DDSM350-CT
This product is an integrated servo hub motor with a compact 4.5inch outer‑diameter design. It highly integrates an outer‑rotor brushless motor, high‑precision encoder and servo drive, featuring simple installation. It is suitable for direct‑drive applications such as robot joints, compact AGVs and service robots. The motor delivers a rated torque of 1.1 N·m, peak torque of 3 N·m and a maximum speed of 350 rpm. It provides precise, low‑noise motion control, supports dual‑communication via UART and CAN, and incorporates multiple protections including over‑voltage and over‑temperature and short‑circuit protection. It reaches an IP67 ingress‑protection rating (excluding the shaft end), delivering a reliable and efficient direct‑drive solution for mobile robots.
