Tib-theem motors xav tau cov capacitors thaum peb-theem motors tsis xav tau vim lawv tsim thiab ua haujlwm.
Tib-theem motors ua haujlwm siv ib qho kev hloov tam sim no (AC) voltage qhov chaw. Txawm li cas los xij, qhov hluav taws xob tsim los ntawm qhov chaw no tsis zoo ib yam thiab tsis tas li muaj lub zog txaus los pib lub cev muaj zog. Capacitors tuaj yeem pab txhim kho qhov pib torque ntawm lub cev muaj zog los ntawm kev khaws cov hluav taws xob hluav taws xob thiab tso tawm thaum lub sijhawm tsim nyog. Lawv yeej tseem ceeb ua hauj lwm raws li ib tug voltage booster los pab lub cev muaj zog pib thiab ua hauj lwm smoothly.
Peb-theem lub cev muaj zog, ntawm qhov tod tes, siv peb qhov chaw hloov hluav taws xob tam sim no uas yog offset los ntawm ib leeg los ntawm 120 degrees. Qhov no tsim kom muaj qhov sib npaug thiab muaj zog hluav taws xob ntau dua, uas ua rau lub cev muaj zog pib thiab ua haujlwm zoo yam tsis tas yuav tsum muaj cov capacitors.
Nyob rau hauv cov ntsiab lus, qhov xav tau rau cov capacitors nyob rau hauv ib-theem motors yog vim muaj kev txwv ntawm AC voltage mov, thaum peb-theem motors ua hauj lwm zoo dua thiab zoo vim lawv tsim siv peb voltage qhov chaw uas nyob rau hauv sync.
