SPIDER Automation N20 Micro Metal Gear Motor with Encoder | 3V 35 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 3V DC—with rotation starting as low as 0.5V—this GA12-N20 model features a heavy 298:1 gear ratio delivering a controlled 35 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.
Key Features
- Built-In Quadrature Encoder: Real-time signal feedback pulses (3 PPR) for accurate speed regulation and position tracking.
- GA12-N20 Micro Build: Ultra-compact dimensions (15 x 12 x 10 mm) allowing seamless integration into restricted spaces.
- Robust Metal Gearing: Fine craftsmanship and durable metallic gear reduction designed for high wear resistance.
- Superior Stall Characteristics: High stall torque (2 kg-cm) providing excellent hill-climbing and load-bearing capability.
- Ready-to-Use Harness: Includes a 14cm connector cable mapped cleanly for immediate hookup.
