AC lub cev muaj zog "yog cov cuab yeej siv tshuab siv los hloov lub zog siv hluav taws xob thiab hloov hluav taws xob tam sim no rau ib leeg. Vim muaj kev txhim kho tseem ceeb ntawm AC lub zog hluav taws xob, AC motors tau dhau los ua cov motors feem ntau siv, piv nrog DC motors, AC motors muaj ib Cov qauv yooj yim, yooj yim rau kev tsim khoom, muaj zog dua, thiab tuaj yeem ua tau yooj yim rau hauv high-speed, high-voltage, siab tam sim no, thiab loj muaj peev xwm motors vim tsis muaj commutator (saib DC motor commutation). ntawm AC lub cev muaj zog yog loj heev, los ntawm ob peb watts mus rau kaum tawm txhiab kilowatts, thiab txawm ntau lab kilowatts Thaum ntxov 1980s, qhov loj tshaj plaws chav turbine generator tau mus txog 1.5 lab kilowatts.
