Original sentence: 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.Normal Mud Motor construction consists of a top sub, which connects the Mud Motor to the Drill String; the Power Section, which consists of the Rotor and Stator; the Transmission Section, where the eccentric power from the rotor is trasmitted as concentric power to the bit; the Bearing Assembly which protects the tool from off bottom and on bottom pressures; and the bottom sub which connects the Mud Motor to the bit
