The Tamiya 4-speed crank-axle gearbox has four possible gear ratios,
including the highest gear ratio of Tamiya's gearbox series, 5402:1,
as well as 126:1, 441:1, and 1543:1.
This gearbox also features a worm gear, which locks the output shaft
when the motor is not turning. A clutch gear prevents the gearbox from
destroying itself in case the output shaft gets stuck. The kit comes
with all parts necessary to build the gearbox in any of the four
The output shafts are 3 mm hexagonal axles that are 10 cm (about four
inches) from tip to tip. The axles work with any of the Tamiya wheels,
giving you many options for your robot speed.
The low-voltage motors run on 3-6 volts and draw up to a few amps,
making them perfect candidates for the DRV8833 motor driver carrier.
Motor overheating can be caused by excessive stalling, even at very
low voltages. We recommend that you use stall-detection sensors, or
just watch your robot, to make sure that it doesn't stall for more
than a few seconds at a time. For motor specs, see the Mabuchi motor
FA-130 data sheet.
Note: The universal gearbox kit is a kit; assembly is required. To use
the kit in robotics projects, you need to connect the motors to your
own robot controller.…more
