Product Details :

Ultra-Fast Micro-Drive: Integrates a $6 ext{V}$ core with a micro low-ratio spur gearbox to deliver fast $600 ext{ RPM}$ rotation speeds where rapid movement is essential.
Durable All-Metal Gear Train: Built with high-precision steel and brass spur gears to ensure wear resistance, minimal backlash, and extended operating life under dynamic drive loads.
Precision D-Shaped Output Shaft: Uses a standardized $3 ext{mm}$ single-side D-shaft for non-slip coupling with mini wheels, timing pulleys, gears, and drive linkages.
Energy-Efficient Circuitry: Features exceptionally low no-load current draw ( $sim 40 ext{mA}$ ), making it ideal for battery-powered setups like 1S/2S LiPo battery systems and portable IoT hardware.
Wide Operating Voltage Range: Rated at $6 ext{V DC}$ , but operates smoothly down to $3 ext{V DC}$ for dynamic speed scaling through PWM motor driver boards.

How to Use

Solder your power wires to the small positive ( $+$ ) and negative ( $-$ ) terminals located at the back of the motor end-cap.
Push-fit or mount compatible robot wheels, couplers, or gears onto the $3 ext{mm}$ D-shaft.
Wire the motor leads to a suitable low-voltage motor driver module (e.g., DRV8833, TB6612FNG, or L298N).
Power your driver board with up to $6 ext{V DC}$ .
Modulate speed using PWM control signals and reverse direction by swapping pin polarities.

SAFETY NOTICE: Avoid running the motor under a continuously stalled load at full voltage ( $6 ext{V}$ ), as the full stall current ( $0.67 ext{A}$ ) can overheat the armature winding and strain the micro-gear train.
