3D model of 15.5D mm gearmotors (2MB step)
3D model of the 15.5D mm gearmotors; this model applies to both 35:1 and 115:1 versions since they both have the same dimensions.
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.
