I-downhole Motor luhlobo lwesixhobo samandla somngxuma osezantsi esithatha amandla kulwelo size siguqulele uxinzelelo lolwelo kumandla oomatshini. Xa umbane wamandla ugeleza kwi-motor hydraulic, umahluko woxinzelelo owakhiwe phakathi kokungena kunye nokuphuma kwemoto unokujikeleza i-rotor ngaphakathi kwe-stator, ukubonelela nge-torque eyimfuneko kunye nesantya kwi-drill bit for drilling. Isixhobo se-screw drill sifanelekile kwimithombo ethe nkqo, eyalathiso kunye nethe tye.
