This 143:1 gear motor spins at 70RPM at 5V, drawing 670mA at stall generating 43 in*oz torque (free running at 57.6mA).
With a 7mm double-flat output shaft (avoid using the green double flat output - it's not meant to take rotational load), and a built-in clutch and built-in mounting screw holes, you can see why we like these motors!
