The Dynamixel XH540-W270-T servo motor generates one of the most powerful torque in the Dynamixel X series. It offers all the advantages of Robotis XH servos in terms of high-quality design and control modes–plus a TTL interface.
Dynamixel XH540-W270-T servo motor: a powerful TTL version
With a 9.9 Nm starting torque and a 272.5:1 reduction ratio, the Dynamixel XH540-W270-T servo motor is making a name for itself as one of the most powerful actuators in its class. Similar to the XH540-W270-R model in terms of performance, this servo offers for its part a multidrop bus TTL interface.
Particularly well suited for building mobile robots meant to explore rough terrain, this Dynamixel servo also stands out for its numerous programming possibilities. You’ll benefit from 6 control modes, including in PWM mode, which will delight fans of radio-controlled vehicles. You can connect it directly to a PC using a U2D2 Dynamixel module or an Arduino microcontroller (or any compatible controller) thanks to the provided JST-Molex cable.
Dynamixel XH series servo motors: extreme manufacturing quality
The programmable servos in the Dynamixel XH range benefit from a high-quality design in many ways:
The gold-plated JST connector ensures more reliable and stable communications than a Molex connector;
The precious metal and engineering plastic casing delivers very satisfactory heat dissipation;
3 different arrangements are possible for the cable at the back of the case, and numerous assembly configurations are possible thanks to a wide range of compatible frames.
