20.4:1 Metal Gearmotor 25Dx65L mm HP 6V with 48 CPR Encoder
This gearmotor consists of a high-power, 6 V brushed DC motor combined with a 20.4:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 979.62 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.

3D models of 25D mm gearmotors (10MB zip)
This file contains 3D models (in the step file format) of the 25D mm gearmotors with and without encoders.
Note: This is not an easy modification, and the chassis can be damaged if it is not done properly, so we generally recommend against it, and we can only provide very limited support for those who want to attempt it. The manufacturer did not intend for the chassis to be modified in this way, and we do not know how well such a modification will work out.
