Product Details :

Ultra-Compact High-Torque Powerhouse: Combines a miniature $12 ext{V}$ DC motor core with a multi-stage precision all-metal gearbox to deliver impressive torque output relative to its tiny footprint.
Durable All-Metal Gear Train: Heavy-duty steel and brass spur gears ensure superior wear resistance, low backlash, and long continuous operation without gear stripping.
Precision D-Shaped Output Shaft: Includes a standard $3 ext{mm}$ D-shaft for secure, slip-free mounting of wheels, pulleys, couplers, and mechanical levers.
Energy-Efficient Operation: Features low no-load current draw, making it highly suitable for battery-operated handheld devices, wireless robotics, and IoT nodes.
Versatile Power Input: Optimized for nominal $12 ext{V DC}$ operation, but operates safely between $6 ext{V}$ and $12 ext{V DC}$ for variable speed control using PWM motor drivers.

How to Use

Connect positive ( $+$ ) and negative ( $-$ ) supply wires to the solder tabs on the rear motor end-cap
Press-fit or set-screw attach compatible wheels or couplers onto the $3 ext{mm}$ D-shaft
Connect the motor leads to an H-bridge motor driver (such as L298N, L293D, or TB6612FNG)
Apply up to $12 ext{V DC}$ power supply to driver board
Adjust output speed via PWM signals and change rotation direction by swapping pin polarities

SAFETY NOTICE: Do not mechanically lock or stall the output shaft for extended periods while powered, as excessive stall current can strip tiny gear teeth or overheat the motor windings.
