Solution

The core challenges and requirements for driving technology of AGV composite robots

Energy limitation: AGV is powered by onboard batteries (usually 24V, 48V, etc.) with limited power. All systems must be efficient and energy-saving to
extend the running time of a single charge.


Space and weight limitations: The AGV body has a compact space, and lightweight design is crucial. Drive components need to be miniaturized and
lightweight


Precise handling during movement: AGV may experience slight shaking or start stop impact while in motion. The robotic arm must be able to resist
this fundamental disturbance and maintain a stable and precise trajectory.


High safety requirements: When working in a dynamic environment where human colleagues may coexist, the system must have high safety standards,
including collision detection, torque limitation, and rapid response.   


  


The low-voltage servo drive directly uses the AGV's DC bus voltage (such as 24V, 48V), without the need for additional boosting or complex power
conversion modules. This reduces energy conversion losses and improves overall energy efficiency.

Low voltage servo motors use high-performance permanent magnet materials and high slot full rate winding technology to output greater torque in
a smaller volume. The driver also adopts a compact design and can even be integrated into the interior of the motor (modular or integrated design)

High responsiveness: Low voltage servo has extremely high bandwidth and response frequency, which can quickly respond to position, speed, and
torque commands

Advanced control algorithm: Built in advanced filters and vibration suppression functions can effectively counteract low-frequency vibrations caused
by AGV mobile platforms, ensuring smooth movement of the robotic arm end

High resolution encoder: using a multi turn absolute value encoder, no need to reset to zero when turned on, and can maintain accurate positioning
memory even when moving


STO function: Integrated safety torque cutoff function, meeting functional safety standards
