The Endura® Pro motor features a constant torque 48 frame ECM that serves as a smart alternative to the original X13® motor. This motor's high moisture design is a direct drop-in replacement for the X13 motor with enhanced moisture robustness beyond that of X13. All applications featuring the X13 motor will now use the Endura Pro motor.
