The N20 12V 300 RPM Micro Metal DC Gear Motor is the industry standard for high-torque, miniature motion control. At Electrapac, we recommend this motor for robotics enthusiasts and engineers in Bangladesh who are building palm-sized robots, electronic locks, or precision medical prototypes where space is limited but power is essential.

Product Overview

The N20 is a tiny but mighty motor that combines a coreless DC motor with an all-metal gearbox. Unlike plastic-geared motors, the all-metal construction of this module ensures it can handle high stalls and heavy loads without stripping the teeth. Its rectangular shape and cross-shaped output shaft make it incredibly easy to mount and compatible with a wide variety of wheels and couplers. 

Key Features for Electrapac Customers

• Precision All-Metal Gears: Built for durability and long life, these gears provide a significant torque boost, allowing this tiny motor to push objects many times its own weight.

• Ultra-Compact Size: Small enough to fit inside a matchbox, making it ideal for micro-sumo robots, smart home gadgets, and DIY camera gimbals.

• D-Shaped Output Shaft: The flat side on the 3mm shaft ensures that wheels and gears stay locked in place and do not slip, even under high vibration.

• Low Noise & High Efficiency: Optimized for smooth rotation with minimal friction, preserving battery life in portable IoT devices.

• Easy Mounting: Features two M1.6 threaded holes on the front of the gearbox for secure attachment to any chassis or bracket.

Installation & Usage Tips

To get the best performance from your Electrapac N20 motor, consider the following:

1. Driver Compatibility: This motor can be easily driven using an L298N, L293D, or the tiny DRV8833 motor driver.

2. Direction Control: Simply reverse the polarity of the two wires on the back of the motor to change the direction of rotation.

3. Shaft Care: While the gears are metal, avoid applying extreme side-loads (perpendicular to the shaft) to prevent bending the internal motor housing.

Pro-Tip: If you need to monitor the exact speed or position of your motor, look for the N20 Encoder Version (also available at Electrapac), which includes a magnetic disk and Hall-effect sensors on the rear.

Primary Applications

• Micro Robotics: Perfect for 2WD and 4WD mini robots that require precise turning and speed.

• Electronic Smart Locks: Driving the locking mechanism in fingerprint or RFID-based security systems.

• Precision Medical Devices: Used in miniature pumps and rotating dispensers.

• Automated Blinds: Small enough to be hidden inside a window blind rail for smart home automation.

• DIY Camera Sliders: Providing smooth, slow motion for professional-looking video shots.
