Servo mota ndi galimoto yozungulira yomwe imatha kuwongolera mchitidwe wowongolera momwe angagwiritsire ntchito munthawi ya servo. Galimoto iyi yomwe imalola kuwongolera kolondola malinga ndi malo angular, mathamangitsidwe ndi velocity, kuthekera komwe galimoto yokhazikika ilibe.

Ntchito yayikulu ya servo drive ndi yomwe imalandira chizindikiro kuchokera ku khadi la NC, kukonza chizindikirocho ndikupereka mota ndi masensa omwe akukhudzana ndi mota, ndikuwonetsa momwe wolamulira wamkulu.

Kukula kumatha kuwakundikira mphamvu kapena mphamvu ya chizindikiro. Ili ndi chubu kapena transistor, wosinthitsa mphamvu, ndi zinthu zina zamagetsi.

Inverter ndi zida zamagetsi zowongolera zomwe zingasinthe zomwe zimapangitsa kuti magalimoto azitha kuyendetsa ac servo. Olowetsa makamaka amakhala ndi okonzanso (AC kupita ku DC), infperwer (DC ku AC), DC ya ma brake, yoyendetsa unit, yokonzanso gawo limodzi.

Woyang'anira mapulogalamu a PLC (PLC) kapena wowongolera mapulogalamu ndi digito ya zamagetsi zamagetsi, zomwe zidapangidwa kuti zizigwiritsa ntchito mafakitale. Itha kugwiritsa ntchito kukumbukira kukumbukira kwa mkati, komwe kumagwiritsidwa ntchito posungira malangizowo pochita ntchito monga magwiridwe antchito, nthawi zonse zowerengera, komanso njira zopangira ma udalog.

Bungwe la madera likhoza kupanga zozungulira komanso zowoneka bwino, zomwe zimachita mbali yofunika kwambiri yopanga madera okhazikika komanso kukhathamiritsa m'magetsi. Ndipo bolodi la maderanso imatha kutchedwa (gulu la madera osindikizidwa) PCB ndi (bolodi yosinthika) FPC. Pali zinthu zina zabwino, monga kachulukidwe kakang'ono, kulemera kopepuka, makulidwe ndi kugwada bwino ndi zina zotero.
