This versatile, high-efficiency gearbox lets you build
one of the following gear ratios: 11.6:1, 29.8:1, 76.5:1, 196.7:1, 505.9:1, and
1300.9:1. Whatever your application, chances are that one of the configurations
will do the job. A clutch gear protects the gearbox in high-gear-ratio
configurations so that the gearbox doesn't rip itself apart if the output shaft
The motor is rated for 3 volts but will typically work
fine up to 6 volts. When using this product with the dual serial motor
controller (or any motor driver based on an H-bridge), keep in mind that up to a
few volts (depending on the load) are lost on the transistors of the H-bridge,
so that a 4.5 volt battery delivers about 3 volts to the motors, giving them a
reasonble amount of power. 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 5mm, round output shaft is compatible only with
Tamiya's sports tire set and narrow
|Note: The 6-speed 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.
