47:1 METAL GEARMOTOR 25DX67L MM LP 6V WITH 48 CPR ENCODER
47:1 METAL GEARMOTOR 25DX67L MM LP 6V WITH 48 CPR ENCODER
This gearmotor consists of a low-power, 6 V brushed DC motor combined with a 46.85:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 2248.86 counts per revolution of the gearbox’s output shaft. The gearmotor is cylindrical, with a diameter just under 25 mm, and the D-shaped output shaft is 4 mm in diameter and extends 12.5 mm from the face plate of the gearbox.

Notes:
1 Length measurement is from gearbox face plate to back of encoder cap (it does not include the output shaft). See dimension diagram for details.
2 D shaft.
3 Typical; ±20%.
4 Typical, ±50%; no-load current depends on internal friction, which is affected by many factors, including ambient temperature and duration of motor operation.
5 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.
6 May vary by a few inches.
