The primary feature of this high-efficiency gear box 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 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 reasonable 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 worm-gear 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/FA130, 3V (Max 4.5V)/0.5A, 10500 RPM. Click here to compare these gearboxes.
