Mini Micro N20 Gear Motor DC 3V-6V Slow Speed
Compact All-Metal Gear Motor for DIY Robotics and RC Projects
The N20 is a miniature DC motor featuring a lowspeed, hightorque gearbox, ideal for projects requiring precise, controlled movement. Its compact size makes it a favorite for DIY robot cars and small mechanisms [citation:1][citation:2].
Durable AllMetal Gearbox Provides reliable torque and long service life for demanding applications [citation:1][citation:2].
Broad Speed Selection - Choose from various RPM options to match the speed and torque requirements of your project [citation:5][citation:10].
Operating voltage range is typically 3V to 6V DC with 3mm D-shaped output shaft for secure wheel mounting [citation:1][citation:2].
For easy control, consider a version with an integrated motor driver that uses a single PWM signal [citation:9].
The motor's speed varies with voltage (e.g., 55 RPM at 5V vs 65 RPM at 6V). Always confirm the specific speed rating of your chosen model [citation:1].
