Mud motor (or Drilling Motor) refers to a Progressive Cavity Positive Displacement Pump placed in the Drill string to provide additional power to the bit while drilling. The PCPD Pump uses Drilling Fluid (commonly referred to as Drilling Mud, or just Mud) to create eccentric motion in the power section of the motor which is transferred as concentric power to the drill bit (well). The Mud Motor uses different rotor and stator configurations to provide optimum performance for the desired drilling operation, typically increasing the number of lobes and length of power assembly for greater horsepower. In certain applications, compressed air, or other gas, can be used for Mud Motor input power. Normal rotation of the bit while using a Mud Motor can be from 60 rpm, to over 100 rpm.

Famous quotes containing the words mud and/or motor:
“The swimming hole is still in use. It has the same mudbank. It is still impossible to dress without carrying mud home in one’s inner garments. As an engineer I could devise improvements for that swimming hole. But I doubt if the decrease in mother’s grief at the homecoming of muddy boys would compensate the inherent joys of getting muddy.”
—Herbert Hoover (1874–1964)
“The motor idles.
Over the immense upland
the pulse of their blossoming
thunders through us.”
—Denise Levertov (b. 1923)
