Subcategories

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.

All of these Tamiya gearboxes have 3mm hexagonal shafts.

These compact and inexpensive brushed DC gearmotors are available in several different orientations, gear ratios, and power levels. Some versions are also available with an optional extended motor shaft.
