Overview

The FEETECH HL-3930 Servo Motor is a 12V, 35kg double shaft constant force serial bus servo designed for precise motion control in robotics and automation. This servo motor combines a steel geartrain, aluminium case, ball bearings, and 25T/OD5.9mm horn spline with a half duplex asynchronous serial communication interface. It supports PID control, absolute 0–360° positioning, multi-loop operation, and real-time feedback of load, position, speed, input voltage, current, and temperature.

Key Features

  • 12V 35kg double shaft constant force serial bus servo
  • Absolute 0–360° position control, 0.088° resolution (360°/4096)
  • Operating modes: Angle servo (Mode 0), motor constant speed (Mode 1), motor constant current (Mode 2)
  • Multi-loop control: ±7 turns at highest accuracy (turns not saved after power-off; resolution expandable)
  • Constant force output: set target torque (address 44) to maintain torque
  • Digital Packet command signal; Half Duplex Asynchronous Serial Communication
  • Communication speed: 38400bps ~ 1 Mbps; ID range 0–253
  • Feedback: Load, Position, Speed, Input Voltage, Current, Temperature
  • Steel Gear, ball bearings, aluminium case; 25T/OD5.9mm horn gear spline
  • Gear Ratio 1/345; connector wire 15CM
  • Compact size (A：45.22mm B：24.72mm C：35mm); weight 70.5± 1g
  • No load speed 0.222sec/60°(45RPM)@12V; peak stall torque 35kg.cm@12V
