47:1 Metal Gearmotor 25Dx52L mm HP 12V
This gearmotor consists of a high-power, 12 V brushed DC motor combined with a 46.85:1 metal spur gearbox. 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. This gearmotor is also available with an integrated encoder.

Notes:
- 1
- Length measurement is from gearbox face plate to back of motor (it does not include the output shaft or motor terminals). 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
- This motor will run at 6 V but is intended for operation at 12 V.
