Abstract
A catch assembly is provided for a downhole motor assembly of a drilling system. The catch assembly may include a catch basket that may be coupled to a saver sub. The saver sub may be coupled to a stator tube housing a rotor of a downhole motor. The rotor knob may be coupled to the rotor and include a flange that may be positioned in the catch basket. The flange may be positioned uphole of an internal shoulder of the catch basket. Subsequent to a connection failure in or near the stator tube, the flange may engage the internal shoulder of the catch basket to prevent the rotor from falling downhole.
