Downhole Motors - Positive Displacement Motors : Characteristics

Characteristics
• Torque is directly proportional to the motor’s differential pressure.
This makes the tool a very simple to operate.
• RPM is directly proportional to flow rate, through somewhat affected
by torque output.
• Hydraulic horsepower consumed = {(P x Q) ¸ 1714}, where P is the
pressure drop (psi) across the motor and Q is flow rate (gpm).
