N20 Metal Gear Motor 6V 50RPM with Encoder

The N20 Mini Metal Gear Motor with Encoder is a precision DC geared motor featuring an integrated quadrature encoder — purpose-built for closed-loop motor control applications. Operating at 6V with an output speed of 50RPM, this motor enables accurate position tracking, speed feedback, and directional sensing, making it indispensable for advanced robotics and automation systems.

The built-in encoder generates pulse signals as the motor shaft rotates, allowing microcontrollers to measure speed and position in real time. This makes it exceptionally well-suited for applications such as PID-controlled robots, robotic arms, automated guided vehicles, and precision linear actuators where exact motion control is critical.

The all-metal gearbox ensures long-lasting durability and consistent torque delivery under load, while the compact N20 form factor keeps your build lightweight and space-efficient. Compatible with motor drivers such as TB6612FNG and DRV8833, and easily paired with Arduino, STM32, Raspberry Pi, and ESP32 platforms for full closed-loop control implementations.
