YVF series kuj tsis paub meej zaus ceev txoj cai siab voltage peb-theem asynchronous motors (thav duab loj 315 ~ 630) (tom qab no hu ua motors) yog cov khoom tshiab tsim los ntawm peb lub tuam txhab raws li kev lag luam xav tau. Thaum siv nrog lub zaus hloov pauv, lawv tuaj yeem ua tiav kev tswj hwm kev nrawm nrawm hauv ntau qhov sib txawv, ntawm qhov ntau zaus ntawm 5-50Hz yog qhov kev tswj hwm lub zog tsis tu ncua, thiab ntau zaus ntawm 50-100Hz yog qhov kev tswj hwm lub zog ceev. Nws yog ib qho khoom siv tsav zoo tshaj plaws kom tau raws li cov kev xav tau ntawm cov khoom siv ceev ceev.
Cov motors series no yog ua los ntawm cov khoom siv ua tib zoo xaiv thiab ua tau zoo. Lawv muaj cov yam ntxwv ntawm kev tswj ceev ceev, kev ua haujlwm siab, tsis tshua muaj suab nrov, tsis tshua muaj kev vibration, kev nyab xeeb thiab txhim khu kev qha, kev siv yooj yim thiab txij nkawm, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.
