Thaum nws los txog rau cov cav hluav taws xob, ob hom uas feem ntau muab piv rau yog cov cav asynchronous thiab cov cav synchronous. Ob qho tib si muaj lawv tus kheej cov yam ntxwv thiab kev siv, yog li nws tseem ceeb heev kom nkag siab txog qhov sib txawv ntawm ob qho.
Lub cev muaj zog asynchronouss, tseem hu ua induction motors, yog siv dav hauv kev lag luam thiab kev lag luam. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm asynchronous motors yog lawv cov qauv yooj yim thiab ruaj khov, uas ua rau lawv pheej yig thiab yooj yim rau kev tswj hwm. Cov motors no tsis xav tau kev sib txuas ntawm lub cev ntawm rotor thiab stator, ua rau lawv zoo tagnrho rau cov ntawv thov uas qhov ceev tas li tsis tseem ceeb. Asynchronous motors kuj paub txog lawv lub zog pib siab, ua rau lawv haum rau cov ntawv thov xws li cov siv conveyor thiab twj tso kua mis.
Cov cav synchronous, ntawm qhov tod tes, paub txog lawv qhov kev tswj ceev thiab kev ua haujlwm zoo. Tsis zoo li cov cav asynchronous, cov cav synchronous khiav ntawm qhov ceev tas li tsis hais txog qhov thauj khoom. Qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau qhov ceev tas li thiab meej, xws li cov txheej txheem kev lag luam thiab kev tsim hluav taws xob. Cov cav synchronous kuj paub txog lawv qhov kev kho qhov yuam kev fais fab, uas ua rau lawv ua haujlwm tau zoo dua hauv kev siv hluav taws xob.
Hais txog kev tsim kho, cov asynchronous motors yooj yim dua thiab muaj zog dua, thaum cov synchronous motors nyuaj dua thiab xav tau cov khoom ntxiv xws li DC fais fab mov rau lub rotor. Qhov no ua rau cov synchronous motors kim dua thiab tsis tshua muaj nyob rau hauv kev siv hauv kev lag luam dua li cov asynchronous motors.
Hauv kev xaus, qhov kev xaiv ntawm asynchronous thiab synchronous motors nyob ntawm qhov xav tau tshwj xeeb ntawm daim ntawv thov. Asynchronous motors muaj txiaj ntsig zoo dua thiab tsim nyog rau cov ntawv thov uas qhov kev hloov pauv ceev tau txais, thaum synchronous motors zoo tagnrho rau cov ntawv thov uas xav tau kev tswj hwm qhov ceev thiab kev ua haujlwm siab. Kev nkag siab txog qhov sib txawv ntawm ob hom motors no yog qhov tseem ceeb rau kev xaiv qhov kev xaiv tsim nyog tshaj plaws rau ib daim ntawv thov tshwj xeeb.
