Description:
The Waveshare 20 kg.cm High Torque Bus Servo Motor is a high-performance programmable smart servo designed for advanced robotics and automation projects. Equipped with a 360° high-precision magnetic encoder, it delivers accurate position feedback, smooth motion control, and reliable closed-loop operation. With a maximum speed of up to 106RPM and 20 kg.cm torque output, this servo is ideal for applications requiring both power and precision.
The servo supports multiple operating modes, including angle control mode, continuous rotation mode, and stepper motor mode, providing exceptional flexibility for robotics developers. Built-in acceleration and deceleration algorithms ensure smooth starts, stops, and precise movements while reducing mechanical stress.
Featuring a UART serial bus interface, multiple servos can be daisy-chained together, allowing control of up to 253 servo motors on a single communication bus. Real-time feedback data such as position, load, voltage, temperature, and operating mode enables advanced monitoring and intelligent control.
