CubeMars AK80-64 KV80 Motor
CubeMars AK80-64 KV80 Motor
Product Description
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.
