Dynamixel XM540-W270-T Servo Motor

Dynamixel XM540-W270-T servo motor: the best results in terms of torque

The XM540-W270-T servo motor stands out from the Dynamixel X-series models for its very powerful stall torque of 10.6 Nm (though it only weighs 165 g). This is particularly interesting for all your robotics projects designed for carrying heavy payloads or exploring difficult terrain.

As compact as the other models in the series (less than 6 cm high and just 3.35 cm wide), it features a TTL connection, is very energy efficient, and includes an improved case offering better heat sink. Benefiting from a high-quality motor and the right choice of materials, this servo is as reliable as it is durable.

A Robotis servo you can control from A to Z

Robotis has developed a whole range of fully programmable servos that you can control in every aspect. PWM, position, consumption, temperature, speed... This servo provides extensive feedback, as always. Six control modes are available: torque, position, velocity, extended position, current-based position and PWM. It also includes a PID controller, a popular regulator used in industrial applications.

In short, you’ll have a servo ready in all circumstances, from prototyping to competition robots to autonomous navigation or robotised arms. The Dynamixel XM540-W270-T servo motor adapts just as well to use in a classroom environment as in a research lab, or for developing automated process solutions.
