AEROFOX-DAMIAO-J4310-2EC
The DM-J4310-2EC V1.1 is a compact integrated joint motor designed for lightweight robotic arms and precision motion control applications. With high torque density and an integrated magnetic encoder, it provides stable and accurate joint control through CAN / CAN-FD communication.
In the OpenArm open-source robotic arm, the DM-J4310-2EC is typically used in the wrist joints (J5–J6) where compact size, fast response, and smooth motion are essential. It enables precise end-effector positioning for tasks such as gripping, tool manipulation, and fine robotic operations.
