Mphamvu yamagetsi ndi kutentha ziyenera kukhala ndi chotenthetsera. Chotenthetsera nthawi zambiri chimalumikizidwa ku shaft yayikulu yomweyi ndi jenereta. Pamene shaft yayikulu ikuzungulira pansi pa drive ya prime mover, nthawi yomweyo imayendetsa jenereta ndi chotenthetsera kuti zizungulire. Chotenthetsera ndi jenereta ya DC yomwe imatulutsa mphamvu ya DC, yomwe imatumizidwa ku coil ya rotor kudzera mu slip ring ya rotor ya jenereta kuti ipange mphamvu ya maginito mu rotor, motero imapanga mphamvu yoyambitsidwa mu stator ya jenereta. Chotenthetsera cha seti yayikulu kwambiri ya jenereta chimasinthidwa ndi self-shunt AC excitation system, yomwe yambiri imagwiritsa ntchito voltage ya jenereta kuti idutse kusintha kwa excitation, kudutsa mu chipangizo chokonzanso kupita ku direct current, kenako kutumiza magetsi kudzera mu jenereta rotor slip ring. Dongosolo lamtunduwu likagwiritsidwa ntchito, chotenthetsera choyamba cha jenereta chiyenera kuchitika nthawi iliyonse ikayatsidwa, zomwe zikutanthauza kuwonjezera chotenthetsera choyamba ku jenereta kuti ikhazikitse voltage yoyamba ya jenereta.
Kutulutsa kwa exciter yakale kumadalira kubwezeretsanso kwake, komwe kungapangitse exciter kupanga magetsi, koma mphamvu yake ndi yochepa kwambiri ndipo magetsi ndi ofooka kwambiri, koma mphamvu yofooka iyi imadutsa mu coil yotulutsa ya exciter kuti ilimbikitse mphamvu ya remanence. Mphamvu yamaginito yolimbikitsidwayi imapitiliza kupangitsa exciter kupanga magetsi, omwe ndi mphamvu yochulukirapo kuposa kupanga mphamvu ya maginito yotsalira, kenako kubwereza izi mobwerezabwereza, magetsi otulutsidwa ndi exciter amatha kukwera kwambiri, ndiko kuti, magetsi otulutsidwa ndi exciter ndi oyamba okha. Amagwiritsidwa ntchito kukhazikitsa mphamvu yakeyake, ndipo amapereka jenereta yokha pamene magetsi enaake okwera afika. Dongosolo lotulutsa la majenereta akuluakulu amakono limagwiritsa ntchito njira yotulutsira ma microcomputer, ndipo kuyambitsa kwake koyamba kumaperekedwa ndi magetsi oyamba otulutsira, omwe amaperekedwa ndi gridi yamagetsi kapena ndi magetsi a DC a chomera chamagetsi.
