## Description

The DFRobot 12V Low Noise DC Motor (Model 28PA51G) is a quiet, high-torque geared motor with a built-in two-phase hall encoder. Designed for applications where noise is a concern, it produces approximately 57–68 dBA under no-load conditions — making it well suited for indoor robotics and equipment. The integrated encoder delivers 13 pulses per revolution at the motor shaft, which translates to 663 PPR at the gearbox output (51:1 ratio). This enables precise speed measurement and closed-loop position control using standard interrupt-based code on Arduino or similar microcontrollers. Key Features Low Noise Operation – Approximately 57–68 dBA at 10 cm under no-load conditions High Torque Output – 10 kg·cm rated torque at 12V Two-Phase Hall Encoder – 13 PPR motor shaft / 663 PPR gearbox shaft for direction and position sensing 51:1 Planetary Gearbox – 146 RPM no-load output speed at 12V 6-Pin Connector – Motor power and encoder signals on a single cable Specifications Model – 28PA51G Working Voltage – 12V DC No-Load Speed (motor) – 8000 RPM No-Load Speed (gearbox) – 146 RPM @ 12V No-Load Current – 0.23A @ 12V Stall Current – 3.6A Rated Torque – 10 kg·cm @ 12V Gear Ratio – 51:1 Encoder Resolution – 13 PPR (663 PPR at gearbox shaft) Noise – ~57–68 dBA @ 10 cm (no load) Dimensions – 123 × 36 × 36 mm Weight – 270 g Ideal For Indoor mobile robots and service robots Noise-sensitive motorised equipment Closed-loop speed and position control projects Robotics platforms requiring precise encoder feedback Package Contents 1× 12V DC Motor with Encoder (28PA51G) 1× Encoder Cable 1× Encoder Board (FIT0324) Resources Wiki Documentation – Wiring diagrams, encoder connection details, and sample Arduino code Mechanical Drawing
