3mm Shaft Gearmotors

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. Versions are also available with an optional extended motor shaft.

All of these Tamiya gearboxes have 3mm hexagonal shafts.
