Dynamixel XH540-W270-R servo motor: all-in-one and all-terrain

This Dynamixel servo offers a reduction ratio of 275:1 which makes it a great fit for robotic devices exploring difficult terrain. It is slower than the XH540-W150-R model, but it generates a more powerful torque.

Performance of Dynamixel X-series servomotors

As with all the XH series servos, you’ll benefit from an all-in-one device: you’ll only need to connect it to your controller or a USB2Dynamixel module and a power supply to get immediately started. Fully programmable, it offers extended torque, position, velocity or PWM control with a total of 6 operating modes. You can use the provided JST-Molex cable to connect it to its controller, as the Dynamixel XH540-W270-R servo motor has a gold-plated JST-compatible connector, which is much more reliable than the Molex connector used in the previous series.

A high-quality Dynamixel servo with numerous mounting options

The Dynamixel XH540-W270-R servo motor benefits from a high-quality design: its precious metal and engineering plastic casing delivers satisfactory heat dissipation.

At the back of the case, you can position the connection cable in 3 different arrangements. And with the suitable frames, you can mount your Dynamixel servo in many configurations, which is particularly useful if you’re planning to build a complex robot.

Finally, the Dynamixel XH540-W270-R servos can be linked together in a daisy chain.
