    DYNAMIXEL is a robot exclusive smart actuator with fully integrated DC Motor + Reduction Gearhead + Controller + Driver + Network in one DC servo module.

    The DYNAMIXEL XH / XM-Series offers a variety of control techniques based on high-performance current sensing algorithms.

    It adopts the aluminum case and adopts the new technology such as the hollow cable fastening structure for users’ convenience.

    1. 6 Operating Modes

    Torque Control, Velocity Control, Position Control, Extended Position Control, Current based Position Control, PWM Control

    2. Profile Control for Smooth Motion Planning

    3. Improved Heat Sink Featuring an Aluminum Case

    4. Hollow Back Case Minimizes Cable Stress (3-way-routing)

    5. Direct Screw Assembly to the Case (without Nut Insert)

    6. Energy Saving (Reduced Current from 100mA to 40mA)

    7. 28.4% reduced volume compared to the MX-106

    8. Support synchronous control mode

    9. Support external I / O port support
