Overview

FEETECH HL3640M Servo Motor (servo model: HL-3640-C001) is a 7.4V 40kg.cm single shaft constant force serial bus servo with digital packet control and half-duplex asynchronous serial communication.

Key Features

Constant force output: set a target torque value; the servo maintains the specified torque (target torque value corresponding to address 44).
Operating modes: Mode 0 angle servo mode (default, absolute position controllable from 0–360 degrees); Mode 1 motor constant speed mode; Mode 2 motor constant current mode (can achieve absolute position).
Multi-loop mode: control of positive and negative 7 turns at the highest accuracy; number of turns after power failure is not saved (resolution can be expanded and the number of turns can be doubled).
Feedback: Load, Position, Speed, Input Voltage, Current, Temperature.
Steel gears, aluminium case, ball bearings.
