Servomotor Dynamixel MX-12W

Dynamixel Servo Robotis : MX-12W

The Servo Dynamixel MX-12W by Robotis 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 CONTACTLESS ABSOLUTE ENCODER
• 360 degrees POSITION CONTROL without dead zone
• 4,096 PRECISE RESOLUTION by 0.088 degrees
• SPEED CONTROL at ENDLESS TURN MODE
• Reliability and accuracy were advanced in the position control through PID CONTROL
• High baud rate up to 4.5Mbps
• Shape of the AX-series + durability of the MX-series
