A compact, lightweight actuator integrating a BLDC motor, 9:1 planetary gearbox and driver, tuned for smooth, quiet operation in exoskeletons and robot limb joints.
The CubeMars AK80-9 V3.0 KV100 integrates a brushless DC motor, 9:1 planetary gearbox and driver board into a compact, easy-to-install unit. It delivers enhanced torque output and control stability while staying highly responsive, supporting multi-loop position, speed, torque and MIT hybrid control.
A new upper computer adds one-click intelligent parameter identification and seamless switching between servo and MIT modes, with plug-in connectors and built-in overcurrent, overvoltage/undervoltage and overheating protection – ideal for collaborative arms and robot limb joints.
