The CubeMars AK80-9 KV100 robotic actuator integrates a high-performance brushless DC motor, planetary gearbox, driver board, and encoder into a compact, easy-to-install unit. As a key model in the CubeMars AK series, it delivers balanced performance in torque and speed. It supports servo and MIT hybrid control modes (position, speed, torque), features auto PID parameter identification, and includes integrated protection against overcurrent, overvoltage/undervoltage, and overheating for stable and reliable operation in complex environments. With strong torque output, it is an ideal choice for quadruped robots, exoskeletons, joint drives, and similar applications.
Motor Dimensions: Ф98*38.5mm
Motor Weight: 485g
Peak Torque: 18Nm
No-load Speed: 533rpm
Fully Integrated Design: Combines motor, gearbox, driver, and encoder into one unit, minimizing external wiring and component complexity
Balanced Performance: 9:1 gear reduction provides an optimal balance between speed and torque for medium-load applications
High Peak Torque: Delivers up to 18 Nm peak torque output
Dual Control Mode Support: Switchable between servo and MIT hybrid control modes for flexible adaptation to various control requirements
Auto PID / Parameter Adaptation: Simplifies tuning process and improves development efficiency
Comprehensive Protection: Built-in overcurrent, overvoltage/undervoltage, and overtemperature protection enhances system safety
Plug-in Interface: Reduces cable clutter, improves module interchangeability and connection reliability
Wide Application Range: Suitable for exoskeletons, quadruped robots, robotic arm joints, and other applications
