Tamiya’s twin-motor gearbox consists of two independent brushed DC motors and gearboxes in one compact housing, making it perfect for small robots. You can assemble the gearboxes to have a 58:1 or a 204:1 gear ratio.

General specifications

Typical operating voltage: 3 V
Gear ratio options: 58, 204 :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
Color: gray


A theoretical speed of the gearbox output shaft can be computed by dividing this speed by the gear ratio.
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.
A theoretical torque of the gearbox output shaft can be computed by multiplying this torque by the gear ratio.
