Txoj cai ntawm asynchronous lub cev muaj zog

Daim ntawv thov ntawm Asynchronous Tsav

Asynchronous motors uas ua haujlwm raws li hluav taws xob motors. Vim hais tias lub rotor winding tam sim no yog induced, nws tseem hu ua induction motor. Asynchronous motors yog cov siv dav tshaj plaws thiab xav tau tshaj plaws ntawm txhua hom motors. Kwv yees li 90% ntawm cov tshuab siv hluav taws xob hauv ntau lub teb chaws yog asynchronous motors, ntawm cov me me asynchronous motors suav nrog ntau dua 70%. Nyob rau hauv tag nrho cov load ntawm lub hwj chim system, cov hluav taws xob noj ntawm asynchronous motors account rau ib tug ntau npaum li cas. Hauv Suav teb, kev siv hluav taws xob ntawm asynchronous motors suav nrog ntau dua 60% ntawm tag nrho cov khoom thauj.

Lub tswvyim ntawm asynchronous lub cev muaj zog

 

Lub asynchronous lub cev muaj zog yog AC lub cev muaj zog uas nws qhov sib piv ntawm qhov ceev ntawm qhov thauj khoom mus rau qhov zaus ntawm daim phiaj sib txuas tsis yog tus nqi tas li. Induction lub cev muaj zog yog asynchronous lub cev muaj zog nrog tsuas yog ib txheej ntawm windings txuas nrog lub hwj chim mov. Nyob rau hauv rooj plaub uas tsis ua rau kev nkag siab yuam kev thiab tsis meej pem, induction motors feem ntau hu ua asynchronous motors. Tus txheej txheem IEC tau hais tias lo lus "induction motor" yog siv los ua lub ntsiab lus ntawm "asynchronous motor" hauv ntau lub tebchaws, thaum lwm lub tebchaws tsuas yog siv lo lus "asynchronous motor" los sawv cev rau ob lub ntsiab lus no.

Txoj cai ntawm asynchronous lub cev muaj zog
Tom qab ib tug symmetrical voltage yog siv rau lub stator winding ntawm peb-theem asynchronous lub cev muaj zog, ib tug rotating huab cua sib nqus magnetic teb yog generated, thiab lub rotor winding conductor txiav lub magnetic teb los tsim ib tug induced muaj peev xwm. Lub rotor tam sim no yog tsim los ntawm luv luv Circuit Court ntawm rotor windings. Kev sib cuam tshuam ntawm lub rotor tam sim no thiab cov huab cua sib nqus magnetic teb generates electromagnetic torque, uas tsav lub rotor tig. Qhov ceev ntawm lub cev muaj zog yuav tsum qis dua qhov sib nqus ceev ntawm qhov sib nqus, vim tias tsuas yog nyob rau hauv txoj kev no tuaj yeem ua rau tus neeg xyuas pib rotor induce ib qho hluav taws xob muaj peev xwm los tsim cov rotor tam sim no thiab electromagnetic torque. Yog li lub cev muaj zog hu ua lub tshuab asynchronous, tseem hu ua induction motor.
