N20 Gear Motor 300RPM – Micro Metal Geared DC Motor

The N20 Gear Motor 300RPM is a compact, high-torque micro metal gear motor designed for precision motion control in small robotics, automation, and DIY electronics projects. Featuring a full-metal gearbox and a D-shaped output shaft, it delivers a reliable no-load speed of 300 RPM with efficient torque output, making it a popular choice for space-constrained mechanical designs.

Key Features

• Rated no-load speed of 300 RPM
• All-metal gearbox for durability and smooth operation
• D-type output shaft for secure wheel and coupling attachment
• Compact 12mm diameter cylindrical motor body
• Operates across a wide 6V to 12V voltage range
• Low no-load current draw for efficient operation
• Lightweight design suitable for small mobile platforms
• Threaded M3 mounting holes for secure installation
• Easy integration with Arduino, ESP32, and motor driver modules

Technical Specifications

Applications

• Robotic Drive Systems
• Small Robot Cars and Wheeled Platforms
• Linear Actuators and Motion Mechanisms
• DIY Automation and Mechatronics Projects
• Lock Systems and Small Gearboxes
• Model Vehicles and Educational Kits
• Space-Constrained Custom Designs

Important Notes

• Do not exceed the rated 12V supply voltage; higher voltages will increase speed but generate excess heat.
• Avoid prolonged stall conditions as stall current is significantly higher than rated running current.
• Use a suitable motor driver module (such as L298N or MX1508) rather than powering directly from a microcontroller pin.
• Actual RPM and torque may vary slightly with load, supply voltage, and manufacturing tolerances.
• Handle the D-shaped shaft carefully to avoid damaging the gearbox during wheel or coupler installation.
• Mount securely using the provided M3 screw holes to reduce vibration and mechanical stress.
