AI Technical Summary

Technical Problem

Existing motor drivers have problems with low efficiency and large size of power devices. In particular, they generate large switching losses during high-frequency switching, which leads to severe overheating of the servo motor driver and affects the endurance of humanoid robots.

Method used

Gallium nitride power devices are used as the power module of the motor drive device. Combined with communication and processing modules, high-efficiency and high-frequency switching is achieved. The communication module communicates with the internal motor drive device of the robot to achieve collaborative work.

Benefits of technology

This reduces heat generation in the motor drive unit, achieving high efficiency and miniaturization, and improves the endurance and collaborative working capabilities of the motor drive unit.
