N20 Micro DC Gear Motor 300RPM 12V

Overview 

The N20 300RPM Gear Motor is a high-precision, sub-miniature motor designed for high-end hobbyist and industrial applications. While most cheap toy motors use plastic gears that strip under pressure, the N20 uses a full-metal geartrain to ensure longevity and consistent torque. The 300RPM variant is the “sweet spot”—it provides a great balance of speed for micro-vehicles and enough torque ($0.5 \text{ to } 2.0 \, kg\cdot cm$ depending on load) to move substantial weight.

Key Features 

• Ultra-Compact: One of the smallest gear motors available; fits easily into handheld devices and micro-robot chassis.

• All-Metal Gearbox: Precision-cut gears provide superior durability and wear resistance compared to plastic.

• Long D-Shaft: The 3mm D-shaped output shaft prevents wheels or gears from slipping, even under high stall conditions.

• Versatile Voltage: While rated for 12V, it runs smoothly anywhere from 3V to 12V, allowing you to trade speed for torque.

• Precision Control: Very low backlash makes it ideal for projects requiring fine-tuned positioning.
