The N20 Gear Motor is a high-performance miniature DC motor featuring a precision metal reduction gearbox. This 12V 200RPM variant is designed for applications requiring a balance of efficient speed and reliable torque at a higher voltage. It features a 10mm D-shaped shaft, ensuring a secure, non-slip interface for wheels, gears, and couplers.

Specifications

• Rated Voltage: 12V DC (Operating range: 6V – 14V).
• No-Load Speed: 200 RPM (at 12V).
• Shaft Type: D-shape (flat side for mechanical locking).
• Shaft Diameter: 3mm.
• Shaft Length: 10mm.
• Gearbox Material: All-metal (Precision brass and steel gears).
• No-Load Current: ~ 40mA.
• Stall Current: ~ 0.7A (at 12V).
• Stall Torque: ~ 0.8 kgcm to 1.2 kgcm.

Features

• Versatile Speed Profile: 200 RPM at 12V provides a brisk, controlled rotation suitable for mobile robots and automated machinery that needs to move with precision.
• Rugged All-Metal Gearing: The precision-cut metal gear train offers significantly higher durability and impact resistance than plastic alternatives, preventing gear stripping under load.
• Standard 10mm Shaft: The extended D-shaft provides a large surface area for set screws to bite into, ensuring that attachments stay locked during high-torque operation.
• Ultra-Compact Footprint: The tiny rectangular design allows for high-power integration in space-constrained projects like handheld devices or slim robotic chassis.

Pin and Connection Guide

• Terminals: Two solder tabs located at the rear of the motor housing.
• Bidirectional: The motor is fully reversible. Swapping the positive and negative power leads will change the rotation direction.
• Control: Compatible with standard motor drivers (e.g., L298N, TB6612FNG, or DRV8833) for PWM-based speed and direction control.

Common Applications

• Micro-Robotics: An excellent choice for 4WD micro-rovers, line followers, and small-scale balancing robots.
• Automated Security: Powering the locking mechanisms in 12V smart locks, safes, and cabinet latches.
• Precision Actuators: Driving internal shutters, valves, or small linear sliders in industrial equipment.
• Model Engineering: Providing realistic, high-torque movement for model cranes, elevators, or rotating radar dishes.

Usage Tips

• Mounting: Always use a dedicated N20 bracket to secure the motor. Avoid applying pressure directly to the gearbox housing to ensure the internal gear alignment is maintained.
• Current Protection: Ensure your motor driver is rated for at least 1A peak to handle the stall current at 12V without overheating the driver chip.
• Soldering: The terminals are delicate. Use flexible 24AWG–28AWG wire and apply heat-shrink tubing to the joints to provide strain relief and protect the tabs from breaking.
• Voltage Management: While it can run at lower voltages (e.g., 6V or 9V), the speed and torque will decrease proportionally. 12V is the recommended "sweet spot" for maximum performance.
