Abstract: A device disclosed herein is used with an electric submersible pump (ESP) assembly disposed on tubing in a well. A housing of the device connects between tubing and pump. A shaft in the housing can rotate in response to imparted rotation associated with the pump and permanent magnet (PM) motor. A piston in the housing can move longitudinally relative to the shaft in response to a pressure differential across the piston. A clutch on the piston can engage and disengage with a distal end of the shaft in response to the piston's movement of the piston. Additionally or alternatively, a key on the piston can engage and disengage with a pocket on the shaft. The engagement of the clutch and/or key can prevent imparted rotation associated with the pump and the PM motor.
