Servo motor ndi injini yomwe imayang'anira magwiridwe antchito amagetsi mu dongosolo la servo. Ndi chida chothandizira kufalitsa motere. Servo mota imatha kuyendetsa liwiro, kulondola kwa malo ndikolondola kwambiri, imatha kusintha chizindikiro chamagetsi mu makokedwe ndi liwiro loyendetsa chinthu chowongolera. Liwiro la Servo motor rotor limayang'aniridwa ndi chizindikiro cholowetsera, ndipo limatha kuyankha mwachangu, mu makina oyendetsa basi, ngati gawo lalikulu, ndipo imakhala ndi nthawi yaying'ono yamagetsi, yolumikizana kwambiri, yoyambira magetsi ndi mawonekedwe ena, chizindikiritso chamagetsi chitha kukhala amasandulika kukhala shaft yamagalimoto kusunthira kwamayendedwe kapena kuthamanga kwa ma angular. Itha kugawidwa mu DC servo motors ndi ac servo motors. Makhalidwe ake akulu ndikuti voliyumu yamagetsi ikakhala zero, palibe chochitika chosinthasintha, ndipo kuthamanga kumachepa ndikukula kwa makokedwe.

Ma mota a Servo amagwiritsidwa ntchito m'njira zingapo zowongolera, zomwe zimatha kusintha ma voliyumu olowetsera kukhala opangira ma shaft yamagalimoto ndikukoka zida zowongoleredwa kuti zikwaniritse cholinga chowongolera.

Pali ma DC ndi ac servo motors; Galimoto yoyambirira kwambiri ya servo ndi mota yayikulu ya dc, pakuwongolera kulondola sikokwanira, kugwiritsa ntchito mota wa DC kuchita servo motor. Makina apano a DC servo mota ndi yamagetsi yamagetsi otsika, ndipo kukopa kwake kumayang'aniridwa ndi zida zamagetsi ndi maginito, koma nthawi zambiri kuwongolera zida.

Gulu la magalimoto oyenda, DC servo mota pamakina amakwaniritsa zofunikira za kayendetsedwe kake, koma chifukwa cha kukhalapo kwa commutator, pali zoperewera zambiri: commutator ndi burashi pakati pazosavuta kutulutsa ma sparks, ntchito yosokoneza woyendetsa, sangathe kugwiritsidwa ntchito ngati pali mpweya woyaka; Pali mkangano pakati pa burashi ndi woyendetsa, zomwe zimapangitsa malo akulu akufa.

Kapangidwe kake ndi kovuta komanso kukonza kumakhala kovuta.

Ac servo motor kwenikweni ndi magawo awiri osakanikirana, ndipo pali njira zitatu zowongolera: matalikidwe owongolera, kuwongolera magawo ndi kuwongolera matalikidwe.

Mwambiri, servo mota imafuna kuti liwiro lamagalimoto lizilamulidwa ndi siginecha wamagetsi; Liwiro lozungulira limatha kusintha mosalekeza ndikusintha kwamagetsi. Kuyankha kwa mota kuyenera kukhala kofulumira, voliyumu iyenera kukhala yaying'ono, mphamvu yoyang'anira iyenera kukhala yaying'ono. Ma motors a Servo amagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zoyendetsera mayendedwe, makamaka ma servo system.
