Overview

The FEETECH HL-3915 Servo Motor (model HL-3915-C001) is a 12V 14kg double shaft constant force TTL serial bus servo for robotics and automation. It supports absolute position control from 0–360°, multi-loop operation, and half duplex asynchronous serial communication with digital packet control. Coreless motor drive, metal gears, ball bearings, and an aluminium case deliver precise motion with robust mechanical durability. FEETECH HL-3915 provides PID control and comprehensive feedback of load, position, speed, input voltage, current, and temperature.

Key Features

  • TTL serial bus control with digital packet protocol; half duplex asynchronous serial communication.
  • Angle servo mode: absolute position 0–360° with 0.088° resolution (360°/4096), clockwise (0→4095).
  • Multi-loop mode: control of positive and negative 7 turns at highest accuracy (non-saved turns on power loss; resolution can be expanded).
  • Constant force output: set target torque and maintain the commanded torque.
  • Coreless motor, metal gear train, ball bearings, aluminium case; horn gear spline 25T/OD4.95mm.
  • Peak stall torque 14.2kg.cm@12V; no-load speed 0.1sec/60° (100RPM)@12V.
  • Wide rated input voltage: 4V–14V; communication speed 38400bps ~ 1 Mbps; ID range 0–253.
  • Feedback: Load, Position, Speed, Input Voltage, Current, Temperature; PID control algorithm.

Applications

  • Humanoid Robots
  • Robotic Arms
  • Exoskeletons
  • Quadruped Robots
  • AGV Vehicles
  • ARU Robots
