Product Description
The AKH70-48 Hollow Planetary Actuator Module integrates a brushless motor, a proprietary planetary gearbox, encoders, and a drive system into a compact, highly integrated unit. The hollow-shaft design supports internal cable routing, while dual interfaces enable multi-actuator daisy-chain configurations.
The module supports multiple control modes, enabling coordinated control of position, velocity, and acceleration. With adaptive PID control, it reduces tuning complexity while delivering stable output and precise control in a compact form factor, making it well suited for multi-joint robotic systems and automation equipment.

Product Highlights
High Torque Output
Rated torque of 74 Nm with peak torque up to 222 Nm, delivering high joint output in a compact form factor.
Highly Integrated Design
Brushless motor, planetary gearbox, encoders, and drive electronics integrated into a single unit, reducing wiring complexity and simplifying system integration.
Multiple Control Modes
Supports SERVO and MIT control modes, with coordinated position, velocity, and acceleration control. Adaptive PID tuning reduces setup time during commissioning.
Dual Encoder Feedback
Integrated dual 21-bit magnetic encoders (motor-side and output-side) provide reliable closed-loop control. Output position is retained after power loss, ensuring positioning accuracy and system robustness.
Comprehensive Protection Features
Built-in protection against overcurrent, overvoltage/undervoltage, and overtemperature to support stable operation under abnormal conditions.
Flexible Interface Design
XT30PW (2+2) connector integrates power and CAN communication.
UART interface (A1257WR-S-3P) is provided for PC-based configuration and parameter tuning.
Customization Support
CubeMars offers customization options across parameters, interfaces, and functional features to meet specific application requirements.
