Overview
The CubeMars AK80-9 KV100 Robotic Actuator is a high-integration, lightweight drive module designed for legged robots, exoskeletons, and AGVs. It combines a brushless DC motor, 9:1 planetary reducer, magnetic encoder, and FOC drive into a compact 485g package. With 9Nm rated torque, 390rpm speed, and KV100 performance, this actuator offers precise, smooth, and powerful motion control. Supporting both servo and MIT modes, the AK80-9 ensures real-time synchronization of position, velocity, and acceleration while simplifying control through automatic PID adaptation.
