Technical Drawing
The CubeMars AK80-64 KV80 robotic actuator integrates a brushless DC motor, proprietary planetary gearbox, encoder, and driver into a compact, easy-to-install unit. Featuring a 64:1 gear reduction, it excels in low-speed, high-torque applications while maintaining control precision and responsive performance. The module supports both servo and MIT hybrid control modes, includes adaptive PID parameter identification, and integrates protection against overcurrent, overvoltage/undervoltage, and overheating for reliable operation in challenging environments.
Motor Dimensions: Ф98*61.9mm
Motor Weight: 850g
Peak Torque: 120Nm
No-load Speed: 75rpm
High Torque Density: Delivers up to 120 Nm peak torque in a compact package, ideal for high-load applications
Fully Integrated Design: Combines BLDC motor, gearbox, driver, and encoder to minimize wiring and mechanical complexity
Flexible Control: Supports servo and MIT hybrid control modes with auto-tuning PID for fast deployment
Comprehensive Protection: Built-in overcurrent, overvoltage/undervoltage, and overtemperature protection enhances system reliability
Optimized Connector: Plug-in interface replaces traditional wire harnesses, simplifying installation and maintenance
Wide Application Range: Suitable for robot hip joints, exoskeletons, collaborative arms, and high-load limb appliacations
