With a cross section measuring only 10×12 mm, these small brushed DC gearmotors are available in a wide range of gear ratios—from 5:1 up to 1000:1—and with four different motors: high-power with long-life carbon brushes (HPCB), high-power (HP), medium-power (MP), and low-power. Some versions are also available with an optional extended motor shaft.

These 20 mm-diameter (0.79″-diameter) gearmotors offer a lot of power for their size. The are available in several different gear ratios, from 29:1 to 154:1.

These 25 mm-diameter (0.98″) gearmotors, spanning a range of gear ratios from 4.4:1 to 499:1, offer a good combination of power and compactness. We have high- and low-current versions to choose from, and integrated 48 CPR encoders are available with selected gear ratios.

Measuring 37 mm (1.46″) in diameter, these 12 V motors are the largest and most powerful gearmotors we carry. They are available in a range of gear ratios from 19:1 to 131:1. An integrated 64 CPR encoder is an option for all of these motors.
