Dynamixel XH540-W150-R Servo Motor

Dynamixel XH540-W150-R Servo Motor: a high-quality 12V motor

Like all the Robotis XH series servos, the XH540-W150-R model includes a high-quality Maxon motor, which is more hard-wearing and reliable than the equipment installed on the XM series. The Dynamixel XH540-W150-R Servo Motor offers not only an RS-485 connection but also speed, position and PWM control, with a gear ratio of approximately 150:1.

It has a gold-plated JST connector, which is of a higher quality than the Molex connectors used in the previous series. And its precious metal and engineering plastic casing delivers effective protection and satisfactory heat dissipation.

Dynamixel XH servos: an all-in-one Dynamixel

These Robotis Dynamixel servos combine a controller, motor, reduction gearbox, incremental encoder and magnetic encoder in a single component. Its all-in-one system allows you to assemble the servo on your robot without adding other modules. All you’ll need is a power supply and a communication module. It comes with its own JST-Molex cable allowing you to connect your servo to a compatible controller or U2D2 Dynamixel module.

With the Dynamixel XH series, you can connect multiple servos in a chain for a much cleaner assembly. The 6-port RX/EX Power Hub allows you to power up to 6 servo chains in parallel. Plus, it is a servo that offers numerous assembly configurations, including 3 different wiring arrangements.
