Mud Motors (Cont’d)
Turbine motor
The turbine motor consists of:
A multistage blade-type rotor and stator sections. The number
of rotor/stator sections can vary from 25 to 50.
A thrust bearing section and a drive shaft.
The rotor blades are connected to the drive shaft and are
rotated by mud pumped under high pressure.
The stator deflects the mud onto the rotor blades.
Rotation of the rotor is transmitted to the drive shaft and drill
bit.
