Pololu Tamiya 72002 High-Speed Gearbox Kit

The Tamiya 72002 high-speed gearbox offers versatility with its ability to be assembled in two different gear ratios: 11.6:1 and 18:1. This high-efficiency gearbox is ideal for fast-moving vehicles or mechanisms where high torque is not a necessity.

Perfect for projects requiring speed, this gearbox is a great choice for building rapid vehicles or other dynamic mechanisms. The low-voltage motors operate efficiently between 1.5 and 4.5 volts, drawing only a few amps, making them compatible with various motor drivers. It's important to monitor for overheating due to stalling, so implementing stall-detection sensors or keeping an eye on your robot is recommended to prevent prolonged stalling.

The gearbox features a 4 mm diameter round output shaft, compatible with wheels designed for Tamiya's 4 mm round shafts. Additionally, the 3 mm universal mounting hub can be used on the smaller threaded end of the shaft, though caution is advised as the hub's set screw might damage the thread.

For detailed motor specifications, refer to the Mabuchi motor RE-260 data sheet. To explore the range of Tamiya gearbox kits and their gear ratios, consult the Tamiya Gearbox Gear Ratio Comparison guide.

Note: This high-speed gearbox is a kit and requires assembly. To integrate it into robotics projects, connecting the motors to a robot controller is necessary.
