300 RPM Square Gear DC Motor for Arduino / Raspberry-Pi / Robotics

This is Squared gear box assembled High torque heavy duty DC Gear Motor for bigger robots / motion systems. Drive shaft is supported from with metal bushes, it has sturdy design with gear box made to hold stall torque produced.It is suitable for combat robots, all-terrain robots and other high power applications

Working of Square Gear Box:

The working of the gears is very interesting to know. It can be explained by the principle of conservation of angular momentum. The gear having smaller radius will cover more RPM than the one with larger radius. However, the larger gear will give more torque to the smaller gear than vice versa. The comparison of angular velocity between input gear (the one that transfers energy) to output gear gives the gear ratio. When multiple gears are connected together, conservation of energy is also followed. The direction in which the other gear rotates is always the opposite of the gear adjacent to it. In any DC motor, RPM and torque are inversely proportional. Hence the gear having more torque will provide a lesser RPM and converse.

SPECIFICATION:

  • RPM: 300 rpm @12V
  • Voltage: 4V to 12V
