BR772005 15.11

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 gets stuck.

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 tire set.

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. Motor is RE260 3V (Max 4.5V)/1A, 10500 RPM. Click here to compare these gearboxes.
