12GA-N20 Miniature DC Metal Gear Motor — 3V / 3.7V / 5V / 6V / 12V

Miniature DC metal gear motor with low RPM, high torque output — engineered for 4WD micro cars, electric screwdrivers, door locks, robotics and compact DIY projects.

• Compact metal gearbox for durability and smooth operation
• Low RPM gear reduction for controlled motion and higher torque
• Wide voltage compatibility: 3V, 3.7V, 5V, 6V, 12V (choose model to match your power source)
• Ideal for tight spaces and precision small-mechanism applications

Key Features

• Metal gearhead: increased wear resistance and longer service life compared to plastic gears
• High torque at low speed: better load handling, precise actuation and reduced stalling
• Multiple voltage options: pick the operating voltage that fits your battery or power supply
• Stable performance for continuous use in hobbyist and light industrial applications

Benefits

• Reliable power for micro 4WD cars — improved traction and control
• Strong enough for handheld tools like mini electric screwdrivers and actuators
• Perfect for door lock mechanisms and small automated latches needing steady torque
• Great choice for robotics, automated model parts and DIY electronics projects

Typical Applications

• Miniature 4WD and RC cars

• Educational robots, servos substitutes, and small linear actuators
• Hobby projects, prototypes and light automation tasks

Installation & Tips

• Match motor voltage to your power source for optimal life and performance
• Use a proper motor driver or current-limited supply to prevent overheating and overcurrent
• Secure mounting and proper alignment minimizes noise and gear wear
• For speed control, use PWM motor drivers compatible with chosen voltage
• Add a diode or motor driver with flyback protection if switching with a transistor or microcontroller

What’s Included

• 1 x 12GA-N20 miniature DC metal gear motor (voltage/model as selected)
• Note: wiring, mounting hardware and connectors are not included unless specified
