700:1 Sub-Micro Plastic Planetary Gearmotor 6Dx21L mm
This tiny, cylindrical gearmotor consists of a coreless brushed DC motor and a 700:1 plastic planetary gearbox. The entire assembly has a diameter of just 6 mm (0.24″) and an extremely light weight of 1.3 g (0.046 oz), making it a great actuator for miniature robots and very small mechanisms.
Key specs at 6 V: 90 RPM and 45 mA free-run, 12 oz-in (0.9 kg-cm) and 400 mA stall.
Alternatives available with variations in these parameter(s): gear ratio Select variant…

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.
