The N20 Gear Motor is a miniature, ultra-high-speed DC motor equipped with a precision metal reduction gearbox. The 12V 1000RPM variant is engineered for maximum speed and rapid response, making it the most aggressive performer in the N20 series. It is primarily used in competitive micro-robotics and high-frequency automated systems where velocity is the primary requirement.

Specifications

• Rated Voltage: 12V DC (Effective range: 6V – 14V).
• No-Load Speed: 1000 RPM (at 12V).
• Shaft Type: D-shape (flat side for non-slip mounting).
• Shaft Diameter: 3mm.
• Shaft Length: 10mm.
• Gearbox: Full Metal (Brass and steel alloy).
• No-Load Current: ~ 60mA.
• Stall Current: ~ 1.2A (at 12V).
• Stall Torque: ~ 0.2 kgcm to 0.4 kgcm.

Features

• Ultra-High Speed: At 1000 RPM, this motor provides exceptionally fast rotation, allowing micro-vehicles to achieve high top speeds on flat surfaces.
• All-Metal Gear Train: The precision-cut metal gears provide significantly higher durability and heat resistance than plastic gears, which is critical for the high friction generated at 1000 RPM.
• Miniature Footprint: The compact rectangular design allows for high-density integration in small drones, specialized tools, and compact consumer electronics.
• Standardized D-Shaft: The 10mm length ensures compatibility with a wide variety of wheels, brass couplers, and plastic pulleys without the risk of the attachment spinning freely.

Pin and Connection Guide

• Terminals: Two solder tabs at the rear of the motor housing.
• Directionality: Swapping the positive and negative power leads will instantly reverse the motor's rotation direction.
• Speed Control: Highly responsive to Pulse Width Modulation (PWM), allowing for smooth speed ramping from low to high RPM.

Common Applications

• Competitive Micro-Robots: High-speed line followers and "Ant-weight" or "Fairy-weight" combat robots where speed is used for impact.
• High-Frequency Actuators: Rapid-fire mechanisms in toy launchers or automated sorting machines.
• Medical Equipment: Driving miniature high-speed centrifuges or rapid fluid mixers.
• Optical Systems: Fast-acting shutters or high-speed mirror positioning in scanning devices.

Usage Tips

• High Current Protection: Due to the 1.2A stall current, ensure your motor driver (like the TB6612FNG) is rated for high peaks to prevent thermal shutdown.
• Gear Maintenance: At 1000 RPM, friction is high. A small amount of molybdenum-based grease can help reduce noise and extend the life of the gears.
• Vibration Management: High-speed motors can create significant vibration. Ensure the motor is securely mounted using a dedicated metal N20 bracket to maintain alignment.
• Inertia Warning: Because this motor spins very fast, it has significant rotational inertia. Sudden stops can put immense stress on the tiny metal teeth; if possible, use "coast to stop" or soft-braking in your code.
