Tamiya’s double gearbox packs two independent gear trains into a compact and affordable package that is great for small mobile robots. Each side can be assembled to have one of four gear ratios: 12.7:1, 38:1, 115:1, or 344:1.

General specifications

Typical operating voltage: 3 V
Gear ratio options: 12.7, 38, 115, 344 :1
Free-run motor shaft speed @ 3V: 12300 rpm1
Free-run current @ 3V: 150 mA2
Stall current @ 3V: 2100 mA
Motor shaft stall torque @ 3V: 0.5 oz·in3

Notes:

1
A theoretical speed of the gearbox output shaft can be computed by dividing this speed by the gear ratio.
2
This is the no-load current of the motor when disconnected from the gears in the gearbox; the no-load current of the entire gearbox with the motor connected will be slightly higher and will vary depending on the gear ratio.
3
A theoretical torque of the gearbox output shaft can be computed by multiplying this torque by the gear ratio.
