Motor assembly and parts consist of stator and rotor. Stator is made by squeezing rubber sleeve on the wall of the steel tube. There forms spiral structure with a  certain geometric parameter. Rotor is a crome-plated screw rod.

The basic principle of downhole motor goes like this: stator and rotor matches with each other, to form spiral line and seal cavity through their guide rail difference. With rotor running in the stator, the seal cavity is moving along its axial direction, continuously forms and disappears to complete its energy conversion.
