Ma capacitor a filimu yopyapyala ndi gawo lowunikidwa kwambiri m'mabwalo amagetsi ndipo ali ndi ubwino wokhala ndi kukhazikika kwakukulu komanso moyo wautali. Malinga ndi mitundu yosiyanasiyana ya mabwalo ogwiritsira ntchito, ma capacitor a filimu amatha kugawidwa m'magulu monga ma DC circuits ndi ma AC circuits. Mu ma DC circuits, ma capacitor ake a filimu amagwiritsidwa ntchito makamaka pantchito monga kuletsa, kusalala, ndi kusunga mphamvu, pomwe mu ma AC circuits, ali ndi udindo waukulu woyimitsa kusokoneza kwa ma frequency apamwamba, kukonza mphamvu, ndi ma starting motors. Makamaka mu ma motor drive system, ma capacitor a mafilimu ali ndi mawonekedwe a high gain ndi high voltage resistance, zomwe zimapangitsa kuti akhale chiwongolero panthawi yoyambira ndi kugwira ntchito kwa motor. Nkhaniyi ikuyang'ana kwambiri pakugwiritsa ntchito ndi ubwino wa ma metallized film capacitors poyambira motor.
01 Kugwiritsa ntchito ma capacitor a filimu yachitsulo mu ma drive a mota ndikuthetsa mavuto
Mu makina oyendetsa magalimoto, ma capacitor a filimu amagwiritsidwa ntchito mbali ya DC ndi mbali ya AC motsatana, kuthetsa mavuto ambiri.

| Kusinthasintha kwa mphamvu yamagetsi yosalala | Pewani kulephera kwa makina oyendetsa galimoto chifukwa cha kusakhazikika kwa magetsi |
| Mphamvu yokhazikika | Onetsetsani kuti makina oyendetsa mota amagwira ntchito bwino pamalo okhazikika amagetsi |

| Chepetsani phokoso ndi kugwedezeka | Kuwongolera kukhazikika kwa injini ndikuwonetsetsa kuti injiniyo ikugwira ntchito bwino |
| Sinthani mphamvu yamagetsi | Kuchepetsa kutayika kwa mphamvu ndikuwonjezera magwiridwe antchito onse |
02 Kuyerekeza kwa ma capacitor a filimu yachitsulo ndi ma capacitor a electrolytic a aluminiyamu
Ma capacitor a filimu opangidwa ndi zitsulo ali ndi ubwino woonekeratu kuposa ma capacitor a electrolytic a aluminiyamu pankhani ya mphamvu yokhazikika. Ma capacitor a filimu opangidwa ndi zitsulo nthawi zambiri amakhala ndi mphamvu yokhazikika kwambiri ndipo amatha kugwira ntchito mokhazikika m'malo ovuta kwambiri. Mosiyana ndi zimenezi, ma capacitor a electrolytic a aluminiyamu ali ndi mphamvu yokhazikika yochepa, zomwe zimachepetsa kugwiritsidwa ntchito kwawo m'magwiritsidwe ena amphamvu kwambiri. Chifukwa chake, ma capacitor a filimu opangidwa ndi zitsulo ndi oyenera kwambiri machitidwe oyendetsa magalimoto omwe ali ndi mphamvu yowonjezereka komanso kukhazikika kwakukulu.
Malangizo a 03 YMIN osankha capacitor ya filimu yachitsulo
Ma capacitor a filimu a MAP ndi MDP omwe adayambitsidwa ndiYMINZipangizo zamagetsi zimapangidwa mwapadera kuti zigwiritsidwe ntchito bwino pamakina oyendetsa magalimoto kuti zikwaniritse zosowa zosiyanasiyana zovuta zogwirira ntchito.

04 Chidule
Pamene ukadaulo wamagalimoto ukupita patsogolo kuti ugwire bwino ntchito, kusunga mphamvu ndi nzeru, kukonza magwiridwe antchito komanso kudalirika kwa ntchito kwakhala cholinga chachikulu. Ma capacitor amafilimu achitsulo amagwira ntchito yofunika kwambiri mumakina oyendetsa magalimoto chifukwa cha magwiridwe antchito awo abwino kwambiri.YMINMa capacitor a mafilimu a MAP series ndi MDP series, omwe ali ndi mphamvu yolimba kwambiri, ESR yochepa komanso moyo wautali, amapereka njira zabwino zogwiritsira ntchito zida zamagalimoto m'mafakitale ndi ogula. M'tsogolomu, ndi chitukuko chachangu cha ukadaulo watsopano wamagetsi komanso kupanga mwanzeru, ma capacitor amafilimu achitsulo adzapititsa patsogolo magwiridwe antchito awo kuti akwaniritse kuchuluka kwa mphamvu zamagetsi, moyo wautali komanso kugwiritsa ntchito mphamvu zochepa, kuthandiza makina oyendetsa magalimoto kupita kumlingo wapamwamba.
