227:1 Metal Gearmotor 25Dx71L mm LP 12V with 48 CPR Encoder
This gearmotor consists of a low-power, 12 V brushed DC motor combined with a 226.76:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 10,884.47 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. This gearmotor is also available without an encoder.

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
- This is a theoretical value; stalling the gearbox output shaft is likely to damage the gearbox.
- 3
- This motor will run at 6 V but is intended for operation at 12 V.
- 4
- May vary by a few inches.
