  1. Precisely designed and specially processed Aluminum front case
  2. Decreased noise and improved protection against heat
  3. Front screw threads are already threaded for easy bolt assembly
  4. Maintains same dimensions as the existing DYNAMIXEL M-series (option frames are compatible)


DYNAMIXEL is a robot exclusive smart actuator with fully integrated DC Motor + Reduction Gearhead + Controller + Driver + Network in one DC servo module.
MX-series is a new concept of DYNAMIXEL with advanced functions, such as precise control, PID control, 360 degree of position control, and high speed communication.
    Advanced durability, degree of precision, and wider control zone were achieved thanks to the newly applied
    360 degrees POSITION CONTROL without dead zone
    4,096 PRECISE RESOLUTION by 0.088 degrees
    Reliability and accuracy were advanced in the position control through PID CONTROL
    High baud rate up to 4.5Mbps
