Ib-theem asynchronous motors feem ntau muaj xws li stator, stator windings, rotor, rotor windings, pib ntaus ntawv thiab kawg npog. Nws cov qauv yooj yim zoo ib yam li peb-theem asynchronous motors. Feem ntau, lub tawb rotor yog siv, tab sis lub stator winding yog txawv, feem ntau tsuas muaj ob pawg ntawm windings, ib tug yog hu ua lub ntsiab winding (tseem hu ua lub winding ua hauj lwm los yog khiav winding), thiab lwm yam yog hu ua lub auxiliary winding ( kuj hu ua start winding lossis auxiliary winding). Thaum lub zog ib-theem txuas nrog lub ntsiab winding, ib qho chaw sib nqus yuav raug tsim, tab sis txoj hauj lwm ntawm qhov chaw sib nqus no hauv qhov chaw yuav tsis hloov. Qhov loj thiab cov kev taw qhia ntawm lub generated magnetic teb yog zoo li sinusoidal alternating tam sim no. Nws yog ib qho chaw sib nqus sib nqus uas hloov pauv raws sijhawm raws li kev cai sinusoidal lub sijhawm. Qhov sib nqus teb tuaj yeem suav tau tias yog kev sib txuas ntawm ob qhov sib nqus sib nqus nrog sib npaug sib hloov ceev thiab kev sib hloov kev sib hloov. Yog li ntawd, ob lub electromagnetic torques ntawm tib qhov loj thiab cov lus qhia rov qab yog tsim rau ntawm lub rotor, thiab qhov tshwm sim torque yog sib npaug rau xoom, yog li lub rotor tsis tuaj yeem pib ntawm nws tus kheej.
Txhawm rau ua kom lub cev muaj zog pib ua haujlwm tau zoo, feem ntau lub ntsiab winding thiab cov pab cuam winding muaj qhov sib txawv ntawm qhov sib txawv ntawm 90 ° nyob rau hauv stator, thiab ob pawg windings txuas nrog alternating tam sim no nrog rau theem sib txawv ntawm 90 ° mus txog. qhov pib ntaus ntawv, yog li ntawd ob pawg ntawm windings Tam sim no muaj ib theem sib txawv nyob rau hauv lub sij hawm. Qhov pib winding tam sim no yog 90 ° ua ntej ntawm kev ua haujlwm winding tam sim no. Thaum ob lub voj voog hla mus rau ob lub voj voog uas sib nrug ntawm 90 ° nyob rau hauv qhov chaw, lub zog sib nqus sib nqus yuav raug tsim. Lub luag hauj lwm ntawm lub tawb rotor nyob rau hauv lub rotating magnetic teb Nyob rau hauv cov xwm txheej, ib tug pib torque yog generated thiab cov kev sib hloov pib los ntawm nws tus kheej ntawm ib tug ceev qis tshaj ntawm rotating magnetic teb.
