Dab tsi yog qhov txawv ntawm AC lub cev muaj zog thiab DC lub cev muaj zog?

Raws li cov cuab yeej tseem ceeb rau kev hloov hluav taws xob rau hauv lub zog siv tshuab, cov motors tau siv dav hauv ntau yam kev lag luam thiab pej xeem. Raws li kev ua haujlwm sib txawv, lub cev muaj zog tuaj yeem muab faib ua ob pawg: AC motors thiab DC motors. Muaj qhov sib txawv tseem ceeb ntawm AC motors thiab DC motors nyob rau hauv cov nqe lus ntawm kev ua hauj lwm, cov qauv, thiab kev siv scenarios.

1, Txoj cai ua haujlwm
AC lub cev muaj zog: AC lub cev muaj zog yog ib hom ntawm lub cev muaj zog raws li lub hauv paus ntsiab lus ntawm electromagnetic induction. Nws lub hauv paus ntsiab lus ua haujlwm yog tsim kom muaj qhov sib nqus sib nqus nyob rau hauv winding los ntawm alternating tam sim no, ua rau lub rotor tig nyob rau hauv lub magnetic teb thiab tsim rotational torque. AC lub cev muaj zog feem ntau yog tsim los ntawm stator thiab rotor. Peb theem AC fais fab yog nkag mus rau hauv stator los ua kom muaj qhov sib nqus sib nqus; Muaj cov lus qhia tuav tau nruab rau hauv lub rotor. Thaum lub rotor rotates nyob rau hauv ib tug rotating magnetic teb, cov lus qhia tuav yog raug rau Ampere lub zog los tsim torque, tsav lub rotor tig.

DC lub cev muaj zog: DC lub cev muaj zog yog ib hom lub cev muaj zog raws li qhov sib nqus ntawm qhov tam sim no thiab lub zog ntawm cov hlau nplaum ntawm qhov tam sim no. Nws txoj haujlwm ua haujlwm yog tsim kom muaj qhov sib nqus ntawm lub stator thiab rotor ntawm lub cev muaj zog thaum siv tam sim no, uas siv lub zog ntawm lub zog rotor kom tig nws. DC lub cev muaj zog muaj peb ntu: stator, rotor, thiab commutator. Lub stator tsim ib qho chaw sib nqus tas li, thaum lub rotor tig nyob rau hauv lub zog ntawm qhov chaw sib nqus tas li thaum muaj qhov tam sim no dhau los ntawm nws. Lub luag haujlwm ntawm commutator yog los hloov qhov ncaj qha tam sim no ntawm cov khoom siv hluav taws xob mus rau hauv ib qho tam sim no ntawm cov txhuam hniav, txhawm rau tswj xyuas qhov kev taw qhia tas li ntawm tam sim no.

2, Cov qauv thiab kev ua haujlwm zoo
AC lub cev muaj zog: AC motors muaj cov qauv yooj yim, cov nqi tsim khoom tsawg, thiab kev lag luam txhim khu kev qha. Vim yog siv cov windings thiab rotating magnetic teb, AC motors muaj kev ua haujlwm siab thiab torque tso zis muaj peev xwm, ua rau lawv haum rau cov khoom siv loj thiab kev siv hnyav. Tsis tas li ntawd, AC motors kuj muaj kev tswj hwm kev ua tau zoo thiab tuaj yeem ua tiav ntau yam kev tswj hwm kev ceev los ntawm kev tswj cov khoom siv ceev xws li kev hloov pauv zaus.

DC lub cev muaj zog: DC motors muaj cov qauv tsim thiab cov nqi tsim khoom siab. Vim yog siv cov commutators thiab txhuam hniav, DC motors tsim qee qhov kev sib txhuam thiab kev poob thaum lub sijhawm ua haujlwm, ua rau qis qis dua. Txawm li cas los xij, DC motors muaj kev tswj hwm kev ceev thiab kev pib ua haujlwm, thiab tuaj yeem ua tiav cov zis tawm ntawm qhov qis qis, ua rau lawv tsim nyog rau cov xwm txheej uas xav tau kev tswj xyuas ceev thiab kev taw qhia. Tsis tas li ntawd, DC motors kuj muaj qhov zoo tshaj thiab rov qab muaj peev xwm.

3, Daim ntawv thov teb
AC lub cev muaj zog: AC motors tau siv dav hauv kev lag luam xws li lub zog, tshuaj, kev tsim kho, metallurgy, thiab kev thauj mus los vim lawv cov qauv yooj yim, tus nqi qis, kev ua haujlwm siab, thiab kev ua haujlwm zoo. Tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum tau muaj hwj chim loj, AC motors muaj qhov zoo. Tsis tas li ntawd, nrog rau kev txhim kho ntawm zaus hloov tshuab, kev tswj hwm kev ua tau zoo ntawm AC motors tau raug txhim kho ntxiv, nthuav lawv cov kev siv hauv kev tswj hwm kev tswj hwm thiab kev txuag hluav taws xob thiab kev txo qis.

DC lub cev muaj zog: Vim nws txoj kev tswj hwm kev ua tau zoo, pib ua haujlwm, thiab muaj peev xwm dhau, DC motors tau siv dav hauv cov ntawv thov uas xav tau kev tswj xyuas meej, xws li cov cuab yeej siv tshuab, textiles, luam ntawv, khoom siv kho mob, thiab lwm yam. , DC motors kuj tau siv dav vim tias lawv cov kev tswj xyuas ceev ceev thiab kev saib xyuas yooj yim. Tsis tas li ntawd, nrog kev tshwm sim thiab kev loj hlob ntawm brushless DC motors, lawv cov kev ua tau zoo tau ntxiv lawm, nthuav lawv cov kev siv hauv aerospace, tub rog thiab lwm yam.
