Overview
MyActuator RH-17 Motor is an RH Series harmonic actuator motor designed for robotics joints and automation mechanisms. It supports CAN BUS and EtherCAT communication and uses a dual absolute encoder configuration (ABS-17BIT input and ABS-17BIT output). The RH series is described with features including high precision, low noise, hollow design, high efficiency, and dual encoder feedback.
