SKU: ROB-117 Manufacturer: Tamiya Mfg Part Number: 70097



The Tamiya twin-motor gearbox is a small (3-inch long) plastic gearbox. It contains two small brushed DC motors that drive separate 3mm hexagonal output shafts. There are two ways to put the kit together: with a high-speed 58:1 gear ratio or with a slower 203:1 gear ratio. Either way, the motors provide plenty of power to drive any small robot.

The output shafts included in this kit are 3 mm hexagonal axles that are 10 cm (about four inches) from tip to tip. The two low-voltage motors run on 3-6 volts and draw up to a few amps, making them perfect candidates for the DRV8833 Motor Driver breakout, Dual Motor Driver for Arduino, or the Dual Motor Driver for Raspberry Pi.


  • Gear Ratios: 58, 204:1
  • Free-run motor shaft speed @ 3V: 12300 rpm
  • Free-run current @ 3V: 150mA
  • Typical operating voltage: 3V
  • Stall current @ 3V: 2100mA
  • Motor shaft stall torque @ 3V: 0.5 oz·in
