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.
