Abstract
A rotor catch system includes a catch stem having a proximal end coupled to a rotor of a mud motor system and a distal end positioned within a sub housing of a drill string, a catch feature having a top portion and a spindle portion extending from the top portion and coupled to the distal end of the catch stem, a housing catch feature extending radially inward from an inner surface of the sub housing, and a catch bushing positioned between the top portion of the catch feature and the housing catch feature. The housing catch feature restrains axial movement of the catch bushing in the active catch state via contact between the catch bushing and the housing catch feature, and the catch bushing restrains axial movement of the catch feature in the active catch state via contact between the catch feature and the catch bushing.
