Generator vs Alternator
Kev txhais dav dav, lub tshuab hluav taws xob yog lub ntsiab lus dav dav rau cov khoom siv uas hloov cov tshuab hluav taws xob rau hluav taws xob, thiab lub tshuab hluav taws xob yog ib hom tshuab hluav taws xob uas tsim hluav taws xob hloov pauv.
Ntau txog Hluav Taws Xob Hluav Taws Xob
Lub hauv paus ntsiab lus tom qab kev ua haujlwm ntawm ib lub tshuab hluav taws xob yog Faraday txoj cai ntawm electromagnetic induction. Lub tswv yim hais los ntawm lub hauv paus ntsiab lus no yog tias, thaum muaj kev hloov ntawm magnetic teb nyob rau hauv ib tug neeg xyuas pib (piv txwv li, ib tug hlau), electrons raug yuam kom txav mus rau hauv ib qho kev taw qhia perpendicular mus rau cov kev taw qhia ntawm lub magnetic teb. Qhov no tshwm sim hauv kev tsim lub siab ntawm electrons nyob rau hauv tus neeg xyuas pib (electromotive force), uas ua rau muaj kev khiav ntawm electrons nyob rau hauv ib qho kev taw qhia.
Yuav kom muaj kev tshaj lij, lub sijhawm hloov pauv ntawm cov hlau nplaum sib nqus thoob plaws tus neeg xyuas pib ua rau lub zog hluav taws xob hauv tus neeg xyuas pib, thiab nws cov kev taw qhia yog muab los ntawm Fleming txoj cai sab xis. Qhov tshwm sim no yog siv ntau los tsim hluav taws xob.
Txhawm rau ua tiav qhov kev hloov pauv hauv cov hlau nplaum sib nqus hla cov hlau nplaum, cov hlau nplaum thiab cov xaim xaim raug hloov mus, xws li cov flux sib txawv raws li txoj haujlwm. Los ntawm kev nce tus naj npawb ntawm cov xov hlau, koj tuaj yeem ua kom lub zog ntawm electromotive; yog li ntawd cov xov hlau raug mob rau hauv ib lub kauj, uas muaj ntau txoj kev tig. Kev teeb tsa lub teb sib nqus los yog lub kauj hauv kev sib hloov, thaum lwm qhov yog nyob ruaj khov tso cai rau kev hloov pauv hloov pauv mus tas li.
Ib feem ntawm lub tshuab hluav taws xob yog hu ua Rotor, thiab qhov chaw nres tsheb yog hu ua stator. Lub emf generating ib feem ntawm lub tshuab hluav taws xob yog hu ua Armature, thaum lub magnetic teb tsuas yog hu ua Field. Armature tuaj yeem siv los ua tus stator lossis rotor, thaum lub teb tivthaiv yog lwm qhov.
Kev ua kom lub zog ua haujlwm ntxiv kuj tso cai rau kev ua kom muaj zog emf. Txij li cov hlau nplaum ruaj khov tsis tuaj yeem muab qhov kev siv zog uas xav tau los txhim kho lub zog tsim hluav taws xob los ntawm lub tshuab hluav taws xob, electromagnets tau siv. Ib qho qis dua tam sim no ntws los ntawm lub teb chaws no tshaj li lub armature Circuit Court thiab qis dua tam sim no dhau los ntawm cov hlua khi, uas ua rau cov hluav taws xob sib txuas hauv lub rotator. Raws li qhov tshwm sim, feem ntau ntawm AC generators muaj lub teb winding ntawm lub rotor thiab stator raws li armature winding.
Ntau txog Alternator
Alternators ua haujlwm ntawm tib lub hauv paus ntsiab lus raws li lub tshuab hluav taws xob, siv lub rotor winding raws li thaj chaw tivthaiv thiab armature winding raws li stator. Qhov sib txawv tsis muaj kev hloov pauv hauv polarizations ntawm windings yog xav tau; Yog li ntawd, kev sib cuag rau lub windings tsis yog muab los ntawm ib tug commutator, raws li nyob rau hauv ib tug DC generator, tab sis ncaj qha kev cob cog rua. Feem ntau cov alternators siv peb stator windings li no cov zis alternator yog peb theem tam sim no. Cov zis tam sim no raug kho los ntawm tus choj rectifiers.
Qhov tam sim no rau lub rotor winding tuaj yeem tswj tau; Raws li qhov tshwm sim, qhov tso zis hluav taws xob ntawm lub tshuab hluav taws xob tuaj yeem tswj tau.
Kev siv ntau tshaj plaws ntawm cov alternators yog nyob rau hauv tsheb, qhov twg lub zog ntawm lub cav muab rau lub rotor ncej (los ntawm lub crankshaft) hloov mus rau lub zog hluav taws xob, thiab ces siv rau recharge lub accumulator roj teeb nyob rau hauv lub tsheb.
Generator vs Alternator
• Lub tshuab hluav taws xob yog cov khoom siv dav dav, thaum lub tshuab hluav taws xob yog hom tshuab hluav taws xob tsim hluav taws xob AC tam sim no.
• Alternators siv voltage regulators thiab rectifiers los tsim ib tug DC tso zis, thaum nyob rau hauv lwm yam generators DC tam sim no tau los ntawm kev ntxiv ib tug commutator los yog AC tam sim no yog tsim.
• Cov khoom siv hluav taws xob tuaj yeem muaj qhov sib txawv vim qhov hloov pauv ntawm rotor zaus (tab sis nws tsis muaj txiaj ntsig vim tias tam sim no raug kho rau DC), thaum lwm lub tshuab hluav taws xob ua haujlwm rau qhov zaus ntawm lub rotor ncej.
• Alternators yog siv hauv tsheb, los tsim hluav taws xob hluav taws xob.
