Akutumizandi gawo lamagetsi lomwe limagwiritsa ntchito mfundo za ma elekitiromagineti kapena zinthu zina zakuthupi kuti akwaniritse "kudzimitsa / kuzimitsa" kwa mabwalo. Ntchito yake yayikulu ndikuwongolera mabwalo akuluakulu amakono / okwera ma voltage okhala ndi ma siginecha ang'onoang'ono / ma sign, ndikukwaniritsanso kudzipatula kwamagetsi pakati pa mabwalo kuti atsimikizire chitetezo chakumapeto kowongolera.

Ntchito zake zazikulu zitha kugawidwa m'magulu atatu:

1. Kulamulira ndi Kukulitsa: Ikhoza kusintha zizindikiro zofooka zowongolera (monga milliampere-level currents zotuluka ndi single-chip microcomputers ndi masensa) kukhala mafunde amphamvu okwanira kuyendetsa zipangizo zamakono (monga motors ndi heaters), kugwira ntchito ngati "signal amplifier". Mwachitsanzo, m'nyumba zanzeru, timagetsi tating'onoting'ono totumizidwa ndi mapulogalamu amafoni a m'manja titha kuwongoleredwa ndi ma ralay kuti azimitsa ndi kuzimitsa mphamvu yamagetsi am'nyumba ndi nyale.

2. Kudzipatula kwamagetsi: Palibe kugwirizana kwa magetsi kwachindunji pakati pa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake Malangizo owongolera amangoperekedwa kudzera pa maginito amagetsi kapena ma siginecha owoneka kuti ateteze ma voliyumu apamwamba kuti asalowe mu terminal ndikuwononga zida kapena kuyika chitetezo cha ogwira ntchito pachiwopsezo. Izi nthawi zambiri zimapezeka m'mabwalo owongolera a zida zamakina zamakina ndi zida zamagetsi.

3. Mfundo ndi Chitetezo: Zingaphatikizidwe kuti zigwiritse ntchito zovuta zowonongeka, monga kutsekereza (kuletsa ma motors awiri kuyambira nthawi imodzi) ndi kuchepetsa kulamulira (kuchedwa kugwirizanitsa katundu kwa nthawi inayake pambuyo pa mphamvu). Ma relay ena odzipatulira (monga ma relay opitilira muyeso ndi ma relay otenthetsera) amathanso kuyang'anira zolakwika zadera. Kutentha kukakhala kokulirapo kapena kutentha kwambiri, amangodula dera kuti ateteze zida zamagetsi kuti zisawonongeke.
