Lub cev muaj zog hluav taws xob muaj cov rotor tso rau hauv lub teb kev sib nqus. Nyob rau hauv cov cawv ntawm no rotating teb sib nqus, lub rotor kis tau cov torque, ua rau nws tig. Asynchronous motors muaj thoob plaws ntau lub zog ntau, los ntawm ob peb watts mus rau kaum ntawm txhiab tus kilowatts, muab lub zog rau ntau yam khoom siv khoom siv neeg thiab tsev neeg.
Lub cev muaj zog hluav taws xob (feem ntau hu ua "lub cev muaj zog") yog lub zog hluav taws xob uas hloov dua siab tshiab lossis cov chaw xa hluav taws xob raws li cov hauv paus ntawm hluav taws xob induction. Nws lub luag haujlwm tseem ceeb yog los tsim tsav lub zog, ua haujlwm raws li lub zog hluav taws xob rau cov khoom siv hluav taws xob lossis ntau yam khoom siv.
Lub sijhawm ua haujlwm ntawm lub tshuab hluav taws xob yog hloov pauv hluav taws xob lub zog mus rau hauv lub zog tshuab hluav taws xob.
Ib lub zog hluav taws xob feem ntau muaj hluav taws xob winding lossis faib cov pob zeb winding los tsim cov pob zeb sib nqus, rotating armiture lossis rotor, thiab lwm yam khoom siv. Nyob rau hauv cov cawv ntawm lub rotating sib nqus daim teb tsim los ntawm lub stator windings, tam sim no ntws los ntawm archrel {}} tawb txhuas ncej. Qhov kev cuam tshuam tam sim no nrog cov chaw sib nqus, ua rau armature kom tig.

Cov txheej txheem no tseem txhim kho lub zog tag nrho lub zog ntawm cov qauv rwb thaiv tsev.
4. Xyuas kom muaj kev sib txuam zoo ntawm cov inverter, cable, thiab txwv qhov ntev ntawm cov xaim ntawm lub cev muaj zog thiab lub zog.
Vim tias impedance mismatch hauv cov kab hluav taws xob, cov overvoltage amplitude ntawm lub zog nce nrog cov cable ntawm inverter thiab lub cev muaj zog, uas yooj yim ua rau muaj kev tshem tawm ib nrab. Yog li ntawd, raws li cov yam ntxwv tshwj xeeb ntawm cov hluav taws xob sib txawv thiab qhov ntev yuav tsum tau txo kom ntau li ntau tau los ntawm lub cev muaj zog, yog li txuas lub cev muaj zog. Lub zog sib txuas rau cov khoom muaj zog sib txawv feem ntau yuav tsum muaj cov cable tshwj xeeb, tseem muaj cov kab ke tshwj xeeb, uas yog ntawm 3p+3 n / e series. Qhov no txhais tau tias tus thawj {{5 5}} Kev kho teeb tsa cais lub mis me los ua peb tus neeg cais.
