The primary feature of the Tamiya 72004 Worm Gearbox from Tamiya’s high-efficiency series is a worm gear, which locks the output shaft whenever the motor isn’t turning. The high gear ratios of 216:1 or 336:1 make this gearbox appropriate for small walking robots, lifting mechanisms, and other applications where high torque is desired.

The low-voltage motors in the worm gearbox run on 3-6 volts and draw up to a few amps, making them perfect candidates for the Pololu low-voltage dual serial motor controller. The Pololu Orangutan LV-168 robot controller, which incorporates these low-voltage motor drivers, would be a great control center for a robot using these motors. 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.

This gearbox has a 4 mm, round output shaft, which works with the wheels that are compatible with Tamiya 4 mm, round shafts. Our 3 mm universal mounting hub also fits on the threaded end of the shaft, although it is not specifically intended to work with this type of shaft (the hub’s set screw could damage the thread on the shaft).

Note: The worm gearbox is a kit; assembly is required. To use the kit in robotics projects, you need to connect the motors to your own robot controller.

  1. Michael Morgan

    Up to the usual standard we have come to expect from Tamiya , this motor/gearbox is easy to assemble . It gives quite a wide spectrum of speeds , and is not too noisy . I have used these before on my model railways , and they are quite dependable . Given the standard size of the motor , it is easy to replace the motor with another of your choosing , but I haven’t needed to.

    Usual Tamiya high standard , this easy to assemble item is very handy for motorising my models where space is at a premium ; I use them in model trains .
