Dc lub cev muaj zog tsav hom.Dc tsav raws li txoj kev tsav pheej yig tau ntev tau siv dav hauv cov khoom siv hluav taws xob.Dc system nws tus kheej muaj qee qhov tsis xws luag hauv kev ua haujlwm, kev saib xyuas thiab lwm yam.Cov tsheb fais fab ua ntej xyoo 1990 tau yuav luag tag nrho los ntawm dc motors.Dc lub cev muaj zog nws tus kheej muaj kev ua haujlwm tsawg, ntim loj thiab loj, commutator thiab carbon txhuam txwv kev txhim kho ntawm nws qhov ceev, kev kub ceev ntawm 6000 ~ 8000r / min.
Lub tshuab hluav taws xob yog tsim los ntawm qhov tshwm sim ntawm lub zog coil rotating los ntawm kev quab yuam hauv qhov chaw sib nqus.Piv nrog rau DC lub cev muaj zog, AC lub cev muaj zog ntawm forklift muaj kev ua haujlwm zoo heev.Cov tuam txhab forklift hauv qab no piav qhia cov yam ntxwv ntawm AC lub cev muaj zog thiab DC lub cev muaj zog.Lub AC lub cev muaj zog feem ntau yog siv los ntawm electromagnet winding los yog faib stator winding rau tsim ib qho chaw sib nqus thiab tig armature lossis rotor.Tsis muaj plua plav tsim tom qab siv cov pa roj carbon txhuam, huv si hauv ib puag ncig, txhim kho lub neej kev pab cuam ntawm lub cev muaj zog.Ac lub cev muaj zog ua hauj lwm efficiency siab dua, thiab tsis muaj pa taws, tsis hnov tsw, tsis txhob ua phem rau ib puag ncig, suab nrov me me.Vim muaj cov txiaj ntsig zoo, nws tau siv dav hauv kev lag luam thiab kev ua liaj ua teb, kev thauj mus los, kev tiv thaiv hauv tebchaws, kev lag luam thiab khoom siv hauv tsev, khoom siv kho mob thiab lwm yam.
Induction lub cev muaj zog AC tsav system yog ib lub tshuab tshiab tsim nyob rau hauv 1990′s.Qhov zoo tshaj plaws ntawm ac motors yog tias lawv tsis muaj cov txhuam hniav, thiab lawv tsis muaj cov kev txwv siab tam sim no uas dc motors feem ntau muaj, uas txhais tau hais tias hauv kev xyaum lawv tuaj yeem tau txais ntau lub zog thiab ntau dua braking torque, yog li lawv tuaj yeem khiav ceev dua.Cov cua sov ntawm AC lub cev muaj zog feem ntau tshwm sim hauv stator coil ntawm lub plhaub lub cev muaj zog, uas yooj yim rau kev ua kom txias thiab txias.Yog li ntawd, AC motors yuav tsum muaj tsawg dua cov khoom siv DC motors, tsis muaj qhov hnav uas yuav tsum tau hloov tsis tu ncua, yuav luag tsis muaj kev saib xyuas, ua haujlwm zoo dua, ruaj khov dua.
Dc lub cev muaj zog yog lub cev muaj zog uas hloov cov hluav taws xob tam sim no mus rau hauv lub tshuab hluav taws xob.Vim nws txoj kev tswj hwm kev ua tau zoo, nws tau siv dav hauv kev tsav tsheb hluav taws xob.DC lub cev muaj zog raws li hom excitation tau muab faib ua cov hlau nplaum ruaj khov, lwm yam zoo siab thiab nws tus kheej zoo siab peb pawg.Cov pa roj carbon txhuam hnav ua cov plua plav, uas cuam tshuam ncaj qha rau kev pabcuam lub neej ntawm lub cev muaj zog.Lub cev muaj zog tsis muaj cov qauv tsim, cov cua sov tsim tawm hauv lub cev muaj zog thaum ua haujlwm, cov cua sov dissipation tsis muaj zog, tsis zoo rau lub cev muaj zog rau lub sijhawm ntev.Lub zog backflush efficiency ntawm braking yog tsawg dua 15%.Dc lub cev muaj zog muaj cov qauv tsim thiab cov nqi tsim khoom siab;Kev tu cov teeb meem, thiab dc fais fab mov, cov nqi kho mob siab.Feem ntau siv rau kev pib hauv qhov hnyav lossis xav tau kev hloov kho ntawm cov tshuab ceev, xws li loj reversible dov zeb, winch, hluav taws xob locomotive, trolley, thiab lwm yam, yog tsav los ntawm dc lub cev muaj zog.
Nyob rau hauv xyoo tas los no, nrog kev nce qib ntawm ac induction lub cev muaj zog sib txawv zaus thev naus laus zis, thiab lub zog hluav taws xob semiconductor thiab microprocessor ceev, txhim kho ac induction lub cev muaj zog tsav system piv nrog dc lub cev muaj zog tsav, nrog kev ua haujlwm siab, ntim me me, tsis zoo, qauv yooj yim, txij nkawm dawb, yooj yim rau txias thiab qhov zoo ntawm kev pab lub neej ntev.Qhov ceev ntawm lub kaw lus yog qhov dav, thiab nws tuaj yeem paub qhov tsis tshua muaj zog torque thiab kev kub ceev tsis tu ncua lub zog ua haujlwm, uas tuaj yeem ua tau raws li cov yam ntxwv ceev uas xav tau los ntawm kev tsav tsheb fais fab.Nws tuaj yeem hais tias nws yog qhov ua ntej sai ntawm cov tshuab semiconductor uas tau yug los rau kev hloov kho thev naus laus zis ntawm AC lub cev muaj zog thiab ua kom muaj peev xwm tswj tau ntawm AC lub cev muaj zog.Ntxiv mus, nrog kev poob qis ntawm tus nqi ntawm cov khoom siv hluav taws xob tsis tu ncua, tus nqi ntawm ac motor controller hardware tuaj yeem txo qis, yog li tso lub hauv paus rau kev nce qib loj thiab kev siv ntawm AC tsav system, tsim cov xwm txheej.
