Mud Motors
Mud motors are long, cylindrical, lobed motors which use fluid pressure to turn the drill bit. Mud motors
therefore require large drilling fluid flow rates to operate consistently and without cavitation.
Because mud motor requirements can exceed capabilities of starter rod, the mud motor may require direct
connection to drill string to fully utilize motor.
