The N20 Gear Motor is a miniature high-performance DC motor paired with a precision metal reduction gearbox. This 6V 200RPM variant is a popular choice for micro-robotics, providing a "high-speed" output compared to the standard 100RPM models while still maintaining enough torque for mobile platforms. It features a 10mm D-shaped shaft, ensuring compatibility with a wide range of hobbyist wheels and couplers.

Specifications

• Rated Voltage: 6V DC (Operating range: 3V – 9V).
• No-Load Speed: 200 RPM (at 6V).
• Shaft Type: D-shape (flat side for secure, non-slip mounting).
• Shaft Diameter: 3mm.
• Shaft Length: 10mm.
• Gearbox Material: All-metal (Precision brass and steel gears).
• No-Load Current: ~ 40mA.
• Stall Current: ~ 550mA (at 6V).
• Stall Torque: ~ 0.6 kgcm to 0.8 kgcm.

Features

• Optimized Speed: The 200 RPM rating provides a brisk pace for small-wheeled robots, making it ideal for line followers and micro-rovers that require agility.
• Durable Metal Train: The all-metal gearbox is significantly more robust than plastic alternatives, resisting gear stripping and providing a longer service life under varying loads.
• Standardized 10mm Shaft: The extended D-shaft offers plenty of surface area for set screws to bite into, preventing wheels from spinning freely on the axis.
• Compact Integration: The rectangular form factor is a global standard for N20 motors, allowing for easy mounting in tight spaces or specialized 3D-printed chassis.

Pin and Connection Guide

• Terminals: Two solder tabs at the rear.
• Reversibility: The motor is bidirectional. Swapping the VCC and GND wires will reverse the rotation direction.
• Control Compatibility: Works seamlessly with common motor drivers like the L298N, TB6612FNG, or DRV8833 for PWM-based speed control.

Common Applications

• Micro-Robotics: Excellent for fast-moving line followers, "ant-weight" combat robots, and small 4WD rovers.
• Automated Mechanisms: Powering rapid-acting latches in smart locks or small component sorters.
• Precision Toys: Motorizing small-scale vehicles or animated scenery in model dioramas.
• Camera Equipment: Driving small-scale motorized sliders or pan-tilt heads for lightweight sensors.

Usage Tips

• Mounting: Always use a dedicated N20 bracket. Avoid applying mechanical pressure directly to the gearbox housing to ensure the internal gears remain aligned.
• Voltage Limit: While the motor can handle up to 9V for increased speed, 6V is the recommended operating voltage for the best balance of performance and motor longevity.
• Wiring Protection: The rear tabs are delicate. Use 26AWG–30AWG flexible wire and apply heat-shrink tubing to the soldered joints for strain relief.
• Gear Care: The gears are pre-lubricated; however, if the motor is used in a dusty environment, consider a protective enclosure to prevent debris from entering the gear train.
