The 6V 210:1 75RPM Micro Metal Gearmotor with Encoder is a compact, high-precision DC gearmotor designed for robotics, automation, and DIY electronic projects that require accurate motion control and feedback. Featuring a durable metal gearbox and a built-in Hall-effect encoder, this motor delivers excellent torque output with precise speed measurement.
This gearmotor operates at a rated voltage of 6V, with a no-load speed of 75 RPM and a gear reduction ratio of 210:1, making it an ideal choice for applications demanding high torque and controlled movement. The integrated encoder provides 420 pulses per revolution, enabling real-time monitoring of motor speed and position for closed-loop control systems.
Equipped with a 9.0 mm D-profile metal output shaft, the motor is fully compatible with Pololu wheels (42x19mm and 32x7mm), ensuring easy integration into a wide range of mechanical assemblies. Its lightweight yet robust construction (only 18 g) makes it suitable for compact robots and precision devices.
