问题二：如何降低系统能耗？

Question 2: How to reduce system energy consumption?

争议点：传统丝杠传动效率低下（＜50%）

Controversy point: Traditional screw drive has low efficiency (<50%)

解决方案：

Solution:

滚动摩擦技术：

Rolling friction technology:

精密钢球（G10级）循环系统

Precision steel ball (G10 grade) circulation system

摩擦系数降0.003-0.005

The friction coefficient drops to 0.003-0.005

能效数据：

Energy efficiency data:

驱动扭矩仅为滑动丝杠1/3

The driving torque is only one-third of that of the sliding screw

实测功率损耗降低67%

Tested power loss reduced by 67%
