Tamiya 72001 Planetary Gearbox Kit
 
|
The first in Tamiya’s “high efficiency” series, the planetary gearbox features two 4:1 and two 5:1 stages that can be combined in any way you like—you can even combine two kits to get really huge gear ratios. The output is always conveniently on the same axis as the motor shaft. Available gear ratios are 4:1, 5:1, 16:1, 20:1, 25:1, 80:1, 100:1, and 400:1.

The low-voltage motors in the planetary 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.
The 4mm, round output shaft on this gearbox is compatible only with Tamiya’s sports tire set and narrow tire set.
For motor specs, see the Mabuchi motor RC-260 (#2295) data sheet (60k pdf). To compare all Tamiya gear box kits, see the Tamiya Gearbox Gear Ratio Comparison.
Note: The planetary 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.
