MX-28AT

12.0V / 2.50Nm / 55.00rpm / Coreless(Maxon) / TTL

Features

DYNAMIXEL is a robot exclusive smart actuator with fully integrated DC Motor + Controller + Driver + Sensor + Reduction Gear + 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
