The biggest advantage of high-voltage servos is not “more energy-efficient,” but rather achieving higher transmission efficiency with lower operating current at the same torque and power output. This not only reduces voltage drops and line heating but also improves power supply stability, making the servos more stable and reliable in high-load, long-term operation, and multi-servo synchronous operation scenarios. The “energy-saving” advantage of high-voltage servos is relative: under normal operating conditions, it is indeed more efficient and energy-saving with lower heat generation; however, under violent and extreme operation, it is a double-edged sword, with a surge in performance but also severely testing the power supply margin of the entire power system. Proper use of high-voltage platforms requires reserving sufficient current redundancy for extreme scenarios.
