AC thiab DC motors yog ob hom lub cev muaj zog uas siv ntau yam kev siv. Nkag siab qhov sib txawv ntawm ob hom motors yog qhov tseem ceeb rau kev xaiv lub cev muaj zog rau ib daim ntawv thov tshwj xeeb.
Qhov sib txawv tseem ceeb ntawm AC thiab DC motors yog hom tam sim no lawv siv. Raws li lub npe qhia, AC motors khiav ntawm alternating tam sim no, thaum DC motors khiav ntawm ncaj qha tam sim no. Qhov sib txawv tseem ceeb hauv hom tam sim no lawv siv muaj qhov cuam tshuam loj rau lawv cov kev ua tau zoo thiab kev siv.
AC motors paub txog lawv txoj kev yooj yim thiab kev ntseeg tau. Lawv tau siv dav hauv cov khoom siv hauv tsev, kev siv tshuab thiab HVAC systems. AC motors muaj peev xwm ua haujlwm ntawm qhov ceev tsis tu ncua, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau kev ua haujlwm tas mus li thiab zoo ib yam. Ib qho txiaj ntsig tseem ceeb ntawm AC motors yog qhov muaj peev xwm hloov tau yooj yim ntawm kev sib hloov ceev los ntawm kev kho qhov zaus ntawm AC lub zog.
DC motors, ntawm qhov tod tes, paub txog lawv lub peev xwm los muab kev ceev ceev thiab tswj txoj haujlwm. Lawv feem ntau siv rau hauv daim ntawv thov xws li tsheb fais fab, neeg hlau thiab tshuab conveyor. DC motors muab kev tswj ceev ceev thiab kev tswj lub zog, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau kev tswj xyuas qhov tseeb.
Structurely, AC motors feem ntau siv lub induction motor tsim, qhov twg ib tug rotating magnetic teb yog induced los ntawm cov alternating tam sim no nyob rau hauv lub stator winding. Ib qho DC lub cev muaj zog, ntawm qhov tod tes, siv lub commutator thiab txhuam los hloov tam sim no rau hauv kev sib hloov.
Thaum nws los txog rau kev saib xyuas, AC motors feem ntau xav tau kev saib xyuas tsawg dua li DC motors vim lawv cov qauv yooj yim thiab tsawg dua qhov txav. Txawm li cas los xij, DC motors muab kev ua haujlwm zoo dua thiab kev tswj hwm, tshwj xeeb tshaj yog nyob rau hauv kev siv ceev sib txawv.
Hauv cov ntsiab lus, thaum ob qho tib si AC thiab DC motors muaj lawv tus kheej cov yam ntxwv thiab qhov zoo, kev xaiv ntawm ob yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov. Kev nkag siab txog qhov sib txawv ntawm AC thiab DC motors yog qhov tseem ceeb rau kev xaiv lub cev muaj zog tshaj plaws rau ib qho kev siv tshwj xeeb. Txawm hais tias kev ua haujlwm tsis tu ncua lossis kev tswj xyuas qhov tseeb, qhov kev xaiv zoo ntawm AC thiab DC motors tuaj yeem muaj kev cuam tshuam loj rau kev ua haujlwm thiab kev ua haujlwm ntawm koj lub cev.
