ntev, cia siab tias qhov no yuav dhau los ua ib qho kev sib koom ua ke ntawm kev siv tshuab, nrog kev txhim kho kev siv hluav taws xob zoo los daws cov teeb meem ntsig txog kev txuag hluav taws xob.
