Dynamixel XD540-T270-R servo motor

New XD series: the Dynamixel servo motors are constantly evolving

The Dynamixel XD540-T270-R servo motor has an integrated gearhead, controller, network and driver. Like the Robotis XH range, it includes features attractive to amateur roboticists. You can use this smart servo motor, with its reliable torque, to control velocity, position, current, torque and PWM.

Just as compact and powerful as the other Dynamixel 100% programmable servo motors, this servo offers a new advantage: it lasts significantly longer that the XH, because the Dynamixel XD540-T270-R servo motor benefits from a 230% increase in service life!

6 operating modes in a compact and robust case

The Dynamixel XD540-T270-R servo motor has the same form factor as the servos in the XH and XM series – and you can combine these different series in the same assembly.

Dynamixel has made no compromises in terms of performance: a robust torque, low current consumption and, most importantly, six operating modes and a wider range of feedback. And the Dynamixel XD540-T270-R still offers all the benefits of an industrial grade component.
