Covinduction lub cev muaj zogtsuas yog electrified lub stator, raws li txoj kev xav ntawm magnetic muaj peev xwm thiabmuaj peev xwm tshuav, electromagnetic induction thiab tag nrho tam sim no txoj cai.Qhov no zoo ib yam nrog lub hauv paus ntsiab lus ntawm kev ua haujlwmtransformer, yog li kev nkag siab lub cev muaj zog tuaj yeem pib los ntawm kev nkag siab txog kev ua haujlwm ntawm transformer.
Txawm li cas los xij, tseem muaj qhov sib txawv loj ntawm asynchronous lub cev muaj zog thiab transformer hauv qhov tseem ceeb
Ua ntej, lub peev xwm sib nqus ntawm covasynchronouslub cev muaj zog yog cov khoom sib nqus muaj peev xwm ntawm peb-theem winding, uas yog lub peev xwm sib nqus sib nqus, thiab tsim cov hlau nplaum yog ib qho rotating magnetic teb, uas ua kom muaj kev sib hloov ntawm rotor ib feem;Lub peev xwm sib nqus nyob rau hauv lub transformer yog cov mem tes vibration magnetic peev xwm, thiab txawmpeb-theem transformerkuj suav nrog theem.Qhov thib ob, lub transformer yog ntau dua ntawm kev hloov pauv ntawm lub zog, uas yog, hloov hluav taws xob hloov hluav taws xob, yog qhov hloov pauv hluav taws xob;Lub asynchronous lub cev muaj zog tsis tsuas yog muajlub zog hloov, tab sis kuj muaj lub luag haujlwm tseem ceeb dua, uas yog, hloov hluav taws xob hluav taws xob mus rau lub zog siv tshuab.
Qhov yooj yim electromagnetic relation ntawm tsis muaj-load thiab load lag luam ntawm peb-theem asynchronous lub cev muaj zog yog lub hauv paus ntsiab lus ntawm asynchronous lub cev muaj zog.
Hauv kev ua haujlwm tsis muaj kev thauj khoom, qhov ceev ntawm lub asynchronous lub cev muaj zog nyob ze rau qhov nrawm nrawm, lub rotor tam sim no nyob ze rau xoom, thiab cov stator tam sim no yog kwv yees li ntawm qhov sib npaug ntawm qhov excitation tam sim no (yog li ntau zaus, tib neeg yuav ntsuas qhov loj me. ntawm lub cev muaj zog tsis muaj load tam sim no los ntawm qhov loj ntawm qhov excitation tam sim no).Thaum lub load khiav, qhov ceev yuav txo, tus nqi nplawm nce (slip yog tus yam ntxwv ntawm asynchronous motors), thiab tus txheeb ze zog ntawm lub rotating magnetic teb thiab lub rotor.windingnce.Thaum lub hwj huam mov voltage yog ntsuas voltage, qhov to ntawm impedance voltage poob hauv statorwindingyog me me, thiab cov huab cua sib nqus magnetic teb yeej tsis hloov.Los ntawm lub luag hauj lwm ntawm magnetic muaj peev xwm tshuav thiabelectromagnetic induction, lub zog hluav taws xob yog input los ntawm lub hwj chim mov mus rau lubstator winding, uas qhia txog lub zog ntawm lub cev muaj zog.Mechanical zog yog tso tawm los ntawm lubrotor ncej, thiab qhov Performance index uas txiav txim siab lub zog tso zis muaj peev xwm ntawm lub cev muaj zog yog lub cev muaj zog efficiency.
