Raws li lub npe cuam tshuam, lub tshuab synchronous ib txwm muaj qee yam uas" synchronizes" lossis" tig" synchronously; seb nws yog lub tshuab synchronous lossis asynchronous, nws muaj tus stator thiab rotor; tus stator yog ib feem ntawm lub cav, thiab lub rotor yog ntuj. Nws yog ib feem uas tig tau. Tus stator tau muab faib ua ob hom: winding thiab hlau tub ntxhais, uas muaj cov haujlwm zoo ib yam. Thaum peb-theem hloov pauv tam sim no txuas nrog tus stator, tus stator yuav tsim lub tshuab sib nqus tig, raws li qhia hauv daim duab hauv qab no. (Tsuas yog lub tswv yim/tsis yooj yim li ntawd)
Kev sib hloov nrawm ntawm qhov chaw sib nqus stator sib txawv, thiab qhov zaus ntawm lub zog muab txiav txim siab "nrawm" ntawm qhov sib nqus sib nqus; lub rotor ntawm lub tshuab synchronous tuaj yeem nkag siab tias yog cov hlau nplaum ruaj khov (suav nrog cov tshuab hluav taws xob). Lub rotor ib txwm muaj cov hlau nplaum sib nqus, uas yog, N/S, tom qab ntawd qhov sib nqus sib nqus ntawm tus stator ib txwm nyiam qhov sib nqus ntawm lub rotor kom nws tig. Cov hlau nplaum txuas mus tas li hu ua synchronous motor vim tias qhov sib nqus ntawm qhov nrawm thiab qhov rotor nrawm ntawm qhov chaw xaiv yog tib yam, thiab ob qho tib si.
Qhov rov qab yog lub cav asynchronous, tab sis lub cav asynchronous tsis yooj yim li; lub rotor ntawm lub cev muaj zog asynchronous yog lub tshuab hluav taws xob luv luv, uas tsis muaj cov hlau nplaum sib nqus; qhov sib nqus sib nqus tsim tawm tom qab tus stator tau txhawb zog yuav txiav lub rotor winding, thiab qhov ua kom muaj qhov tam sim no yuav tshwm ntawm qhov cua, thiab lub rotor yuav muaj tam sim no Tom qab ntawd nws tuaj yeem tau txais kev nqis tes ua hluav taws xob kom ua kom nrawm dua. Txawm li cas los xij, hauv cov txheej txheem ntawm kev nce kev sib hloov ntawm lub rotor, ib zaug kev sib hloov ceev ntawm lub rotor sib npaug rau kev sib hloov nrawm ntawm tus stator sib nqus teb, ob qho sib npaug zoo li qub; nyob rau lub sijhawm no, qhov sib nqus sib nqus tig thiab lub rotor winding tsis muaj kev txiav tawm, thiab lub rotor yuav poob lub zog hluav taws xob (uas tuaj yeem nkag siab tias poob lub zog lossis nyiam) thiab qeeb, txawm tias tuaj yeem nkag siab zoo li&"; instantaneous chaw."
Thiab tsuas yog tom qab lub rotor txo qis, lub rotor thiab stator sib nqus teb nrawm nrawm sib txawv, thiab ob qho yuav muaj cov txheeb ze-ua kom qeeb thiab ua kom nrawm dua, ua kom nrawm dua tom qab sib txuas, thiab ua kom nrawm tom qab qeeb. Qhov no yog asynchronous lub cev muaj zog, rotor thiab sib nqus teb nrawm sib txawv.
