131:1 METAL GEARMOTOR 37DX73L MM 12V WITH 64 CPR ENCODER (SPUR PINION)
131:1 METAL GEARMOTOR 37DX73L MM 12V WITH 64 CPR ENCODER (SPUR PINION)
This gearmotor is a powerful 12V brushed DC motor with a 131.25:1 metal gearbox and an integrated quadrature encoder that provides a resolution of 64 counts per revolution of the motor shaft, which corresponds to 8400 counts per revolution of the gearbox’s output shaft. These units have a 16 mm-long, 6 mm-diameter D-shaped output shaft.

2 D shaft.
3 Stalling is likely to damage the gearmotor. Stall parameters come from a theoretical extrapolation of performance at loads far from stall. As the motor heats up, as happens as it approaches an actual stall, the stall torque and current decrease.
4 This motor will run at 6 V but is intended for operation at 12 V.
5 Stalling is likely to damage the gearmotor. Stall parameters come from a theoretical extrapolation of performance at loads far from stall. This motor will run at 6 V but is intended for operation at 12 V.
6 May vary by a few centimeters.
