Downhole motor is composed of five assemblies: by-pass valve, motor, anti-drop, cardan shaft and drive shaft.
Downhole motor is a kind of downhole dynamic drilling tool upon the power of drilling mud. Mud stream from the
outlet of mud pup flows through a by-pass valve into the motor. This stream produces pressure loss at both inlet and
outlet of the pump to push the rotor into ratating, and to transmit the torque and speed onto the bit. The downhole
motor property mainly depends upon its property parameters.

Main Features
Controlled by built-in overlapped or parallel-connected electromagnetic precursor valve, with advanced craft and reliable action;
Diaphragm of main valve adopts imported special rubber, with high anti-corrosion and resisting low temperature at -40° C;
Special stainless steel magnetic material never rust or generate remanent magnetism;
Close the main valve when the working pressure is 0.3-0.4MPa, and the small flow system will be 3-3.5L/min, which can be designed according to users' requirements.
