Dab tsi yog Peb-theem Asynchronous Tsav

Peb-theem asynchronous lub cev muaj zog yog ib hom induction lub cev muaj zog uas yog siv los ntawm 380V peb-theem AC tam sim no (nrog rau theem sib txawv ntawm 120 degrees). Vim lub fact tias lub rotor thiab stator ntawm peb-theem asynchronous lub cev muaj zog tig nyob rau hauv tib txoj kev tab sis nyob rau hauv sib txawv speeds, muaj ib tug plam tus nqi, li no nws yog hu ua peb-theem asynchronous lub cev muaj zog. Qhov ceev ntawm lub rotor ntawm peb-theem asynchronous lub cev muaj zog yog qis dua li ntawm cov rotating magnetic teb. Lub rotor winding generates electromotive quab yuam thiab tam sim no vim qhov txheeb ze zog nrog lub magnetic teb, thiab interacts nrog lub magnetic teb los tsim electromagnetic torque, ua tiav lub zog hloov dua siab tshiab.
Piv nrog ib-theem asynchronous motors, peb-theem asynchronous motors muaj kev ua haujlwm zoo dua thiab tuaj yeem txuag tau ntau yam ntaub ntawv. Raws li cov qauv rotor sib txawv, peb-theem asynchronous motors tuaj yeem muab faib ua hom tawb thiab hom kab mob. Lub asynchronous lub cev muaj zog nrog tawb rotor muaj cov qauv yooj yim, txhim khu kev qha, lub teeb yuag, thiab tus nqi qis, thiab tau siv dav. Nws lub ntsiab tsis zoo yog qhov nyuaj hauv kev tswj ceev. Lub rotor thiab stator ntawm lub qhov txhab peb-theem asynchronous lub cev muaj zog kuj tau nruab nrog peb-theem windings thiab txuas nrog cov resistors sab nraud los ntawm cov hlua khi thiab txhuam. Kho qhov tsis kam ntawm qhov sib txawv ntawm cov resistor tuaj yeem txhim kho qhov pib ua haujlwm ntawm lub cev muaj zog thiab tswj nws qhov nrawm.
