The CubeMars AK70-10 KV100 robotic actuator integrates a high-performance brushless DC motor, 10:1 planetary gearbox, driver board, and encoder into a compact, easy-to-install unit. Featuring a 10:1 gear reduction, it delivers increased torque output while maintaining fast response times. The module supports multi-loop control (position, speed, torque, and MIT hybrid mode), includes plug-and-play connectors and auto PID parameter identification, and features built-in protection against overcurrent, overvoltage/undervoltage, and overheating for stable operation in demanding environments.

Motor Weight: 521g
Peak Torque: 24.8Nm
No-load Speed: 480rpm
Integrated Design: All-in-one integration of motor, planetary gearbox, driver, and encoder significantly reduces system complexity
High Torque Density: Rated output up to 8.3 Nm, peak up to 24.8 Nm, suitable for medium to high-load applications
High-Precision Feedback: 14-bit magnetic encoder enables accurate position and speed control
Flexible Control Modes: Supports position, speed, torque, and MIT hybrid control modes
Comprehensive Protection: Built-in overcurrent, overvoltage/undervoltage, and overtemperature protection ensures long-term reliability
Broad Application Range: Designed for exoskeletons, quadruped robots, collaborative arms, and other dynamic robotic systems
