Vim li cas AC asynchronous motor hu ua asynchronous motor? Vim tias qhov ceev ntawm AC asynchronous lub cev muaj zog tsawg dua qhov nrawm ntawm qhov sib nqus sib nqus, nws hu ua asynchronous motor. Nws yeej yog tib yam li covinduction lub cev muaj zog.
AC asynchronous lub cev muaj zogmuab faib ua induction motors thiab AC commutator motors. Induction motors yog feem ntau siv. Induction motors feem ntau tuaj yeem hu ua asynchronous motors yam tsis muaj kev nkag siab yuam kev lossis tsis meej pem.
Induction motors tau muab faib ua ib-theem asynchronous motors thiab AC / DC dual-purpose motors
Lub hauv paus ntsiab lus ua haujlwm ntawm AC asynchronous lub cev muaj raws li hauv qab no:
- Thaum peb-theem asynchronous lub cev muaj zog txuas nrog peb-theem AC fais fab mov, peb-theem stator winding ntws los ntawm peb-theem symmetrical tam sim no los ua kom muaj peb-theem sib nqus motive quab yuam thiab tsim kom muaj kev sib nqus sib nqus.
- Lub rotating magnetic teb muaj ib tug txheeb ze txiav suab nrog lub rotor conductor. Raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, rotor conductor generates ib tug induced electromotive quab yuam thiab induced tam sim no.
- Raws li txoj cai ntawm electromagnetic quab yuam, tam sim no-nqa rotor conductor yog ua los ntawm electromagnetic quab yuam nyob rau hauv magnetic teb, tsim ib tug electromagnetic torque, tsav lub rotor tig. Thaum lub cev muaj zog ncej nqa ib tug neeg kho tshuab load, nws outputs mechanical zog rau sab nraud.
Cov yam ntxwv ntawm AC asynchronous motors yog raws li nram no:
- Asynchronous motors yog AC motors, thiab qhov sib piv ntawm lawv cov ceev nyob rau hauv load mus rau zaus ntawm cov kab hluav taws xob sib txuas tsis yog ib qho kev sib raug zoo. Nws hloov nrog qhov loj ntawm lub load. Qhov ntau dua qhov load torque, qhov qis rotor ceev.
- Lub stator winding ntawm ib qho zoo tib yam asynchronous lub cev muaj zog txuas nrog AC lub zog hluav taws xob, thiab lub rotor winding tsis tas yuav txuas nrog lwm qhov chaw siv hluav taws xob. Yog li ntawd, nws muaj qhov zoo ntawm cov qauv yooj yim, yooj yim tsim, siv thiab txij nkawm, txhim khu kev qha lag luam, me me loj thiab tus nqi qis.
- Asynchronous motors muaj kev ua haujlwm siab dua thiab ua haujlwm zoo dua qub. Lawv khiav ntawm qhov ceev tsis tu ncua los ntawm tsis muaj-load mus rau tag nrho-load, thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev lag luam thiab kev ua liaj ua teb feem ntau.
- Asynchronous motors yog ib qho yooj yim los tsim ntau hom kev tiv thaiv kom tau raws li qhov xav tau ntawm qhov sib txawv ib puag ncig. Thaum lub asynchronous lub cev muaj zog khiav, nws yuav tsum nqus reactive excitation zog los ntawm daim phiaj hluav taws xob kom deteriorate lub zog ntawm daim phiaj fais fab.
- Qhov ceev ntawm lub asynchronous lub cev muaj zog muaj qee qhov kev sib raug zoo nrog kev ceev ntawm nws cov rotating magnetic teb, thiab nws cov kev tswj ceev ceev tsis zoo. Rau kev thauj mus los machinery, dov mills, loj tshuab cuab yeej, luam ntawv thiab dyeing thiab papermaking machinery uas yuav tsum tau ib tug dav thiab du kev ceev tswj ntau yam, nws yog ntau yig thiab yooj yim rau siv.DC motors.
- Nrog rau kev txhim kho cov khoom siv hluav taws xob siab thiab AC ceev cov txheej txheem, kev tswj hwm kev ua tau zoo thiab kev lag luam ntawm asynchronous motors haum rau kev tswj ceev nrawm yog piv rau cov DC motors.AC asynchronous motors tau siv dav hauv cov khoom siv hauv tsev xws li hluav taws xob kiv cua, tub yees, tshuab ntxhua khaub ncaws, cua txias, tshuab ziab khaub ncaws, tshuab ntxhua khaub ncaws, tshuab ntxhua khaub ncaws, tshuab ntxhua khaub ncaws. processors, thiab ntau yam khoom siv hluav taws xob thiab cov khoom siv hluav taws xob me me.
