The High Power Gear Box, High Efficiency, works well when extra torque is necessary. It can be built in a gear ratio of 41.7:1 or 64.8:1, making it well-suited for most vehicles that require a balance of speed and torque. A RE-260 motor is included. Several types of crank arms are included for extra flexibility in design.
The low-voltage motors in the high-power gearbox run on 3-6 volts and draw up to a few amps, making them perfect candidates for the low-voltage motor controller.
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.
