1, AC asynchronous lub cev muaj zog

AC asynchronous lub cev muaj zog yog ib tug ua AC voltage lub cev muaj zog, uas yog dav siv nyob rau hauv hluav taws xob kiv cua, tub yees, tshuab ntxhua khaub ncaws, cua txias, hairdryers, nqus tsev vacuum, ntau hoods, tshuab ntxhua khaub ncaws, hluav taws xob tshuab xaws, khoom noj khoom haus machinery thiab lwm yam khoom siv hauv tsev. nrog rau ntau yam khoom siv hluav taws xob thiab cov khoom siv hluav taws xob me me.

AC asynchronous lub cev muaj zog yog muab faib ua induction motor thiab AC commutator motor.Induction lub cev muaj zog muab faib ua ib-theem asynchronous lub cev muaj zog, AC / DC lub cev muaj zog thiab lub cev muaj zog.

Qhov ceev ntawm lub cev muaj zog (rotor ceev) yog tsawg tshaj li qhov ceev ntawm lub rotating magnetic teb, yog li nws yog hu ua asynchronous motor.Nws yog tib yam li induction motor.S = (ns-n) / NS.S yog tus nqi swb,

NS yog qhov sib nqus nrawm thiab N yog qhov ceev rotor.

Lub hauv paus ntsiab lus:

1. 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 magnetomotive force (stator rotating magnetomotive force) tsim los ntawm peb-theem symmetrical tam sim no thiab generates rotating magnetic teb.

2. Lub rotating magnetic teb muaj txheeb ze txiav motion nrog rotor neeg xyuas pib.Raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, rotor conductor generates induced electromotive force thiab induced tam sim no.

3. Raws li txoj cai ntawm electromagnetic quab yuam, tam sim no nqa rotor conductor yog cuam tshuam los ntawm electromagnetic quab yuam nyob rau hauv magnetic teb los tsim electromagnetic torque thiab tsav lub rotor tig.Thaum muaj ib tug neeg kho tshuab load ntawm lub cev muaj zog ncej, nws yuav output mechanical zog sab nraud.

Asynchronous lub cev muaj zog yog ib hom AC lub cev muaj zog, thiab qhov sib piv ntawm kev ceev hauv qab thauj khoom mus rau qhov zaus ntawm kev sib txuas hluav taws xob tsis tas li.Nws kuj hloov nrog qhov loj ntawm lub load.Qhov ntau dua qhov load torque, qhov qis rotor ceev.Asynchronous lub cev muaj xws li induction lub cev muaj zog, muab ob npaug rau induction lub cev muaj zog thiab AC commutator lub cev muaj zog.Induction lub cev muaj zog yog feem ntau siv.Feem ntau nws tuaj yeem raug hu ua asynchronous lub cev muaj zog yam tsis muaj kev nkag siab yuam kev lossis tsis meej pem.

Lub stator winding ntawm lub cev asynchronous zoo tib yam 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 siv, siv thiab txij nkawm, txhim khu kev qha lag luam, tsis zoo thiab tus nqi qis.Asynchronous lub cev muaj zog muaj kev ua haujlwm siab thiab ua haujlwm zoo.Nws khiav ntawm qhov ceev tsis tu ncua los ntawm tsis muaj kev thauj khoom mus rau tag nrho cov khoom thauj, uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev lag luam thiab kev ua liaj ua teb feem ntau.Asynchronous motors kuj tseem yooj yim los tsim ntau hom kev tiv thaiv kom tau raws li qhov xav tau ntawm qhov sib txawv ntawm ib puag ncig.Thaum lub asynchronous lub cev muaj zog khiav, lub reactive excitation zog yuav tsum tau absorbed los ntawm lub hwj chim daim phiaj kom deteriorate lub hwj chim ntawm daim phiaj.Yog li ntawd, synchronous motors feem ntau yog siv los tsav lub zog siab thiab cov cuab yeej siv qis qis xws li pob zeb thiab compressors.Vim tias qhov ceev ntawm asynchronous lub cev muaj zog muaj qee qhov kev sib raug zoo nrog nws cov kev sib nqus sib nqus nrawm, Nws cov kev tswj ceev ceev tsis zoo (tshwj tsis yog AC commutator motor).DC lub cev muaj zog yog kev lag luam ntau dua thiab yooj yim rau kev thauj mus los machinery, dov zeb, cov cuab yeej siv tshuab loj, luam ntawv thiab dyeing thiab papermaking machinery xav tau ntau yam kev tswj ceev ceev.Txawm li cas los xij, nrog kev txhim kho ntawm cov khoom siv hluav taws xob muaj zog thiab AC ceev tswj kev ua haujlwm, kev tswj hwm kev ua haujlwm nrawm thiab kev lag luam ntawm asynchronous lub cev muaj zog tsim nyog rau kev tswj ceev nrawm yog piv rau DC lub cev muaj zog.
