N20 DC 6V Mini Metal Gear Motor

N20 DC 6V Mini Metal Gear Motor is an ultra-compact, high-torque precision micro actuator designed for miniaturized robotics, precision automation, and micro-mechatronic projects. Featuring a robust all-metal internal gearbox and a high-efficiency DC motor core, this tiny motor delivers exceptional mechanical torque and reliable speed reduction in a remarkably small footprint. It is the premier choice for micro line-following robots, miniature smart cars, electronic door locks, camera gimbals, and automated miniature mechanisms driven by microcontrollers.

Features

• Robust all-metal internal gear reduction train ensuring high durability, wear resistance, and long operating life
• Ultra-compact and lightweight miniature design ideal for space-constrained projects
• Wide operating voltage range (3V to 6V DC) providing adjustable speed and torque outputs
• Precision output D-shaft designed for secure press-fit mounting of 44mm 3PI/miniQ wheels or custom couplings
• High stall torque relative to size, enabling lifting or driving of small robotic payloads
• Low electrical noise and smooth rotational performance
• Seamless integration with microcontrollers (Arduino, ESP32, Raspberry Pi Pico) via micro motor drivers (e.g., TB6612FNG, DRV8833)
• Pre-soldered or easy-to-solder terminal pins for quick electrical connections

Applications

• High-speed miniature line-following, maze-solving, and sumo robots
• 3PI and miniQ style compact micro robot platforms
• Miniature automated mechanisms, electronic security locks, and optical focus gimbals
• Smart medical devices, miniature pumps, and precision valve actuators
• Polytechnic diploma, university engineering thesis, and advanced STEM micro-robotics projects

Important Notes:

• Driver Required: Never connect the motor directly to a microcontroller GPIO pin; always use an appropriate DC motor driver or H-bridge IC (such as DRV8833 or TB6612FNG) capable of handling startup surge currents.
• Avoid continuously stalling the motor shaft under voltage; prolonged stall conditions can overheat the motor windings or strip the metal gear teeth.
• Use appropriate heat control when soldering wires onto the motor terminals to avoid damaging the internal plastic end cap.
• Match the operating voltage to your torque/speed requirements (3V for lower speed/torque, 6V for maximum performance).
