The Rotor Catch is a tool used in down-hole Drilling Motors to assure the extraction of the Rotor. On rare occasions, motors, mainly the power section, have parted below the Stator. When this occurs generally the stator comes out of the hole leaving the Rotor facing up hole and resulting in a fishing job over an uneven surface.
