Metal DC Geared Motor w/Encoder - 12V 83RPM 45Kg.cm

This 12 V DC geared motor (model GB37Y3530-12V-83R) pairs a powerful brushed motor with a 131:1 metal gearbox and an integrated Hall-effect quadrature encoder. The encoder provides 16 counts per revolution on the motor shaft — equivalent to 2096 counts per revolution on the gearbox output — giving precise speed and position feedback for robotics and automation projects.

The 6 mm D-shaped output shaft extends 15.5 mm from the faceplate, which features six evenly spaced M3-threaded mounting holes arranged in a regular hexagon with 15.5 mm centre-to-centre spacing. The motor can begin rotating from as low as 1 V, making it suitable for variable-speed applications.
