Product Details :

Compact High-Speed Output: Combines a miniature $12 ext{V}$ DC core with a low-ratio precision all-metal gearbox to deliver rapid rotation speeds in tight mechanical enclosures.
Durable All-Metal Gear Train: Constructed with heavy-duty spur gears that resist surface wear, reduce rotational backlash, and maintain consistent output without tooth stripping.
Precision D-Shaped Output Shaft: Includes a standardized $3 ext{mm}$ D-shaft for slip-free attachment of wheels, timing pulleys, couplers, and small linkages.
Energy-Efficient Drive: Optimized for low electrical noise and power consumption, making it ideal for 3S LiPo battery systems, portable devices, and IoT hardware nodes.
Flexible Operating Range: Optimized for $12 ext{V DC}$ operation, but runs safely across $6 ext{V}$ to $12 ext{V DC}$ for dynamic speed adjustment via PWM motor controllers.

How to Use

Solder your positive ( $+$ ) and negative ( $-$ ) supply leads directly to the motor end-cap terminal pads.
Press-fit or set-screw compatible wheels or couplers onto the $3 ext{mm}$ D-shaft.
Wire the motor leads to a dual H-bridge driver module (such as TB6612FNG, L298N, or L293D).
Supply up to $12 ext{V DC}$ main power to your motor driver.
Adjust output rotation speed via PWM signals and flip rotation directions by toggling logic pin inputs.

SAFETY NOTICE: Avoid running the motor under a continuous locked-rotor stall condition at full $12 ext{V}$ input, as prolonged high currents can overheat the armature and degrade small gearbox teeth.
