CubeMars AK70-9 KV60 Motor
CubeMars AK70-9 KV60 Motor
Product Description
The CubeMars AK70-9 KV60 robotic actuator integrates a brushless DC motor, 9:1 planetary gearbox, and driver into a compact, easy-to-install unit. It delivers high torque output while maintaining responsive dynamics. The module supports multi-loop control (position, speed, torque, and MIT hybrid mode) with dual encoder feedback, and includes built-in protection against overcurrent, overvoltage/undervoltage, and overheating for stable operation in demanding applications.
Upper computer enables one-click parameter identification and seamless switching between servo and MIT modes, significantly simplifying commissioning. Real-time status monitoring ensures precise control and reliable communication in complex scenarios. Ideal for robotic joints and precision medical devices, this actuator also supports customization, providing a high-performance, dependable power solution for industrial automation and research applications.
