34:1 Metal Gearmotor 25Dx52L mm MP 12V
This gearmotor consists of a medium-power, 12 V brushed DC motor combined with a 34.014:1 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.

- MATLAB script to plot motor performance curves for Pololu brushed DC gearmotors
- This MATLAB script, written by Ali Asgher Mansoor Habiby, plots speed, power, current draw, and efficiency as they vary with torque when you input the gearmotor specifications. It also prints the resistance of the motor, and the current draw and torque at which maximum efficiency and maximum power occur.
