Abstract

This article introduces a method of enhancing the energy conversion efficiency of a traveling wave rotary ultrasonic motor with a flexible rotor by increasing the friction coefficient at the stator–rotor interface. The increased friction coefficient leads to improvements in energy conversion efficiency by increasing the output power and reducing friction loss power. Experimental verification showed that the friction coefficient in the interface increased from 0.21 to 0.32, the maximum energy conversion efficiency increased from 36.8% to 46.3%, and the interface friction loss was reduced.

通过增加摩擦系数提高行波旋转超声波电机的能量转换效率

本文介绍了一种通过增加定转子界面摩擦系数来提高带柔性转子的行波旋转超声波电机能量转换效率的方法。摩擦系数增大后，输出功率增大，摩擦损耗功率减小，从而提高了能量转换效率。实验验证表明，界面摩擦系数从 0.21 增加到 0.32，最大能量转换效率从 36.8% 提高到 46.3%，界面摩擦损耗降低。
