Details

Compact planetary gearmotor body integrates the brake and onboard interface in a single actuator package.

A clearly defined output end and fixed end helps simplify mechanical integration and alignment in assemblies.

Encoder feedback and bus communication support stable torque, speed, and position control for robotics joints.

Designed for robot actuation tasks from AGVs and robotic arms to legged robots and exoskeleton systems.

Port definitions cover power, RS485/CAN wiring, and UART pins, with an onboard ID switch for addressing.
