1. Cov qauv kev ua haujlwm sib txawv
DC lub cev muaj zog yog lub tshuab hluav taws xob uas siv los ntawm DC fais fab mov. Nws txoj haujlwm ua haujlwm yog raws li Faraday txoj cai ntawm electromagnetic induction thiab Ampere txoj cai. Thaum DC fais fab mov dhau lawm, qhov tam sim no dhau los ntawm stator coil thiab rotor coil ntawm lub cev muaj zog. Nyob rau hauv stator coil, tam sim no generates ib magnetic teb, thiab nyob rau hauv lub rotor kauj, vim muaj kev cuam tshuam ntawm cov tam sim no thiab cov magnetic teb, ib tug torque yog generated, ua rau lub cev muaj zog tig.
AC lub cev muaj zog yog lub tshuab hluav taws xob uas siv los ntawm AC fais fab mov. Nws txoj haujlwm ua haujlwm yog raws li Faraday txoj cai ntawm electromagnetic induction thiab Hall effect. Thaum cov khoom siv hluav taws xob AC hla los ntawm stator kauj ntawm lub cev muaj zog, nws tsim ib qho chaw sib nqus sib nqus, uas cuam tshuam nrog cov hlau nplaum hauv lub rotor coil, yog li tsim kom muaj kev sib hloov torque, ua rau lub cev muaj zog tig.
2. Cov qauv sib txawv
DC motors feem ntau yog tsim los ntawm stators, rotors, txhuam, shafts thiab vaj tse. Lub stator thiab rotor muaj cov coils thiab hlau nplaum sib npaug. Nyob rau hauv lub cev muaj zog, lub stator kauj yog tsau rau lub cev muaj zog vaj tse, thaum lub rotor kauj yog mounted rau lub cev muaj zog ncej. Cov txhuam hniav yog siv los txuas cov stator coil thiab cov khoom siv hluav taws xob sab nraud los hloov hluav taws xob hluav taws xob rau hauv lub zog siv tshuab.
AC motors muaj cov qauv yooj yim thiab feem ntau yog tsim los ntawm stators, rotors, capacitors, shafts thiab vaj tse. Lub stator thiab rotor kuj muaj coils thiab hlau nplaum raws li. Hauv AC motors, rotor coil feem ntau yog ua los ntawm txhuas thiab txuas nrog stator kauj los ntawm lub capacitor.
3. Cov ntawv thov sib txawv
DC motors tau dav siv nyob rau hauv ntau yam kev lag luam thiab cov khoom siv hauv tsev, xws li kiv cua, tshuab luam ntawv, cov cuab yeej hluav taws xob, thiab lwm yam. Lawv muaj cov yam ntxwv ntawm kev ua haujlwm siab, siab torque, yooj yim tswj kev ceev, thiab lwm yam, yog li lawv tsis tuaj yeem hloov tau ntau zaus.
AC motors feem ntau yog siv hauv cov khoom siv hauv tsev, cov khoom siv hauv tsev thiab lwm yam, xws li cov kiv cua hluav taws xob, tshuab ntxhua khaub ncaws, compressors, thiab lwm yam. Vim tias AC motors muaj cov yam ntxwv ntawm kev ua haujlwm siab thiab tsis tshua muaj suab nrov, lawv tau siv dav hauv cov khoom siv hauv tsev.
Raws li peb txhua tus paub, motors yog cov khoom tseem ceeb ntawm cov khoom siv hauv tsev. Los ntawm cov tub yees mus rau shavers, lawv txhua tus xav tau lub cev muaj zog los tsav lawv. Yog tsis muaj motors, cov khoom siv hauv tsev los ua cov khoom dai. Nws yog ib qho khoom siv hluav taws xob uas paub txog kev hloov pauv lossis kev sib kis ntawm hluav taws xob hluav taws xob raws li txoj cai ntawm electromagnetic induction. Lub cev muaj zog tuaj yeem muab faib ua ntau hom raws li kev faib tawm sib txawv. DC motors thiab AC motors yog ob hom kev faib tawm. Yog li, dab tsi yog qhov txawv ntawm DC motors thiab AC motors?
Qhov tseeb, qhov tseem ceeb tshaj qhov sib txawv ntawm DC motors thiab AC motors yog hom fais fab mov. Ib tug yuav tsum tau DC fais fab thiab lwm yam yuav tsum tau AC zog. Dab tsi hauv qab no yog qhov sib txawv ntawm kev ua haujlwm thiab kev tswj cov qauv.
