Product Views
Highly Integrated Design
KH70-48 integrates a brushless motor, a 48:1 three-stage planetary gearbox, dual encoders, and a driver board into a single unit, delivering improved output performance and control accuracy for high-load joint applications.
7 mm Hollow Design for Simplified Cable Routing
The KH Series adopts a hollow structure that supports routing power and signal cables through the shaft, reducing external wiring while maintaining transmission performance.
Flexible Interface Design
Dual CAN interfaces support multi-module cascading. This design effectively reduces wiring, simplifies the system architecture, and is suitable for robotic platforms requiring coordinated operation of multiple joints.
High Torque Output
With a weight of only 1,396 g, KH70-48 delivers both high output capability and stable continuous operation, meeting the dual requirements of high torque output and lightweight design for joint drives.
Dual Encoder Feedback
A 21-bit inner-loop + outer-loop dual encoder design provides independent position feedback from both the motor side and the output side, effectively reducing the impact of transmission errors on control accuracy while improving system operating consistency and safety.
