Peb -Phase Asynchronous AC Tsav yog dab tsi?

Peb lub-theem asynchronous lub cev muaj zog yog ib hom induction lub cev muaj zog los ntawm peb 380V alternating tam sim no (120-degree theem sib txawv) ib txhij. Vim hais tias lub rotor thiab stator rotating magnetic teb ntawm ib tug peb -theem asynchronous lub cev muaj zog tig nyob rau hauv tib txoj kev tab sis nyob rau hauv sib txawv speeds, plam tshwm sim, li no lub npe "peb-theem asynchronous lub cev muaj zog." Lub rotor ceev yog qis dua qhov sib nqus teb ceev. Lub rotor windings tsim electromotive quab yuam thiab tam sim no vim qhov txheeb ze txav ntawm lawv thiab cov magnetic teb, thiab cuam tshuam nrog cov magnetic teb los tsim electromagnetic torque, yog li ua tiav lub zog hloov dua siab tshiab.

Piv rau ib zaug xwb -theem asynchronous motors, peb -theem asynchronous motors muaj kev ua haujlwm zoo dua thiab txuag ntawm ntau yam ntaub ntawv. Raws li cov qauv rotor, peb -theem asynchronous motors tuaj yeem muab faib ua squirrel- tawb thiab qhov txhab- hom rotor. Squirrel-cage asynchronous motors yog qhov yooj yim hauv cov qauv, txhim khu kev qha hauv kev ua haujlwm, hnav, thiab pheej yig, thiab tau siv dav. Lawv lub ntsiab tsis zoo yog qhov nyuaj ntawm kev tswj ceev. Qhov mob-rotor peb-theem asynchronous motors, zoo li lub stator, kuj muaj peb-theem windings ntawm lub rotor, uas txuas nrog rau sab nraud rheostat ntawm cov ntiv tes xoo 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.
