AC (alternating tam sim no) thiab DC (direct tam sim no) motors yog ob hom hluav taws xob motors siv nyob rau hauv ntau yam kev siv. Thaum ob hom motors ua haujlwm tib lub hom phiaj ntawm kev hloov hluav taws xob rau hauv lub tshuab hluav taws xob, lawv ua haujlwm ntawm cov qauv sib txawv thiab muaj cov yam ntxwv sib txawv.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm AC thiab DC motors nyob hauv hom tam sim no lawv siv. AC motors yog tsim los khiav ntawm alternating tam sim no, uas txhais tau hais tias cov kev taw qhia ntawm tam sim no hloov raws sij hawm. Ntawm qhov tod tes, DC motors yog powered los ntawm cov tam sim no ncaj qha, qhov twg cov ndlwg ntawm hluav taws xob nqi yog unidirectional.
Lwm qhov sib txawv tseem ceeb yog txoj hauv kev uas cov hlau nplaum tsim tawm hauv cov motors. Nyob rau hauv AC motors, lub magnetic teb yog tsim los ntawm alternating tam sim no ntws los ntawm stator windings, uas induces ib tug rotating magnetic teb. Qhov rotating magnetic teb no cuam tshuam nrog lub rotor los tsim cov lus tsa suab. Nyob rau hauv sib piv, DC motors cia siab rau ib tug mus tas li hlau nplaum los yog electromagnetic teb tsim los ntawm cov ncaj qha tam sim no los tsim cov tsim nyog sib nqus quab yuam rau kev sib hloov.
Lub tshuab tswj ceev kuj tseem sib txawv ntawm AC thiab DC motors. AC motors feem ntau vam khom ntau zaus los kho qhov nrawm, uas cuam tshuam txog kev hloov pauv zaus ntawm lub zog nkag. Hauv qhov sib piv, DC motors muab kev tswj ceev nrawm dua los ntawm kev tswj hwm ntawm cov khoom siv hluav taws xob.
Kev ua tau zoo thiab kev saib xyuas yuav tsum tau ua yog lwm yam uas tsim AC thiab DC motors sib nrug. AC motors feem ntau ua haujlwm tau zoo dua thiab yuav tsum muaj kev saib xyuas tsawg dua vim tsis muaj cov txhuam hniav thiab cov commutators, uas yog cov khoom siv hauv DC motors. Txawm li cas los xij, DC motors paub txog lawv txoj kev yooj yim thiab yooj yim ntawm kev tswj ceev.
Hauv cov ntsiab lus, qhov sib txawv ntawm AC thiab DC lub cev muaj zog yog los ntawm hom tam sim no lawv siv, cov txheej txheem ntawm magnetic teb tiam, kev ceev tswj mechanisms, thiab lawv cov kev ua tau zoo thiab kev saib xyuas. Kev nkag siab txog cov kev sib txawv no yog qhov tseem ceeb rau kev xaiv lub cev muaj zog tshaj plaws rau cov specs, vim txhua hom muaj nws tus kheej zoo thiab cov kev txwv.
