Preload optimization method for traveling-wave rotary ultrasonic motor

HIGHLIGHTS

  • who: Haoyu Sun and colleagues from the School of Mechanical and Automotive Engineering, Qingdao University of Technology, Qingdao, China have published the Article: Preload Optimization Method for Traveling-Wave Rotary Ultrasonic Motor, in the : Processes 2021, 1164 of /2021/
  • what: In this paper a novel method for a traveling-wave rotary is proposed.
  • how: The experimental results showed that when the preload was optimized from 200 N to 310 N the stalling torque of the increased by 20.7% the maximum efficiency increased by 15.3% the standard deviation of the speed decreased . . .
