SPIDER Automation N20 Micro Metal Gear Motor with Encoder | 6V 30 RPM | High-Torque Precision Robotic Actuator
Description
Engineered for miniature robotics, automated smart vehicles, and precise motion control setups, the SPIDER Automation N20 Micro Metal Gear Motor with Encoder combines a tiny physical footprint with immense mechanical torque. Operating natively at 6V DC across a comfortable 3V to 6V operational range—with rotation starting as low as 0.5V—this GA12-N20 model features a robust 298:1 gear ratio delivering a controlled 30 RPM output speed. It comes equipped with an integrated encoder system that outputs real-time rotational feedback pulses, making it perfect for tracking movement and odometry. Supplied with a 14cm connector cable and standard D-type output shaft, it connects effortlessly to microcontrollers like Arduino for advanced closed-loop projects.
