• The N20 Gear Motor with 3x7mm D-Shaft and 20mm motor body is a premium micro DC geared motor designed for precision applications requiring high torque in a tiny package. Featuring a robust metal gearbox and a D-cut shaft (3mm round diameter with 7mm flat measurement for anti-slip fitting), this motor ensures secure attachment of gears, wheels, or couplings without slipping.  
• The compact 20mm motor length (body excluding extended gearbox) makes it ideal for tight spaces in robotics projects, RC models, smart door locks, automated toys, camera gimbals, and small mechanisms. The metal construction provides excellent durability, low noise, and resistance to wear compared to plastic gearbox variants.  
• Operating on 3V to 12V DC, it offers a wide range of speed and torque options depending on the gear ratio – from slow high-torque for precise movements to faster speeds for quick actions. With reversible polarity for bidirectional rotation, it’s perfect for Arduino, Raspberry Pi, or any microcontroller-based DIY electronics. Reliable performance, easy integration, and availability in Bangladesh make this N20 variant a top choice for hobbyists and engineers.
