The uniform wall thickness down-hole motor changes the shape of the stator shell to make the stator rubber thin and uniform in order to overcome the conventional technology of drill stator and effectively improve the working environment of down-hole motor. The structure enhances the motor's lifetime. Compared with the conventional down-hole motor, the ordinary has rubber bushings of uneven thickness, the motor will easily lead to failure, thus shortening the life of the motor, uniform wall thickness down-hole motor has short pump, small torque. This type of down-hole motor has the following advantages: Thermal efficiency, rubber swelling, even thermal expansion, used in a wider range, more optimized structure, and lighter quality. At present our company produces such as wall thickness down-hole motor with the pressure drop and torque 3 - 3.5 times as the ordinary motor. At the same time, in the same mine, at the same footage, the new down-hole motor can drill faster **2 times and has use lifetime **2 times as the ordinary motors, savings cost about *0%.
