Product structure

Product Features
This serie robot joint modules are highly integrated high density torque motor, full hardware FOC drive, high precision encoder and harmonic reducer.

Ultra-Thin Drop Lock
The ultra-thin locking mechanism of the harmonic joint module not only achieves the ultimate compression of physical space, but also redefines the safety boundary. It enables robots to have a more slender arm span, a more flexible posture, and the reliability of remaining on duty even in the event of power failure.
Full hardware FOC drive design
Hardware-level current loop control improves dynamic response speed to microsecond level. Under working conditions such as high-speed start and stop, sudden load changes, and external disturbances, torque compensation can be completed instantly to ensure the flexibility and impact resistance of joint motions, far exceeding traditional software FOC solutions.


No gap No backlash
It adopts zero-backlash harmonic transmission design to ensure two-way motion engagement without backlash. Transmission error of ≤20 arc seconds provides a nanoscale response basis for trajectory repeatability and cutting roundness.
Full closed-loop rigid transmission from the input end to the output end. The minimally backlash design effectively suppresses system resonance, enhances servo gain, and thereby achieves faster response speed and lower tracking error.
No wear and tear
Extend the replacement cycle of core components with wear control technology. Reduce equipment life cycle maintenance costs, reduce downtime losses due to gear wear, and achieve longer maintenance-free operation time.
It has been verified through cumulative thousands of hours of full-load life tests. Under the rated load, the transmission efficiency and accuracy retention capabilities exceed industry standards, ensuring the reliability of long-term continuous operation.


Brake smooth and stable
The non-inductive transition from dynamic motion to static locking uses a servo-level braking control algorithm to effectively suppress position overshoot and mechanical resonance at the moment of stopping, ensuring the perfect finish of high-precision processes.
Smooth braking ensures the utmost precision in maintaining the position at the moment of stop, making each sudden stop feel like pressing the pause button rather than the fast-forward button.
Support CANopen and Ethercat
Standard CANopen and EtherCAT communication interfaces, compatible with various mainstream controllers. Make system integration more flexible and efficient.
Flexible and adaptable to different-sized robot systems. Supports bus cascading and distributed clocks, from single-axis control to synchronous networks with dozens of axes, all maintaining real-time communication and data consistency.
